程序包 org.springframework.batch.core.listener

类 AbstractListenerFactoryBean<T>

  • 所有已实现的接口:
    org.springframework.beans.factory.FactoryBean<java.lang.Object>, org.springframework.beans.factory.InitializingBean
    直接已知子类:
    JobListenerFactoryBean, StepListenerFactoryBean
    public abstract class AbstractListenerFactoryBean<T>
extends java.lang.Object
implements org.springframework.beans.factory.FactoryBean<java.lang.Object>, org.springframework.beans.factory.InitializingBean
    FactoryBean implementation that builds a listener based on the various lifecycle methods or annotations that are provided. There are three possible ways of having a method called as part of a listener lifecycle:
    • Interface implementation: By implementing any of the subclasses of a listener interface, methods on said interface will be called
    • Annotations: Annotating a method will result in registration.
    • String name of the method to be called, which is tied to a ListenerMetaData value in the metaDataMap.
    It should be noted that methods obtained by name or annotation that don't match the listener method signatures to which they belong will cause errors. However, it is acceptable to have no parameters at all. If the same method is marked in more than one way. (i.e. the method name is given and it is annotated) the method will only be called once. However, if the same class has multiple methods tied to a particular listener, each method will be called. Also note that the same annotations cannot be applied to two separate methods in a single class.
