SpringAop之日志管理

导入的依赖均为JavaWeb界面在线配置代码生成器这篇文章，你只需将这篇文章的maven依赖导入即可。

SpringAop利用注解的特性进行日志管理，只需在对应的方法上加上自己编写的注解，即可完美实现日志管理。

日志管理的目的是，将后台管理人员，安卓人员，第三方人员每天请求的url和是谁操作的，在哪操作，使用什么系统操作，输入的那些参数，使用什么请求等等统统记录下来。方便异常排查和应对外来的web攻击。

关于Controller和spring-mvc.xml使用了shiro,关于shiro方面可以参考我的如下文章，进行学习:

步骤如下:

一、编写注解类

package com.anotation;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;


@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SysLog {
    
    String type() default "";//日志类型
    String action() default "";//作用
    String method() default "";//请求方式

}

二、编写Aspect

package com.anotation;

import java.io.IOException;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.lang.reflect.Method;
import java.math.BigDecimal;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import com.baomidou.mybatisplus.mapper.EntityWrapper;
import com.entity.SysCompany;
import com.entity.SysUser;
import com.service.SysCompanyService;
import com.service.SysLogService;
import com.service.SysUserService;

import cn.hutool.core.date.DateUtil;
import cn.hutool.system.HostInfo;
import cn.hutool.system.OsInfo;
import cn.hutool.system.SystemUtil;



public class SysLogAspect {

    @Autowired
    private SysLogService sysLogService;
    
    @Autowired
    private SysUserService userService;
    
    @Autowired
    private SysCompanyService companyService;

    /**
     * 环绕通知
     * 
     * @param joinPoint
     * @return
     * @throws Throwable
     */
    public Object aroud(ProceedingJoinPoint joinPoint) throws Throwable {

        // 开始时间
        long beginTime = System.currentTimeMillis();

        // 执行目标方法
        Object result = joinPoint.proceed();

        // 执行时长(毫秒)
        long time = System.currentTimeMillis() - beginTime;

        // 保存日志
        saveSysLog(joinPoint, time);
        
        return result;
    }

    /**
     * 保存日志
     * 
     * @param joinPoint
     * @param time
     */
    private void saveSysLog(ProceedingJoinPoint joinPoint, long time) {
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        Method method = signature.getMethod();
        
        SysLog sysLog = method.getAnnotation(SysLog.class);
        
        com.entity.SysLog log = new  com.entity.SysLog();
        
        HttpServletRequest request = ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes()).getRequest();
        
        //获取session
        String userCode = (String) request.getSession().getAttribute("userCode");
        
        //获取用户信息
        EntityWrapper<SysUser> wrapper = new EntityWrapper<SysUser>();
        wrapper.eq("user_code", userCode);
        SysUser user = userService.selectOne(wrapper);
        
        //获取公司信息
        EntityWrapper<SysCompany> wrapper2 = new EntityWrapper<SysCompany>();
        wrapper2.eq("company_code", user.getCorpCode());
        SysCompany company = companyService.selectOne(wrapper2);
 
            
            if (sysLog != null) {
                
                HostInfo hostInfo = SystemUtil.getHostInfo();
                OsInfo osInfo = SystemUtil.getOsInfo();
                log.setLogType(sysLog.type());
                log.setLogTitle(sysLog.action());
                log.setRequestMethod(sysLog.method());
                log.setRequestUri(request.getRequestURI());
                log.setRemoteAddr(request.getRemoteAddr());
                log.setDeviceName(osInfo.getName());
                log.setBrowserName(request.getHeader("User-Agent"));
                log.setRequestParams(request.getQueryString());
                log.setCreateBy(user.getUserName());
                log.setCreateByName(user.getUserName());
                log.setCreateDate(DateUtil.date().toString());
                log.setServerAddr(hostInfo.getAddress());
                log.setExecuteTime(BigDecimal.valueOf(time));
                log.setIsException("否");
                log.setCorpCode(company.getCorpCode());
                log.setCorpName(company.getCompanyName());
                
            }  
            // 保存系统日志
            sysLogService.insert(log);

    }
    
    
    
   
      

}

三、在spring-mvc.xml配置aop

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

        <mvc:message-converters register-defaults="true">

                  class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>

    </mvc:annotation-driven>
    <!-- 上传限制 -->

        <aop:around method="aroud" pointcut-ref="sysLogPointcut"/>
    </aop:aspect>
</aop:config>
</beans>

四、在对应的Controller方法上加上注解即可

/**
     * 账号登录
     * @param request
     * @return
     */
    @PostMapping(value = "/login",produces="application/json;charset=utf-8")
    @SysLog(type="后台系统",action="登录功能",method="POST")
    @ApiOperation(value="登录",httpMethod="POST",notes="登录")
    public JSONObject login(@RequestParam String username, @RequestParam String password, HttpSession session,HttpServletResponse response) {
        //接收前台参数
        logger.info("用户名:"+username);
        logger.info("密码:"+password);
        //调用查询逻辑
        EntityWrapper<SysUser> wrapper = new EntityWrapper<SysUser>();
        wrapper.eq("login_code", username);
        SysUser user = userService.selectOne(wrapper);
        
        JSONObject json = new JSONObject();
        
        if(user != null && "0".equals(user.getStatus())) {
            //获取当前用户
            Subject subject = SecurityUtils.getSubject();  
            
            //根据前台传的用户名和密码进行认证
            UsernamePasswordToken token = new UsernamePasswordToken(username, password);         
      
            try {
                //认证通过
                subject.login(token); 
            
                String encode = Base64.encode(user.getUserCode());
                
                //Cookie有效期默认为8小时
                int time=28800;
                
                //将Cookie加密为16进制字符串
                CookieUtils.setCookie(response,  "userCode", encode, time);

                user.setLastLoginDate(DateUtil.date());
                userService.updateById(user);
                
                //将userCode放入session中保存
                session.setAttribute("userCode", user.getUserCode());
                
                json.put("token", subject.getSession().getId());
                json.put(CommonEnum.RETURN_CODE, "000000");
                json.put(CommonEnum.RETURN_MSG, "登录成功");
            } catch (IncorrectCredentialsException e) {
                json.put(CommonEnum.RETURN_CODE, "111111");
                json.put(CommonEnum.RETURN_MSG, "用户名或密码错误");
            }catch (Exception e) {
                json.put(CommonEnum.RETURN_CODE, "222222");
                json.put(CommonEnum.RETURN_MSG, "特殊异常");
            }
        }else {
            json.put(CommonEnum.RETURN_CODE, "500");
            json.put(CommonEnum.RETURN_MSG, "用户不存在");
        }    
        
        return json;

    }
