父类



public class Bridge<T extends Serializable> {



    private T entity;



    protected void setEntity(final T entity) {

        this.entity = entity;

    }



    public T getEntity() {

        return this.entity;

    }

}

子类



public class StringBridge extends Bridge<String> {



    @Override

    @Autowired

    protected void setEntity(final String entity) {

        // TODO Auto-generated method stub

        super.setEntity(entity);

    }



}

测试



        StringBridge bridge = new StringBridge();

        Method[] methodArr = bridge.getClass().getDeclaredMethods();

        for (Method method : methodArr) {

            System.out.println(method);

            Annotation[] annotations = method.getAnnotations();

            for (Annotation annotation : annotations) {

                System.out.println(annotation);

            }

        }

绝大部分是输出这样的，这个是正常的



protected void com.ces.config.StringBridge.setEntity(java.lang.String)

@org.springframework.beans.factory.annotation.Autowired(required=true)

protected void com.ces.config.StringBridge.setEntity(java.io.Serializable)

偶尔会输出这个，bridge方法上也有注解，有哪位大侠知道的，解释一下，谢谢



protected void com.ces.config.StringBridge.setEntity(java.lang.String)

@org.springframework.beans.factory.annotation.Autowired(required=true)

protected void com.ces.config.StringBridge.setEntity(java.io.Serializable)

@org.springframework.beans.factory.annotation.Autowired(required=true)
