springboot项目如何使用切面记录用户操作日志

WoddenFish 2022-11-02 我要评论

1、引入springboot-aop集成jar

Spring-boot-start-aop

2、application.yml中启用声明

#spring配置
spring:
  #切面启用
  aop:
    proxy-target-class: true
    auto: true

3、自定义一个拦截controller的注解

package cn.annotation;
 
import java.lang.annotation.*;
 
/**
 * Title: SystemControllerLog
 * @date 2018年8月31日
 * @version V1.0
 * Description:  自定义注解，拦截controller
 */
 
@Target({ElementType.PARAMETER, ElementType.METHOD})//作用在参数和方法上
@Retention(RetentionPolicy.RUNTIME)//运行时注解
@Documented//表明这个注解应该被 javadoc工具记录
public @interface SystemControllerLog {
    String description() default "";
}

4、自定义一个拦截service的注解

package cn.annotation;
 
import java.lang.annotation.*;
 
/**
 * Title: SystemControllerLog
 * @date 2018年8月31日
 * @version V1.0
 * Description:  自定义注解，拦截service
 */
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface SystemServiceLog {
    String description() default "";
}

5、定义日志记录切面

package cn.annotation;
 
import cn.pojo.Action;
import cn.pojo.User;
import cn.service.ActionService;
import cn.utils.IpUtils;
import cn.utils.JsonUtils;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterThrowing;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;
 
import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import java.lang.reflect.Method;
import java.util.Date;
 
/**
 * Title: SystemControllerLog
 * @date 2018年8月31日
 * @version V1.0
 * Description: 切点类
 */
@Aspect
@Component
@SuppressWarnings("all")
public class SystemLogAspect {
    //注入Service用于把日志保存数据库，实际项目入库采用队列做异步
    @Resource
    private ActionService actionService;
    //本地异常日志记录对象
    private static final Logger logger = LoggerFactory.getLogger(SystemLogAspect.class);
    //Service层切点
    @Pointcut("@annotation(cn.annotation.SystemServiceLog)")
    public void serviceAspect(){
    }
 
    //Controller层切点
    @Pointcut("@annotation(cn.oa.annotation.SystemControllerLog)")
    public void controllerAspect(){
    }
 
    /**
     * @Description  前置通知  用于拦截Controller层记录用户的操作

     */
 
    @Before("controllerAspect()")
    public void doBefore(JoinPoint joinPoint){
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
        HttpSession session = request.getSession();
        //读取session中的用户
        User user = (User) session.getAttribute("user");
 
        String ip = IpUtils.getIpAddr(request);
