Class GenericBeanPostProcessorAdapter<T>

  • Type Parameters:
    T - the type of beans this post-processor will operate on
    All Implemented Interfaces:
    org.springframework.beans.factory.config.BeanPostProcessor
    Direct Known Subclasses:
    InterceptingApplicationEventMulticasterProxy
    public abstract class GenericBeanPostProcessorAdapter<T>
extends java.lang.Object
implements org.springframework.beans.factory.config.BeanPostProcessor
    Generic adapter implementation of the BeanPostProcessor interface, providing type-safe processing for beans of a specific type. This class simplifies the development of typed BeanPostProcessor implementations by allowing subclasses to handle only the bean types they are interested in.

    Subclasses can override either the pre / post initialization hook methods (processBeforeInitialization(Object, String) and processAfterInitialization(Object, String)) if they wish to perform processing without returning a modified bean instance, or the more advanced doPostProcessBeforeInitialization(Object, String) and doPostProcessAfterInitialization(Object, String) methods if they need to return a modified bean instance.

    Example Usage

    
 public class MyBeanPostProcessor extends GenericBeanPostProcessorAdapter<MyBean> {
     protected void processBeforeInitialization(MyBean bean, String beanName) {
         // Custom logic before bean initialization
     }

     protected void processAfterInitialization(MyBean bean, String beanName) {
         // Custom logic after bean initialization
     }
 }
