一、基於springaop實現用戶操作的日志記錄

原文：https://www.jianshu.com/p/d0bbdf1974bd

代碼內容為我自己的，並且把依賴的包也錄入進來。

一、引入aop依賴

<!--aop-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

二、創建一個實體類

　

package com.sj56.breakfast.entity;

import lombok.Data;

import java.io.Serializable;
import java.util.Date;

@Data
public class UserLog implements Serializable {

    //id
    private long id;
    //操作用戶用戶名
    private String userName;
    private long userId;
    //用戶操作
    private String operation;
    //方法名
    private String method;
    //ip
    private String ip;
    //操作時間
    private Date createTime;

}

 

三、自定義一個注解

package com.sj56.breakfast.config.annotation;


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)
public @interface UserOperation {

    String value() default "";
}

四、創建AOP切面類

package com.sj56.breakfast.config.aspect;

import com.sj56.breakfast.config.annotation.UserOperation;
import com.sj56.breakfast.entity.UserLog;
import com.sj56.breakfast.service.userlog.UserLogService;
import org.aopalliance.intercept.Joinpoint;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import javax.xml.ws.spi.http.HttpContext;
import java.lang.reflect.Method;
import java.util.Date;
import java.util.HashMap;

@Aspect
@Component
public class UserLogAspect {

    @Autowired
    private UserLogService userLogService;

    @Autowired
    private UserLog userLog;

    //在注解的位置切入代碼
    @Pointcut("@annotation( com.sj56.breakfast.config.annotation.UserOperation )")
    public void loginPointCut(){

    }

    @After("loginPointCut()")
    public void logSave(JoinPoint pjp){
        System.out.println("保存日志切面~~~~");

        //獲取方法
        MethodSignature methodSignature = (MethodSignature) pjp.getSignature();
        Method method = methodSignature.getMethod();
        userLog.setMethod(method.getName());

        //獲取操作
        UserOperation userOperation = method.getAnnotation(UserOperation.class);
        if (userOperation != null){
            String value = userOperation.value();
            userLog.setOperation(value);
        }

        //獲取ip
        ServletRequestAttributes sra = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = sra.getRequest();

        String ip = request.getRemoteAddr();
        userLog.setIp(ip);

        //獲取用戶
        String userId = request.getParameter("userId");
        System.out.println("用戶id："+userId);
        if (userId == null || userId == ""){
            userId = "0";
        }
        //可通過用戶id查詢用戶name
        userLog.setUserId(Long.valueOf(userId));

        //操作時間
        userLog.setCreateTime(new Date());

        //保存日志
        userLogService.saveLog(userLog);


    }
}

 

 

五、攔截實例

//添加一個店鋪
@UserOperation(value = "保存一個店鋪")
@RequestMapping("/save")
public BFResponse shopSave(Shop shop, @RequestParam HashMap map){
    System.out.println("保存店鋪map-->:"+map);
    shopService.shopSave(shop);
    return BFResponseUtils.success();
}

數據困user_name列為了方便隨便設置了一個字段插入
