Given a class:
class MyConfiguration {
@Bean
String bean() {
return new String();
}
}
as you may notice it does not have @Configuration
annotation.
How can I make it behave like it has @Configuration
annotation, but not adding it?
@Bean
annotation should not work in Lite Mode
, https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/context/annotation/Bean.html
Something like:
@Configuration
class MainConfiguration {
@Bean
MyConfiguration myConfiguration() {
MyConfiguration myConfiguration = do_some_spring_magic();
// myConfiguration behaving like it's having @Configuration here
return myConfiguration;
}
}
I dont understand what is the use case you are trying to achieve here.. But if you are looking for programatically registering beans into the Spring Context then you can do it as below.
@Configuration
public class MyBeanRegisterFactory implements BeanDefinitionRegistryPostProcessor, PriorityOrdered {
@Override
public void postProcessBeanDefinitionRegistry(BeanDefinitionRegistry beanRegistry) throws BeansException {
//depending on some condition you can do the below line
beanRegistry.registerBeanDefinition("myBeanClass", new RootBeanDefinition("com.mybean.MyBeanClass"));
}
@Override
public int getOrder() {
return Ordered.HIGHEST_PRECEDENCE;
}
}
In Your case, the bean definitions inside the class MyConfiguration can be programatically registered as below into to the spring context.
