spring拦截器莫名其妙的拦截

Question

使用Spring MVC
写了个拦截器用来拦截Controller中的方法：
@Override
public void before(Method method, Object[] args, Object target)
throws Throwable {
System.out.println("---------------");
System.out.println("method.getDeclaringClass().getName() = " + method.getDeclaringClass().getName());
System.out.println("method.getName()=" + method.getName());
System.out.println("----------------");

}

配置文件：



*Controller



btnInterceptor

但是运行观察控制台发现输出结果为：
[http-8080-1] DEBUG org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'app' processing

request for [/weboa/safe/buildFuncTree.do]

method.getDeclaringClass().getName() = java.lang.Object

method.getName()=toString

[http-8080-1] DEBUG org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping - Mapping

[/safe/buildFuncTree.do] to handler 'cn.edu.swu.oa.safe.controller.SafeController@571688'
[http-8080-1] DEBUG org.springframework.web.bind.annotation.support.HandlerMethodInvoker - Invoking request handler

method: public void cn.edu.swu.oa.safe.controller.SafeController.buildFuncTree

(javax.servlet.http.HttpServletRequest,javax.servlet.http.HttpServletResponse)

method.getDeclaringClass().getName() = cn.edu.swu.oa.safe.controller.SafeController

method.getName()=buildFuncTree

我不清楚

method.getDeclaringClass().getName() = java.lang.Object

method.getName()=toString

这部分是从哪来的，而且tomcat启动时也打印很多次这部分信息

Answer 1

那就得你自己写代码实现
在
public void before(Method method, Object[] args, Object target)
throws Throwable {
这里你可以判断method.getName()为Object的那些方法时直接return
System.out.println("---------------");
System.out.println("method.getDeclaringClass().getName() = " + method.getDeclaringClass().getName());
System.out.println("method.getName()=" + method.getName());
System.out.println("----------------");

}
