时间过的真快，转眼就一年了，没想到随手写的笔记会被这么多人浏览，不想误人子弟，于是整理了一个优化版，在这里感谢智斌哥提供的建议和帮助，话不多说，进入正题
所需jar包 ：spring4.3相关联以及aspectjweaver-1.8.5.jar，jdk 1.7，1.8亲测可用，源码下载链接放在最后，关键代码如下：
1.Action
package com.opr.controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import com.opr.service.UserService;@Controller@RequestMapping("user")public class UserController {@Autowired UserService userService;/**** 首页* @param request* @param response* @return ModelAndView*/@RequestMapping("index")public ModelAndView index(HttpServletRequest request,HttpServletResponse response) {return new ModelAndView("index");}/**** 登录* @param request* @param response* @return ModelAndView*/@RequestMapping("userLogin")public ModelAndView userLogin(HttpServletRequest request,HttpServletResponse response,String userName,String password) {ModelAndView mv = new ModelAndView();try {boolean result = userService.userLogin(userName,password);if(result) {mv.setViewName("success");}else {mv.setViewName("error");}} catch (Exception e) {// TODO: handle exception e.printStackTrace();}return mv;}}
2.Service
package com.opr.service.impl;import org.springframework.stereotype.Service;import com.opr.annotation.OperLog;import com.opr.service.UserService;@Service("userService")public class UserServiceImpl implements UserService {//设置默认值，模拟登录private final String userName = "admin";private final String password = "123456";@Override@OperLog(operType="用户登录",userIndex = 0 )//0为下标，代表传入的第一个参数，这里取userName为示例。实际场景可以在session中取操作人！public boolean userLogin(String userName,String password) {boolean flag = false;if(this.userName.equals(userName) && this.password.equals(password)) {flag = true;}return flag;}}
3.自定义注解
package com.opr.annotation;import java.lang.annotation.Documented;import java.lang.annotation.ElementType;import java.lang.annotation.Inherited;import java.lang.annotation.Retention;import java.lang.annotation.RetentionPolicy;import java.lang.annotation.Target;//这里不明白的童鞋可以抽空看看自定义注解@Target({ElementType.METHOD})@Retention(RetentionPolicy.RUNTIME)@Documented@Inheritedpublic @interface OperLog {//操作类型String operType() default "";//操作人String user() default "";//操作人下标int userIndex() default -1;}
4.拦截器
package com.opr.interceptor;import org.aspectj.lang.ProceedingJoinPoint;import org.aspectj.lang.annotation.Around;import org.aspectj.lang.annotation.Aspect;import org.ponent;import com.opr.annotation.OperLog;@Aspect@Componentpublic class OperLogInterceptor {//这里写的为环绕触发 ，可自行根据业务场景选择@Before @After//触发条件为：com.opr包下面所有类且注解为OperLog的@Around("within(com.opr..*) && @annotation(operLog)")public Object doAroundMethod(ProceedingJoinPoint pjd,OperLog operLog) throws Throwable {long startTime=System.currentTimeMillis();//开始时间 Object[] params = pjd.getArgs();//获取请求参数System.out.println("监听到传入参数为:");for(Object param:params) {System.out.println(param);}//###################上面代码为方法执行前#####################Object result = pjd.proceed();//执行方法，获取返回参数//###################下面代码为方法执行后#####################System.out.println("返回参数为:" + result);String user = operLog.userIndex()==-1?operLog.user():(String)params[operLog.userIndex()];//操作人String operType = operLog.operType();//操作类型System.out.println("操作人: " + user +" 操作类型: " + operType);long endTime=System.currentTimeMillis();//结束时间float excTime=(float)(endTime-startTime)/1000;System.out.println("执行时间:"+excTime+"s");System.out.println("#######################分隔符##########################");return result;} }
