Package io.microsphere.spring.context.annotation

Class BeanCapableImportCandidate

  • All Implemented Interfaces:
    org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.context.EnvironmentAware, org.springframework.context.ResourceLoaderAware
    Direct Known Subclasses:
    AnnotatedPropertySourceLoader
    public abstract class BeanCapableImportCandidate
extends java.lang.Object
implements org.springframework.beans.factory.BeanClassLoaderAware, org.springframework.beans.factory.BeanFactoryAware, org.springframework.context.EnvironmentAware, org.springframework.context.ResourceLoaderAware
    The @Import candidate is an instance of ImportSelector or ImportBeanDefinitionRegistrar and not a regular Spring bean, which only invokes BeanClassLoaderAware, BeanFactoryAware, EnvironmentAware, and ResourceLoaderAware contracts in order if they are implemented, thus it will not be populated and initialized .

    The current abstract implementation is a template class supports the Spring bean lifecycles : population, initialization, and destroy, the sub-class must implement the interface ImportSelector or ImportBeanDefinitionRegistrar, and can't override those methods:

    Example Usage

    
 public class MyImportRegistrar extends BeanCapableImportCandidate implements ImportBeanDefinitionRegistrar {

     private final Logger logger = getLogger(this.getClass());

     public void registerBeanDefinitions(AnnotationMetadata importingClassMetadata, BeanDefinitionRegistry registry) {
         logger.info("Registering beans from custom registrar");
         registry.registerBeanDefinition("myBean", new RootBeanDefinition(MyBean.class));
     }
 }
