I have created a simple spring application to test excludeFilters in #ComponentScan annotation.
TestConfig.java
package com.example.config;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.FilterType;
import org.springframework.stereotype.Controller;
#Configuration
#ComponentScan(
excludeFilters = #ComponentScan.Filter(
type = FilterType.REGEX,
pattern = {"com.example.Demo"}
)
)
public class TestConfig {
}
Demo.java
package com.example;
import org.springframework.stereotype.Component;
#Component
public class Demo {
}
Main class ExcludeFilterTest.java
public class ExcludeFilterTest {
public static void main(String[] args) {
ApplicationContext applicationContext = new AnnotationConfigApplicationContext("com.example");
}
}
when running the application I can see the Demo class is getting identified as a candidate component class and also instance is getting created.
here are the logs
12:05:34.151 [main] DEBUG org.springframework.context.annotation.ClassPathBeanDefinitionScanner - Identified candidate component class: file [/Users/sk/learning-development/interview/logging_test/target/classes/com/example/Demo.class]

Process finished with exit code 0
why the Demo class instance is getting created?
Try this instead.
public class ExcludeFilterTest {
public static void main(String[] args) {
ApplicationContext applicationContext = new AnnotationConfigApplicationContext(com.example.config.TestConfig.class);
}
}
This question already has an answer here:
Karate Spring Integration
(1 answer)
Closed 1 year ago.
We have a Spring Boot project which uses an application.yml file to configure the spring context for things like datasource, rabbitmq etc.
The YAML file can be loaded in the karate-config.js to pick-up the baseUrl and that works fine.
function fn() {
var env = karate.env; // get system property 'karate.env'
karate.log('karate.env system property was:', env);
if (!env) {
env = 'dev';
}
karate.log('karate environment set to:', env);
var config = karate.read('classpath:application.yml');
karate.log('baseUrl configured for API tests: '+config.baseUrl)
if (env == 'dev') {
var Factory = Java.type('MockSpringMvcServlet');
karate.configure('httpClientInstance', Factory.getMock());
//var result = karate.callSingle('classpath:demo/headers/common-noheaders.feature', config);
} else if (env == 'stg') {
// customize
} else if (env == 'prod') {
// customize
}
return config;
}
The Mock Spring MVC servlet class taken from the karate mock servlet demo github project:
/**
* #author pthomas3
*/
public class MockSpringMvcServlet extends MockHttpClient {
private final Servlet servlet;
private final ServletContext servletContext;
public MockSpringMvcServlet(Servlet servlet, ServletContext servletContext) {
this.servlet = servlet;
this.servletContext = servletContext;
}
#Override
protected Servlet getServlet(HttpRequestBuilder request) {
return servlet;
}
#Override
protected ServletContext getServletContext() {
return servletContext;
}
private static final ServletContext SERVLET_CONTEXT = new MockServletContext();
private static final Servlet SERVLET;
static {
SERVLET = initServlet();
}
private static Servlet initServlet() {
AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
context.register(MockConfig.class);
context.setServletContext(SERVLET_CONTEXT);
DispatcherServlet servlet = new DispatcherServlet(context);
ServletConfig servletConfig = new MockServletConfig();
try {
servlet.init(servletConfig);
} catch (Exception e) {
throw new RuntimeException(e);
}
return servlet;
}
public static MockSpringMvcServlet getMock() {
return new MockSpringMvcServlet(SERVLET, SERVLET_CONTEXT);
}
}
However, the MockConfig.class fails on the EnableAutoConfiguration annotation:
#Configuration
#EnableAutoConfiguration
// #PropertySource("classpath:application.yml") // only for key/value pair .properties files and not YAML
public class MockConfig {
// Global Exception Handler ...
// Services ...
// Controllers ...
#Bean
public NumbersAPI numbersAPI() {
return new NumbersAPI();
}
}
The exception is:

I've used the documentation from the karate mock-servlet github project as guidance to make other karate tests work successfully, but I don't know how to configure the spring context for our karate tests using an application YAML file.
The #PropertySource only supports properties files as you already found out.
Have a look at the following SOF question:
Spring #PropertySource using YAML
Hope this helps.
I was able to get the application.yml file to be respected and loaded by Spring by making the following changes:
Add a YamlPropertySourceFactory util class to the test package:
import org.springframework.beans.factory.config.YamlPropertiesFactoryBean;
import org.springframework.core.env.PropertiesPropertySource;
import org.springframework.core.env.PropertySource;
import org.springframework.core.io.support.EncodedResource;
import org.springframework.core.io.support.PropertySourceFactory;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Properties;
public class YamlPropertySourceFactory implements PropertySourceFactory {
#Override
public PropertySource<?> createPropertySource(String name, EncodedResource resource) throws IOException {
Properties propertiesFromYaml = loadYamlIntoProperties(resource);
String sourceName = name != null ? name : resource.getResource().getFilename();
return new PropertiesPropertySource(sourceName, propertiesFromYaml);
}
private Properties loadYamlIntoProperties(EncodedResource resource) throws FileNotFoundException {
try {
YamlPropertiesFactoryBean factory = new YamlPropertiesFactoryBean();
factory.setResources(resource.getResource());
factory.afterPropertiesSet();
return factory.getObject();
} catch (IllegalStateException e) {
// for ignoreResourceNotFound
Throwable cause = e.getCause();
if (cause instanceof FileNotFoundException)
throw (FileNotFoundException) e.getCause();
throw e;
}
}
}
and
Referencing the above in the #PropertySource annotation in the MockConfig class as follows:
#Configuration
#EnableAutoConfiguration
#PropertySource(factory = YamlPropertySourceFactory.class, value = "classpath:application.yml")
public class MockConfig {
// Global Exception Handler ...
#Bean
public ExampleAPIExceptionHandler exampleAPIExceptionHandler() {
return new ExampleAPIExceptionHandler();
}
// Services ...
// Controllers ...
#Bean
public NumbersAPI numbersAPI() {
return new NumbersAPI();
}
}
The Spring context loads and all karate tests pass.
If there is a simpler way to load a YAML file as a Spring context using Karate, then please post it. For now, this will work.
Reference: Use #PropertySource with YAML files
I have a spring batch written using Spring boot. My batch only reads from MongoDB and prints the record.
I'm not using any SQL DB nor have any dependencies declared in project but While running it I'm getting below exception:

Consider revisiting the conditions above or defining a bean of type 'javax.sql.DataSource' in your configuration.
In my pom.xml I've added below dependancies:
spring-boot-starter-batch
spring-boot-starter-data-mongodb
spring-boot-starter-test
spring-batch-test
Here's my batch configuration class:
#Configuration
#EnableBatchProcessing
public class BatchConfig {
#Autowired
private JobBuilderFactory jobBuilderFactory;
#Autowired
private StepBuilderFactory stepBuilderFactory;
#Autowired
private MongoTemplate mongoTemplate;
#Bean
public Job job() throws Exception {
return jobBuilderFactory.get("job1").flow(step1()).end().build();
}
#Bean
public Step step1() throws Exception {
return stepBuilderFactory.get("step1").<BasicDBObject, BasicDBObject>chunk(10).reader(reader())
.writer(writer()).build();
}
#Bean
public ItemReader<BasicDBObject> reader() {
MongoItemReader<BasicDBObject> reader = new MongoItemReader<BasicDBObject>();
reader.setTemplate(mongoTemplate);
reader.setCollection("test");
reader.setQuery("{'status':1}");
reader.setSort(new HashMap<String, Sort.Direction>() {
{
put("_id", Direction.ASC);
}
});
reader.setTargetType((Class<? extends BasicDBObject>) BasicDBObject.class);
return reader;
}
public ItemWriter<BasicDBObject> writer() {
MongoItemWriter<BasicDBObject> writer = new MongoItemWriter<BasicDBObject>();
return writer;
}
}
Here's is my launcher class:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
#SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class MyBatchApplication {
...
}
Spring Batch requires the use of a relational data store for the job repository. Spring Boot enforces that fact. In order to fix this, you'll need to add an in memory database or create your own BatchConfigurer that uses the Map based repository. For the record, the recommended approach is to add an in memory database (HSQLDB/H2/etc).
I have a bean, which implements ServletContextAware and BeanFactoryPostProcessor interfaces. I need this this bean register into the applicationContext after the ServletContext finished initialization, because I use some parameters in the servletContext to init this bean.
I am using the Spring Boot, the bean name is SpringBeanProcessorServletAware. I have add it into a configuration bean.
#Bean
public static SpringBeanProcessorServletAware springBeanProcessor() {
SpringBeanProcessorServletAware p = new SpringBeanProcessorServletAware();
return p;
}
My issue is that the bean is created before my container set servletContext to it. Then I can't get the parameters from the servletContext. How to control that the bean must be created after my servletContext has been created completely?
Really need help. I used JUnit(4.6) plus Spring(3.0.5) for unit testing. When I tried to autowire a service object in my test class, I got a NoSuchBeanDefinitionException.
The JUnit code:
package com.aaa.service.impl;
#ContextConfiguration(locations = { "classpath:/spring/applicationContext.xml",
"classpath:/spring/applicationContext-aop.xml",
"classpath:/spring/applicationContext-dao.xml",
"classpath:/spring/applicationContext-service.xml" })
#RunWith(SpringJUnit4ClassRunner.class)
public class TestManageTargetServiceImpl {
#Autowired
ManageTargetServiceImpl manageTargetServiceImpl;
#Test
public void testQueryFinancialMonthList() {
List<Map<String, Object>> value = new ArrayList<Map<String, Object>>();
ManageTargetDao manageTargetDao = mock(ManageTargetDao.class);
when(manageTargetDao.queryFinancialMonthList()).thenReturn(value);
manageTargetServiceImpl.setManageTargetDao(manageTargetDao);
// I hope it return null
assertNull(manageTargetServiceImpl.queryFinancialMonthList());
}
}
The applicationContext-service.xml code:
<context:annotation-config />
<bean id="manageTargetService" class="com.aaa.service.impl.ManageTargetServiceImpl">
<property name="manageTargetDao" ref="manageTargetDao"></property>
</bean>

Guessing here - but given that injection of a class type ManageTargetServiceImpl is failing, I think the reason is that a proxy is getting created for ManageTargetServiceImpl and so the type of the bean will not be ManageTargetServiceImpl anymore but the interface of that class.

Look at your property id. It should be manageTargetServiceImpl in your applicationContext-service.xml
Change it to this:
<bean id="manageTargetServiceImpl" class="com.aaa.service.impl.ManageTargetServiceImpl">
<property name="manageTargetDao" ref="manageTargetDao"></property>
</bean>
