springboot项目使用切面记录用户操作日志

浅浅的花香味﹌ 2022-05-13 04:54 454阅读 0赞

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(){
        }
    
        /**

            User user = (User) session.getAttribute("user");
    
            String ip = IpUtils.getIpAddr(request);
    
            try {

            }catch (Exception e){

                logger.error("==前置通知异常==");
                logger.error("异常信息：{}",e.getMessage());
            }
        }

6、开始使用

1）@SystemControllerLog(description = "")

注解加在控制器中方法上面，括号里写上操作描述

![70][]

2）用于监控service异常，可以不使用

@SystemServiceLog(description = "")

注解加在service层方法上面，括号里写上操作描述

（此处为AOP拦截Service记录异常信息。方法不需要加try-catch）

![70 1][]
