JAVA 泛型编译（JDK1.7）

[begoodluck]

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)
