With Spring Boot 1.x, we could specify hibernate mapping files by extending HibernateJpaAutoConfiguration, overriding LocalContainerEntityManagerFactoryBean bean and set mapping resources, like in this answer.
Since Spring Boot 2.0 (2.0.0.M5 precisly), we can’t do this anymore because HibernateJpaAutoConfiguration has changed (with this commit) and we can’t extend the HibernateJpaConfiguration because it is package protected.
Do you know another way to specify hibernate mapping files using Spring Boot 2.0?
Thanks!
Since Spring Boot 2.0.0.M6, rather than overriding Spring Boot's internal, you should use the new spring.jpa.mapping-resources property for defining custom mappings.
Example in YML:
spring:
jpa:
mapping-resources:
- db/mappings/dummy.xml
For a complete example, check the application.yml configuration file of this repository.
private String[] loadResourceNames() {
Resource[] resources = null;
List<String> names = new ArrayList<String>();
try {
resources = ResourcePatternUtils.getResourcePatternResolver(resourceLoader).getResources("classpath: *.hbm.xml");
for ( Resource resource : resources ) {
names.addAll( Files.list( resource.getFile().toPath() )
.map ( path -> path.getFileName().toString() )
.filter ( p -> p.endsWith( "hbm.xml") )
.map ( p -> "your directory on class path".concat(p) )
.collect ( Collectors.toList() ) );
}
}catch(IOException e){
e.printStackTrace();
}
System.out.println(resources);
return names.toArray(new String[names.size()]);
}

Spring boot auto configures RedisConnectionFactory if spring-data-redis exists on classpath and RedisConnectionFactory is initialized in LettuceConnectionConfiguration if Lettuce-core available on classpath.
I've only one Redis store as of now, so leveraging Spring boot auto configuration.
Now I'm adding two redis stores, one redis store used as default and other is used when specified with parameter cacheManager = "secondayCacheManager" in #Cacheable annotation so, application should've capability to cache/cache-get on both redis stores.
To configure both Redis Stores, we've to configure both the primary and secondary RedisConnectionFactory and cacheManager using custom configuration. (because spring doesn't auto configure RedisConnectionFactory if it already exists in any custom configuration)
Now the above is custom configuration and missing lot of logic that is happening while configuring RedisConnectionFactory in LettuceConnectionConfiguration.
Auto configure logic for LettuceConnectionConfiguration is package private so, cannot be called directly from custom configuration.
We would like to leverage the auto configure logic in
LettuceConnectionConfiguration while configuring the custom
RedisConnectionFactory for both primary and secondary redis caches.
Is there a way to achieve this?
Reason being we would like keep the redis connection configurations as it is done by spring boot auto configure.
Currently using below code to configure both the primary and secondary RedisConnectionFactory with Pool configuration and some code copy pasted from LettuceConnectionConfiguration class.
public static LettuceConnectionFactory buildLettuceConnectionFactory(RedisProperties properties, ClientResources clientResources) {
RedisStandaloneConfiguration standaloneConfiguration = new RedisStandaloneConfiguration(properties.getHost(), properties.getPort());
standaloneConfiguration.setDatabase(properties.getDatabase());
if (properties.getPassword() != null) {
standaloneConfiguration.setPassword(RedisPassword.of(properties.getPassword()));
}
if (properties.getUsername() != null) {
standaloneConfiguration.setUsername(properties.getUsername());
}
LettucePoolingClientConfiguration poolingClientConfiguration = LettucePoolingClientConfiguration.builder()
.poolConfig(buildGenericObjectPoolConfig(properties))
.shutdownTimeout(properties.getLettuce().getShutdownTimeout())
.clientOptions(createClientOptions(properties))
.clientResources(clientResources)
.build();
LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(
standaloneConfiguration, poolingClientConfiguration);
lettuceConnectionFactory.afterPropertiesSet();
return lettuceConnectionFactory;
}
private static GenericObjectPoolConfig buildGenericObjectPoolConfig(RedisProperties properties) {
RedisProperties.Pool pool = properties.getLettuce().getPool();
GenericObjectPoolConfig poolConfig = new GenericObjectPoolConfig();
if (Objects.nonNull(pool)) {
poolConfig.setMaxIdle(pool.getMaxIdle());
poolConfig.setMinIdle(pool.getMinIdle());
poolConfig.setMaxTotal(pool.getMaxActive());
poolConfig.setMaxWaitMillis(pool.getMaxWait().toMillis());
}
return poolConfig;
}
private static ClientOptions createClientOptions(RedisProperties properties) {
ClientOptions.Builder builder = initializeClientOptionsBuilder(properties);
Duration connectTimeout = properties.getConnectTimeout();
if (connectTimeout != null) {
builder.socketOptions(SocketOptions.builder().connectTimeout(connectTimeout).build());
}
return builder.timeoutOptions(TimeoutOptions.enabled()).build();
}
private static ClientOptions.Builder initializeClientOptionsBuilder(RedisProperties properties) {
if (properties.getCluster() != null) {
ClusterClientOptions.Builder builder = ClusterClientOptions.builder();
Refresh refreshProperties = properties.getLettuce().getCluster().getRefresh();
Builder refreshBuilder = ClusterTopologyRefreshOptions.builder()
.dynamicRefreshSources(refreshProperties.isDynamicRefreshSources());
if (refreshProperties.getPeriod() != null) {
refreshBuilder.enablePeriodicRefresh(refreshProperties.getPeriod());
}
if (refreshProperties.isAdaptive()) {
refreshBuilder.enableAllAdaptiveRefreshTriggers();
}
return builder.topologyRefreshOptions(refreshBuilder.build());
}
return ClientOptions.builder();
}
While trying to use listener config properties in application.yml, I am facing an issue where the KafkaListener annotated method is not invoked at all if I use the application.yml config(listener.type= batch). It only gets invoked when I explicitly set setBatchListener to true in code. Here is my code and configuration.
Consumer code:
#KafkaListener(containerFactory = "kafkaListenerContainerFactory",
topics = "${spring.kafka.template.default-topic}",
groupId = "${spring.kafka.consumer.group-id}")
public void receive(List<ConsumerRecord<String,byte[]>> consumerRecords,Acknowledgment acknowledgment){
processor.process(consumerRecords,acknowledgment);
}
application.yml:
listener:
missing-topics-fatal: false
type: batch
ack-mode: manual
Consumer configuration:
ConcurrentKafkaListenerContainerFactory<String, String> factory =
new ConcurrentKafkaListenerContainerFactory<>();
factory.setConsumerFactory(
new DefaultKafkaConsumerFactory<>(kafkaProperties.buildConsumerProperties()));
factory.setErrorHandler(new SeekToCurrentErrorHandler( new UpdateMessageErrorHandler(),new FixedBackOff(idleEventInterval,maxFailures)));
final ContainerProperties properties = factory.getContainerProperties();
properties.setIdleBetweenPolls(idleBetweenPolls);
properties.setIdleEventInterval(idleEventInterval);
return factory;
}
If I'm not mistaken, by using the ConcurrentKafkaListenerContainerFactory builder in your configuration you're essentially overriding a piece of code that is usually executed within ConcurrentKafkaListenerContainerFactoryConfigurer class within spring autoconfiguration package:
if (properties.getType().equals(Type.BATCH)) {
factory.setBatchListener(true);
factory.setBatchErrorHandler(this.batchErrorHandler);
} else {
factory.setErrorHandler(this.errorHandler);
}
Since it's hardcoded in your application.yaml file anyway, why is it a bad thing for it to be configured in your #Configuration file?
So I want this to work
#Bean
#ConfigurationProperties("datasource.mybatis-factory")
public SqlSessionFactoryBean sqlSessionFactoryBean() {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());
return sqlSessionFactoryBean;
}
with property (among others)
datasource.mybatis-factory.mapper-locations=classpath*:sqlmap/*.xml
However, it fails even though the files are there:
Caused by: java.io.FileNotFoundException: class path resource [classpath*:sqlmap/*.xml] cannot be opened because it does not exist
Looking at setMapperLocations() I didn't do anything wrong, they clearly want me to use classpath*:...:
/**
* Set locations of MyBatis mapper files that are going to be merged into the {#code SqlSessionFactory} configuration
* at runtime.
*
* This is an alternative to specifying "<sqlmapper>" entries in an MyBatis config file. This property being
* based on Spring's resource abstraction also allows for specifying resource patterns here: e.g.
* "classpath*:sqlmap/*-mapper.xml".
*
* #param mapperLocations
* location of MyBatis mapper files
*/
public void setMapperLocations(Resource... mapperLocations) {
this.mapperLocations = mapperLocations;
}
Looking further down the code there's just this:
for (Resource mapperLocation : this.mapperLocations) {
if (mapperLocation == null) {
continue;
}
try {
XMLMapperBuilder xmlMapperBuilder = new XMLMapperBuilder(mapperLocation.getInputStream(),
targetConfiguration, mapperLocation.toString(), targetConfiguration.getSqlFragments());
xmlMapperBuilder.parse();
There is no code that would convert the classpath*:sqlmap/*.xml into openable resources or at least I don't see it. Or what am I missing here?
Work around:
What I have now and is working (note that I don't use datasource.mybatis-factory.mapper-locations as that would again overwrite what I set):
#Bean
#ConfigurationProperties("datasource.mybatis-factory")
public SqlSessionFactoryBean sqlSessionFactoryBean(
#Value("${datasource.mybatis-factory.mapper-location-pattern}") String mapperLocations) {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());
sqlSessionFactoryBean.setMapperLocations(findMapperLocations(mapperLocations));
return sqlSessionFactoryBean;
}
private Resource[] findMapperLocations(String resourcePaths) {
PathMatchingResourcePatternResolver patternResolver = new PathMatchingResourcePatternResolver();
return Stream.of(resourcePaths.split(","))
.map(LambdaExceptionUtilities.rethrowFunction(patternResolver::getResources))
.flatMap(Stream::of)
.toArray(Resource[]::new);
}
with property
datasource.mybatis-factory.mapper-location-pattern=classpath*:sqlmap/*.xml
So: what is missing here to make it work without the work around? How do XMLs on the classpath find the way into MyBatis? Maybe something Spring-Bootish missing?
I ran into the same issue recently. I believe this is what what you're looking for:
#Bean
#ConfigurationProperties("datasource.mybatis-factory")
public SqlSessionFactoryBean sqlSessionFactoryBean(
#Value("${datasource.mybatis-factory.mapper-location-pattern}") String mapperLocations) {
SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
sqlSessionFactoryBean.setDataSource(dataSource());
sqlSessionFactoryBean.setMapperLocations(
new PathMatchingResourcePatternResolver().getResources("classpath*:sqlmap/*.xml")
);
return sqlSessionFactoryBean;
}
Basically what you need is this line of code in your #Bean definition above:
sqlSessionFactoryBean.setMapperLocations( new PathMatchingResourcePatternResolver().getResources("classpath*:sqlmap/*.xml")
);
Note: the method name is getResources (the plural) and not getResource
Feel free to replace the hard coded value of classpath*:sqlmap/*.xml with the #Value("datasource.mybatis-factory.mapper-location-pattern") injected value instead.
Because you're using MyBatis with Spring, the issue here is not so much a MyBatis issue, as much as it is a Spring issue. More specifically, the wildcard feature that you want to use to load multiple resources, namely, classpath*:sqlmap/*.xml is specific to Spring and not MyBatis.
I know, that the way it's documented in the MyBatis-Spring docs may lead you to believe that it's a MyBatis feature that let's you do this type of wildcard Resource loading, but it's not. Here's the relevant part of the MyBatis-Spring doc (source: https://mybatis.org/spring/factorybean.html#properties):
The mapperLocations property takes a list of resource locations. This property can be used to specify the location of MyBatis XML mapper files. The value can contain Ant-style patterns to load all files in a directory or to recursively search all paths from a base location.
However, sadly the docs only provide a Spring example based on XML and not Java configuration. If you read the Java Docs docs for SqlSessionFactoryBean, you'll find the following (source: https://mybatis.org/spring/apidocs/org/mybatis/spring/SqlSessionFactoryBean.html#setMapperLocations(org.springframework.core.io.Resource...)):
public void setMapperLocations(org.springframework.core.io.Resource... mapperLocations)
Set locations of MyBatis mapper files that are going to be merged into the
SqlSessionFactory configuration at runtime.
This is an alternative to specifying "<sqlmapper>" entries in an MyBatis config file.
This property being based on Spring's resource abstraction also allows for
specifying resource patterns here: e.g. "classpath*:sqlmap/*-mapper.xml".
Parameters:
mapperLocations - location of MyBatis mapper files
So, the setMapperLocations method needs one or more org.springframework.core.io.Resource object(s). So, using Spring ClassPathResource will not work here because ClassPathResource expects only a single resource. What you need to use instead is Spring's PathMatchingResourcePatternResolver class. See: https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/core/io/support/PathMatchingResourcePatternResolver.html
You may also find this Stack Overflow post useful: How to use wildcards when searching for resources in Java-based Spring configuration?
I hope this helps!
your property should be like this.
if you use default configuration,
mybatis.mapper-locations: classpath*:sqlmap/**/*.xml
if you use your own as you mention above,
datasource.mybatis-factory.mapper-locations= classpath*:sqlmap/**/*.xml
this is a working example code, you can get an idea from this.
#Configuration
#MapperScans(
{
#MapperScan(
basePackages = {"com.example.seeker.repository"},
sqlSessionFactoryRef = "sqlSessionFactorySeeker",
sqlSessionTemplateRef = "sqlSessionTemplateSeeker"
)
}
)
public class SeekerDataSourceConfig {
#Autowired
Environment environment;
#Bean(value = "dsSeeker")
#ConfigurationProperties(prefix = "spring.datasource.seeker")
DataSource dsSeeker() {
return DataSourceBuilder.create().build();
}
#Qualifier("dsSeeker")
#Autowired
private DataSource dsSeeker;
#Bean(value = "sqlSessionFactorySeeker")
public SqlSessionFactory sqlSessionFactorySeeker() {
SqlSessionFactory sessionFactory = null;
try {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
PathMatchingResourcePatternResolver pathM3R = new PathMatchingResourcePatternResolver();
bean.setMapperLocations(pathM3R.getResources("classpath*:sqlmap/**/*.xml"));
bean.setDataSource(dsSeeker);
sessionFactory = bean.getObject();
} catch (Exception e) {
e.printStackTrace();
}
return sessionFactory;
}
#Bean(value = "sqlSessionTemplateSeeker")
public SqlSessionTemplate sqlSessionTemplateSeeker() {
return new SqlSessionTemplate(sqlSessionFactorySeeker());
}
#Bean(name = StaticResource.TxManager.TX_MANAGER_SEEKER)
public PlatformTransactionManager txManager() {
return new DataSourceTransactionManager(dsSeeker);
}
}
property file

spring.datasource.seeker.password=ewfky4eyrmggxbw6**
spring.datasource.seeker.driver-class-name=com.mysql.cj.jdbc.Driver
if you want to using with yml file you can add in the following path your application.yml file
mybatis:
mapperLocations: classpath:sql/*.xml
config-location: classpath:config/mybatis.xml
I configure my JAXRS Server in Spring Boot like so:
JAXRSServerFactoryBean factoryBean = new JAXRSServerFactoryBean();
factoryBean.setBus(this.bus);
factoryBean.setFeatures(singletonList(swagger2Feature()));
factoryBean.setServiceBeans(Arrays.asList(blah(), blah2(), blah3()));
factoryBean.setAddress("/api/v1/"); // HERE
List<Object> providers = new ArrayList<>();
providers.add(new JacksonJaxbJsonProvider());
factoryBean.setProviders(providers);
BindingFactoryManager manager = factoryBean.getBus().getExtension(BindingFactoryManager.class);
JAXRSBindingFactory restFactory = new JAXRSBindingFactory();
restFactory.setBus(factoryBean.getBus());
manager.registerBindingFactory(JAXRSBindingFactory.JAXRS_BINDING_ID, restFactory);
return factoryBean.create();
However, the URLs always require /services in front, which is a nuisance (but not the end of the world). Is there any way I can remove /services and just get it deployed to the root context?
If you have not created your own CxfServlet bean you can set the path by setting cxf.path property in your application.properties file
cxf.path=/
Another way is to override ServletRegistrationBean.
#Bean
public ServletRegistrationBean cxfServletRegistration() {
String urlMapping = "/*";
ServletRegistrationBean registration = new ServletRegistrationBean(
new CXFServlet(), urlMapping);
registration.setLoadOnStartup(-1);
return registration;
}
I'm using Spring Cloud Config in my spring-boot application and I need to write some custom code to handle properties to be read from my corporate password vault when property is flagged as such. I know spring cloud supports Hashicorp Vault, but that's not the one in case.
I don't want to hard-code specific properties to be retrieved from a different source, for example, I would have a properties file for application app1 with profile dev with values:
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=dbuser
spring.datasource.password=dbpass
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
but for some other profiles such as prod, I would have:
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=prod-user
spring.datasource.password=[[vault]]
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
So I need the custom property vault to intercept the property loaded whenever it finds a returned value equals to [[vault]] (or some other type of flag), and query from the corporate vault instead. In this case, my custom property loader would find the value of property spring.datasource.password from the corporate password vault. All other properties would still be returned as-is from values loaded by standard spring cloud config client.
I would like to do that using annotated code only, no XML configuration.
You can implement your own PropertySourceLocator and add entry to
spring.factories in directory META-INF.
#spring.factories
org.springframework.cloud.bootstrap.BootstrapConfiguration=/
foo.bar.MyPropertySourceLocator
Then you can you can refer to keys in your corporate password vault like a normal properties in spring.
spring.datasource.url=jdbc:mysql://localhost/test
spring.datasource.username=prod-user
spring.datasource.password=${lodaded.password.from.corporate.vault}
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
Implementation by HasiCorp: VaultPropertySourceLocatorSupport
While trying to solve the identical problem, I believe that I have come to work-around that may be acceptable.
Here is my solution below.
public class JBossVaultEnvironmentPostProcessor implements EnvironmentPostProcessor {
#Override
public void postProcessEnvironment(ConfigurableEnvironment environment, SpringApplication application) {
MutablePropertySources propertySources = environment.getPropertySources();
Map<String, String> sensitiveProperties = propertySources.stream()
.filter(propertySource -> propertySource instanceof EnumerablePropertySource)
.map(propertySource -> (EnumerablePropertySource<?>) propertySource)
.map(propertySource -> {
Map<String, String> vaultProperties = new HashMap<>();
String[] propertyNames = propertySource.getPropertyNames();
for (String propertyName : propertyNames) {
String propertyValue = propertySource.getProperty(propertyName).toString();
if (propertyValue.startsWith("VAULT::")) {
vaultProperties.put(propertyName, propertyValue);
}
}
return vaultProperties;
})
.reduce(new HashMap<>(), (m1, m2) -> {
m1.putAll(m2);
return m1;
});
Map<String, Object> vaultProperties = new HashMap<>();
sensitiveProperties.keySet().stream()
.forEach(key -> {
vaultProperties.put(key, VaultReader.readAttributeValue(sensitiveProperties.get(key)));
});
propertySources.addFirst(new MapPropertySource("vaultProperties", vaultProperties));
}
