I have written a PropertySource that enables classpath: prefix for spring.kafka.properties.ssl.truststore.location (which out-of-the-box is not supported).
Essentially, this lets me place a truststore.jks inside my Spring Boot application's src/main/resources folder and reference it from inside the .jar file.
This works nicely for plain Spring Kafka configurations, like these:
spring:
kafka:
properties:
ssl.truststore.location: classpath:myTruststore.jks
It currently fails when the same configurations are given in the context of a Spring Cloud Stream Binder:
spring:
cloud:
stream:
binders:
my-binder:
type: kafka
environment:
spring:
kafka:
properties:
ssl.truststore.location: classpath:myTruststore.jks
My PropertySource is not even called back, when I would have expected it to be called with a poperty name of spring.cloud.stream.binders.my-binder.environment.spring.kafka.properties.ssl.truststore.location.
I think my PropertySource that would do the classpath: resolution is not part of the Environment of the given Spring Cloud Stream binder.
Question: how can one add PropertySources to a specific Binder's environment (or to all of them)?
Thanks!
EDIT
I add my PropertySource in a Spring Boot auto-configuration like this:
#Configuration
#AutoConfigureBefore(KafkaAutoConfiguration.class)
#ConditionalOnProperty(name = "com.acme.kafka.enabled", matchIfMissing = true)
#EnableConfigurationPropertiesAcmeKafkaConfigurations.class)
public class AcmeKafkaAutoConfiguration {
#Bean
ClasspathResourceSupportEnablingPropertySource acmeKafkaClasspathResourceEnablingPropertySource(ConfigurableEnvironment environment) throws IOException {
ClasspathResourcesSupport classpathResourcesSupport = new ClasspathResourcesSupport(Files.createTempDirectory(ACME_KAFKA_PREFIX));
ClasspathResourceSupportEnablingPropertySource propertySource
= new ClasspathResourceSupportEnablingPropertySource(ClasspathResourceSupportEnablingPropertySource.NAME, environment, classpathResourcesSupport);
environment.getPropertySources().addFirst(propertySource);
return propertySource;
}
}
EDIT NO.2: I tried out what Gary Russel suggested below (using a Bean Post Processor declared as a static bean method).
It works but in my case I get a lot of additional warning logs at startup of the form:
Bean '...' of type [...] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)
According to this post this can cause some really nasty side effects.
Here is the code I was using (which caused the warnings above):

How can I tell Spring to load only application-test.yml and not application.yml file ?
I have a config class:
#ActiveProfiles("test")
#SpringBootConfiguration
public class MongoTestConfig {
#Autowired
MongoOperations operations;
...
}
And a test class:
#RunWith(SpringRunner.class)
#DataMongoTest
#SpringBootTest(classes = MongoTestConfig.class)
public class TagDefinitionRepositoryTest {
...
#Test
....
}
I've tried to add :
#TestPropertySource(locations = {"classpath:application-test.yml"})
#ContextConfiguration(initializers = ConfigFileApplicationContextInitializer.class)
To my config class but it doesn't work: Spring still load application.yml
I don't think you can tell Spring Boot to ignore application.yml completely. What you can do though is to override all the non desired properties using test specific property files.
Based on the code snippet you posted, any property in application-test.yml will override the equivalent property in application.yml.
Spring Boot considers application-test.yml specific to the profile "test" (which has a higher priority over the default application.yml). No annotation #TestPropertySource is needed.
But if you want to choose another name for your properties file, then you can use #TestProertySource, since files indicated in #TestProperySource parameters have higher priority over the others.
You might want to have a look at Spring Boot external configuration rules for resolving properties
I've end up using #SpringBootTest instead of #DataMongoTest
#SpringBootConfiguration
#ComponentScan(basePackages = {"com.package.services"})
#EnableMongoRepositories(basePackages = {"com.package.repositories"})
public class MongoTestConfig {
private static final MongodStarter starter = MongodStarter.getDefaultInstance();
#Bean
public MongoClient mongoClient() throws IOException {
MongodExecutable _mongodExe;
MongodProcess _mongod;
_mongodExe = starter.prepare(new MongodConfigBuilder()
.version(Version.Main.V3_2)
.net(new Net("localhost", 12345, Network.localhostIsIPv6()))
.build());
_mongod = _mongodExe.start();
MongoClient _mongo = new MongoClient("localhost", 12345);
return _mongo;
}
#Bean
public MongoDbFactory mongoDbFactory() throws IOException{
return new SimpleMongoDbFactory(mongoClient() , "test");
}
#Bean
public MongoTemplate mongoTemplate() throws IOException {
return new MongoTemplate(mongoDbFactory());
}
And my test class is:
#RunWith(SpringRunner.class)
#SpringBootTest
public class MyRepositoryTest {
...
Suppose we start with an xml-based config, say main.xml, that imports a java config FullConfig.java via:
<context:annotation-config/>
<bean class="test.FullConfig"/>
This java config has the form:
#Configuration
#Import(value = {IncludeConfig.class})
public class FullConfig {
#Autowired
#Qualifier(value = "tmpBean")
private DataClazz autowired;
#Bean
public DataClazz someOtherBean() {
System.out.println("Using autowired tmpBean:" + autowired);
return new DataClazz();
}
}
so it imports a further java config, which contains a definition of the tmpBean of DataClazz type,
#Configuration
public class IncludeConfig {
#Bean
public DataClazz tmpBean() {
return new DataClazz();
}
}
Now two questions:
Is this "transitive inclusion" guaranteed to work in spring (i.e. is someOtherBean() guaranteed not to thrown a NPE)?
IntelliJ up to version 2017.2 does mark #Qualifier(value = "tmpBean") red with a message "Cannot find bean with qualifier 'tmpBean'". Should that be considered a bug?
Note: I have checked that an application using ClassPathXmlApplicationContext("main.xml") does work correctly, i.e. no NPE is thrown (and all relevant beans are visible).
You need to return DataClazz:
#Bean
public DataClazz someOtherBean() {
System.out.println("Using autowired tmpBean:" + autowired);
return autowired;
}
Probably yes but try to test it.
IDEA-82844 (Bug)
In my spring boot application, I have the main application.yml file. I have a lot of properties, and therefore I would like to have another yml files, which contains the specified properties, grouped by their logic or something.
How can I configure a Bean, to load and work all the properties from one new yml file, and another Bean from another new yml? What is the best practice for it?
I found examples using YamlPropertiesFactoryBean, and this bean can read several resources (yml files), but in an another Bean, when I autowire this YamlPropertiesFactoryBean, I cannot get that specific yml, because the getObject() of this YamlPropertiesFactoryBean will have all the yml resources I added to it.
Finally I have it! This is how it works:
I have a properties configuration class, which loads the yml files:
#Configuration
public class PropertiesConfig {
public static final String PERSONS_FILE_NAME = "persons.yml";
public static final String FOODS_FILE_NAME = "foods.yml";
#Bean
public PropertySourcesPlaceholderConfigurer properties() {
final PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
final YamlPropertiesFactoryBean personsYaml = personsPropertiesFromYamlFile();
final YamlPropertiesFactoryBean foodsYaml = foodsPropertiesFromYamlFile();
propertySourcesPlaceholderConfigurer.setPropertiesArray(personsYaml.getObject(), foodsYaml.getObject());
return propertySourcesPlaceholderConfigurer;
}
#Bean
#Qualifier(PersonsManager.QUALIFIER_NAME)
public YamlPropertiesFactoryBean personsPropertiesFromYamlFile() {
final YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
yaml.setResources(new ClassPathResource(PERSONS_FILE_NAME));
return yaml;
}
#Bean
#Qualifier(FoodsManager.QUALIFIER_NAME)
public YamlPropertiesFactoryBean foodsPropertiesFromYamlFile() {
final YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
yaml.setResources(new ClassPathResource(FOODS_FILE_NAME));
return yaml;
}
}
And finally, I have two beans (managers), which hold only the corresponding yml properties:
#Component
public class PersonsManager extends YmlPropertiesManager {
public static final String QUALIFIER_NAME = "personsYaml";
#Autowired
public PersonsManager(#Qualifier(QUALIFIER_NAME) YamlPropertiesFactoryBean yamlObject) {
super(yamlObject);
}
...
}
and:
#Component
public class FoodsManager extends YmlPropertiesManager {
public static final String QUALIFIER_NAME = "personsYaml";
#Autowired
public FoodsManager(#Qualifier(QUALIFIER_NAME) YamlPropertiesFactoryBean yamlObject) {
super(yamlObject);
}
...
}
So the main thing here is the #Qualifier annotation.
Beans shouldn't be aware of yaml files. The yaml files are just sources that use used to build up the Spring Environment instance.
If you want specific properties for specific beans, the best way is to prefix those properties in application.yaml, and then use the #ConfigurationProperties with an argument of the prefix you want to use, to bind those properties to the bean in question.
See here:
https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
Spring Boot allows us to replace our application.properties files with YAML equivalents. However, I seem to hit a snag with my tests. If I annotate my TestConfiguration (a simple Java config), it is expecting a properties file.
For example this doesn't work:
#PropertySource(value = "classpath:application-test.yml")
If I have this in my YAML file:
db:
url: jdbc:oracle:thin:#pathToMyDb
username: someUser
password: fakePassword
And I'd be leveraging those values with something like this:
#Value("${db.username}") String username
However, I end up with an error like so:
Could not resolve placeholder 'db.username' in string value "${db.username}"
How can I leverage the YAML goodness in my tests as well?
Spring-boot has a helper for this, just add
#ContextConfiguration(initializers = ConfigFileApplicationContextInitializer.class)
at the top of your test classes or an abstract test superclass.
Edit: I wrote this answer five years ago. It doesn't work with recent versions of Spring Boot. This is what I do now (please translate the Kotlin to Java if necessary):
#TestPropertySource(locations=["classpath:application.yml"])
#ContextConfiguration(
initializers=[ConfigFileApplicationContextInitializer::class]
)
is added to the top, then
#Configuration
open class TestConfig {
#Bean
open fun propertiesResolver(): PropertySourcesPlaceholderConfigurer {
return PropertySourcesPlaceholderConfigurer()
}
}
to the context.
As it was mentioned #PropertySource doesn't load yaml file. As a workaround load the file on your own and add loaded properties to Environment.
Implemement ApplicationContextInitializer:
public class YamlFileApplicationContextInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
#Override
public void initialize(ConfigurableApplicationContext applicationContext) {
try {
Resource resource = applicationContext.getResource("classpath:file.yml");
YamlPropertySourceLoader sourceLoader = new YamlPropertySourceLoader();
PropertySource<?> yamlTestProperties = sourceLoader.load("yamlTestProperties", resource, null);
applicationContext.getEnvironment().getPropertySources().addFirst(yamlTestProperties);
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}
Add your initializer to your test:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = Application.class, initializers = YamlFileApplicationContextInitializer.class)
public class SimpleTest {
#Test
public test(){
// test your properties
}
}
#PropertySource can be configured by factory argument. So you can do something like:
#PropertySource(value = "classpath:application-test.yml", factory = YamlPropertyLoaderFactory.class)
Where YamlPropertyLoaderFactory is your custom property loader:
public class YamlPropertyLoaderFactory extends DefaultPropertySourceFactory {
#Override
public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException {
if (resource == null){
return super.createPropertySource(name, resource);
}
return new YamlPropertySourceLoader().load(resource.getResource().getFilename(), resource.getResource(), null);
}
}

Another option is to set the spring.config.location through #TestPropertySource:
#TestPropertySource(properties = { "spring.config.location = classpath:<path-to-your-yml-file>" }
#PropertySource only supports properties files (it's a limitation from Spring, not Boot itself). Feel free to open a feature request ticket in JIRA.
From Spring Boot 1.4, you can use the new #SpringBootTest annotation to achieve this more easily (and to simplify your integration test setup in general) by bootstrapping your integration tests using Spring Boot support.
Details on the Spring Blog.
As far as I can tell, this means you get all the benefits of Spring Boot's externalized config goodness just like in your production code, including automatically picking up YAML config from the classpath.
By default, this annotation will
... first attempt to load #Configuration from any inner-classes, and if that fails, it will search for your primary #SpringBootApplication class.
but you can specify other configuration classes if required.
For this particular case, you can combine #SpringBootTest with #ActiveProfiles( "test" ) and Spring will pick up your YAML config, provided it follows the normal Boot naming standards (i.e. application-test.yml).
#RunWith( SpringRunner.class )
#SpringBootTest
#ActiveProfiles( "test" )
public class SpringBootITest {
#Value("${db.username}")
private String username;
#Autowired
private MyBean myBean;
...
}
Note: SpringRunner.class is the new name for SpringJUnit4ClassRunner.class
The approach to loading the yaml properties, IMHO can be done in two ways:
a. You can put the configuration in a standard location - application.yml in the classpath root - typically src/main/resources and this yaml property should automatically get loaded by Spring boot with the flattened path name that you have mentioned.
b. The second approach is a little more extensive, basically define a class to hold your properties this way:
#ConfigurationProperties(path="classpath:/appprops.yml", name="db")
public class DbProperties {
private String url;
private String username;
private String password;
...
}
So essentially this is saying that load the yaml file and populate the DbProperties class based on the root element of "db".
Now to use it in any class you will have to do this:
#EnableConfigurationProperties(DbProperties.class)
public class PropertiesUsingService {
#Autowired private DbProperties dbProperties;
}
Either of these approaches should work for you cleanly using Spring-boot.
Since Spring Boot 2.4.0 you can use ConfigDataApplicationContextInitializer as follows:
#SpringJUnitConfig(
classes = { UserAccountPropertiesTest.TestConfig.class },
initializers = { ConfigDataApplicationContextInitializer.class }
)
class UserAccountPropertiesTest {
#Configuration
#EnableConfigurationProperties(UserAccountProperties.class)
static class TestConfig { }
#Autowired
UserAccountProperties userAccountProperties;
#Test
void getAccessTokenExpireIn() {
assertThat(userAccountProperties.getAccessTokenExpireIn()).isEqualTo(120);
}
#Test
void getRefreshTokenExpireIn() {
assertThat(userAccountProperties.getRefreshTokenExpireIn()).isEqualTo(604800);
}
}
See also: https://www.baeldung.com/spring-boot-testing-configurationproperties#YAML-binding
I found a workaround by using #ActiveProfiles("test") and adding an application-test.yml file to src/test/resources.
It ended up looking like this:
#SpringApplicationConfiguration(classes = Application.class, initializers = ConfigFileApplicationContextInitializer.class)
#ActiveProfiles("test")
public abstract class AbstractIntegrationTest extends AbstractTransactionalJUnit4SpringContextTests {
}
The file application-test.yml just contains the properties that I want to override from application.yml (which can be found in src/main/resources).
I have tried all of the listed questions, but all of them not work for my task: using specific yaml file for some unit test.
In my case, it works like this:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(initializers = {ConfigFileApplicationContextInitializer.class})
#TestPropertySource(properties = {"spring.config.location=file:../path/to/specific/config/application.yml"})
public class SomeTest {
#Value("${my.property.value:#{null}}")
private String value;
#Test
public void test() {
System.out.println("value = " + value);
}
}
it's because you have not configure snakeyml.
spring boot come with #EnableAutoConfiguration feature.
there is snakeyml config too when u call this annotation..
this is my way:
#Configuration
#EnableAutoConfiguration
public class AppContextTest {
}
here is my test:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(
classes = {
AppContextTest.class,
JaxbConfiguration.class,
}
)
public class JaxbTest {
//tests are ommited
}
I needed to read some properties into my code and this works with spring-boot 1.3.0.RELEASE
#Autowired
private ConfigurableListableBeanFactory beanFactory;
// access a properties.yml file like properties
#Bean
public PropertySource properties() {
PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
YamlPropertiesFactoryBean yaml = new YamlPropertiesFactoryBean();
yaml.setResources(new ClassPathResource("properties.yml"));
propertySourcesPlaceholderConfigurer.setProperties(yaml.getObject());
// properties need to be processed by beanfactory to be accessible after
propertySourcesPlaceholderConfigurer.postProcessBeanFactory(beanFactory);
return propertySourcesPlaceholderConfigurer.getAppliedPropertySources().get(PropertySourcesPlaceholderConfigurer.LOCAL_PROPERTIES_PROPERTY_SOURCE_NAME);
}
Loading custom yml file with multiple profile config in Spring Boot.
1) Add the property bean with SpringBootApplication start up as follows
#SpringBootApplication
#ComponentScan({"com.example.as.*"})
public class TestApplication {
public static void main(String[] args) {
SpringApplication.run(TestApplication.class, args);
}
#Bean
#Profile("dev")
public PropertySourcesPlaceholderConfigurer propertiesStage() {
return properties("dev");
}
#Bean
#Profile("stage")
public PropertySourcesPlaceholderConfigurer propertiesDev() {
return properties("stage");
}
#Bean
#Profile("default")
public PropertySourcesPlaceholderConfigurer propertiesDefault() {
return properties("default");
}
/**
* Update custom specific yml file with profile configuration.
* #param profile
* #return
*/
public static PropertySourcesPlaceholderConfigurer properties(String profile) {
PropertySourcesPlaceholderConfigurer propertyConfig = null;
YamlPropertiesFactoryBean yaml = null;
propertyConfig = new PropertySourcesPlaceholderConfigurer();
yaml = new YamlPropertiesFactoryBean();
yaml.setDocumentMatchers(new SpringProfileDocumentMatcher(profile));// load profile filter.
yaml.setResources(new ClassPathResource("env_config/test-service-config.yml"));
propertyConfig.setProperties(yaml.getObject());
return propertyConfig;
}
}
2) Config the Java pojo object as follows
#Component
#JsonIgnoreProperties(ignoreUnknown = true)
#JsonInclude(Include.NON_NULL)
#ConfigurationProperties(prefix = "test-service")
public class TestConfig {
#JsonProperty("id")
private String id;
#JsonProperty("name")
private String name;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
3) Create the custom yml (and place it under resource path as follows,
YML File name : test-service-config.yml
Eg Config in the yml file.
test-service:
id: default_id
name: Default application config
---
spring:
profiles: dev
test-service:
id: dev_id
name: dev application config
---
spring:
profiles: stage
test-service:
id: stage_id
name: stage application config

Welcome to use my library. Now yaml, toml, hocon is supported.
Source: github.com
This is not an answer to the original question, but an alternative solution for a need to have a different configuration in a test...
Instead of #PropertySource you can use -Dspring.config.additional-location=classpath:application-tests.yml.
Be aware, that suffix tests does not mean profile...
In that one YAML file one can specify multiple profiles, that can kind of inherit from each other, read more here - Property resolving for multiple Spring profiles (yaml configuration)
Then, you can specify in your test, that active profiles (using #ActiveProfiles("profile1,profile2")) are profile1,profile2 where profile2 will simply override (some, one does not need to override all) properties from profile1.

I run this answer in my prod env!!! so if you against this ans. please test first!!!
There is no need to add like YamlPropertyLoaderFactory or YamlFileApplicationContextInitializer. You should convert your idea
Follow these steps:
Just add applicationContext.xml like
#ImportResource({"classpath:applicationContext.xml"})
to your ApplicationMainClass.
and your applicationContext.xml should write like this
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
default-autowire="byName"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<context:property-placeholder location="classpath*:*.yml"/>
</beans>
This can help scan your application-test.yml
db:
url: jdbc:oracle:thin:#pathToMyDb

password: fakePassword
Enhancing Mateusz Balbus answer.
Modified YamlFileApplicationContextInitializer class where YAML location is defined per test class. It does not work per test, unfortunately.
public abstract class YamlFileApplicationContextInitializer
implements ApplicationContextInitializer<ConfigurableApplicationContext> {
/***
* Return location of a YAML file, e.g.: classpath:file.yml
*
* #return YAML file location
*/
protected abstract String getResourceLocation();
#Override
public void initialize(ConfigurableApplicationContext applicationContext) {
try {
Resource resource = applicationContext.getResource(getResourceLocation());
YamlPropertySourceLoader sourceLoader = new YamlPropertySourceLoader();
PropertySource<?> yamlTestProperties = sourceLoader.load("yamlTestProperties", resource, null);
applicationContext.getEnvironment().getPropertySources().addFirst(yamlTestProperties);
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}
Usage:
Create subclass of YamlFileApplicationContextInitializer with defined getResourceLocation() method and add this subclass into #SpringApplicationConfiguration annotation.
This way it is easiest to make the test class itself.
#RunWith(SpringRunner.class)
#SpringApplicationConfiguration(classes = Application.class, initializers = SimpleTest.class)
public class SimpleTest extends YamlFileApplicationContextInitializer {
#Override
protected String getResourceLocation() {
return "classpath:test_specific.yml";
}
#Test
public test(){
// test your properties
}
}
Here's an improved version of YamlPropertyLoaderFactory which supports the new PropertySource.ignoreResourceNotFound, based on this answer:
Java:
public final class YamlPropertyLoaderFactory extends DefaultPropertySourceFactory {
private final YamlPropertySourceLoader yamlPropertySourceLoader = new YamlPropertySourceLoader();
#NotNull
public PropertySource createPropertySource(
#Nullable String name,
#NotNull EncodedResource resource
) {
try {
String parsedName;
if (name != null && !name.equals(""))
parsedName = name;
else parsedName = resource.getResource().getFilename();
return yamlPropertySourceLoader.load(parsedName, resource.getResource()).get(0);
} catch (Exception e) {
Exception possibleFileNotFoundException = ExceptionUtils.throwableOfType(e, FileNotFoundException.class);
throw possibleFileNotFoundException != null ? possibleFileNotFoundException : e;
}
}
}
// Usage
#PropertySource(
value = {"file:./my-optional-config.yml"},
factory = YamlPropertyLoaderFactory.class,
ignoreResourceNotFound = true
)
Kotlin:
class YamlPropertyLoaderFactory : DefaultPropertySourceFactory() {
private val yamlPropertySourceLoader = YamlPropertySourceLoader()
override fun createPropertySource(
name: String?,
resource: EncodedResource
): PropertySource<*> = try {
(
yamlPropertySourceLoader.load(
if (name != null && name.isNotBlank()) name else resource.resource.filename,
resource.resource
)
)[0]
} catch (e: Exception) {
throw ExceptionUtils.throwableOfType(e, FileNotFoundException::class.java) ?: e
}
}
// Usage
#PropertySource(
value = ["file:/my-optional-config.yml"],
factory = YamlPropertyLoaderFactory::class,
ignoreResourceNotFound = true
)
