Spring aop 记录操作日志 Aspect 自定义注解

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
@Inherited
public @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.springframework.stereotype.Component;

import com.opr.annotation.OperLog;

@Aspect
@Component
public 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;
        
    } 
    
    
}
