使用Spring MVC拦截器实现日志记录的方法

最近在研究Spring MVC拦截器，那么今天也算个学习笔记吧！有需要了解使用Spring MVC拦截器实现日志记录的朋友可参考。希望此文章对各位有所帮助。

1.  定义一个类实现HandlerInterceptor，比如： 

public class MyInterceptors implements HandlerInterceptor{ 
    
  public void afterCompletion(HttpServletRequest arg0, 
      HttpServletResponse arg1, Object arg2, Exception arg3) 
      throws Exception { 
    // TODO Auto-generated method stub 
    System.out.println("MyInterceptors afterCompletion"); 
  } 
   
  public void postHandle(HttpServletRequest arg0, HttpServletResponse arg1, 
      Object arg2, ModelAndView arg3) throws Exception { 
    // TODO Auto-generated method stub 
    System.out.println("MyInterceptors postHandle");     
  } 
 
   
  public boolean preHandle(HttpServletRequest arg0, HttpServletResponse arg1, 
      Object arg2) throws Exception { 
    // TODO Auto-generated method stub 
    HandlerMethod handlerMethod = (HandlerMethod) arg2;  
    System.out.println("MyInterceptors preHandle 调用方法名："+handlerMethod.getMethod().getName()); 
     
 
    return true; 
  } 
 
} 

2.在Springmvc.xml中装配
