创建数据库表

-- 操作日志
create table operate_log (id int unsigned primary key auto_increment comment'id',operate_user int unsigned comment '操作人员Id',operate_time datetime comment '操作时间',class_name varchar(100)comment '操作类',method_name varchar(100)comment '操作的方法',method_params varchar(1000)comment '方法参数',return_value varchar(2000)comment '返回值',cost_time bigint comment '方法执行耗时, 单位：ms') comment '操作日志表';

引入APO依赖

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

 

创建数据库对应的类

@Data
@NoArgsConstructor
@AllArgsConstructor
public class OperateLog {private Integer id;private Integer operateUser;// 操作人员的idprivate LocalDateTime operateTime;//操作时间private String className; // 操作类名private String methodName ; //操作方法private String methodParams; //方法参数private String returnValue; //返回值private Long costTime; //操作耗时

创建注解类

package com.it.anno;import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;@Retention(RetentionPolicy.RUNTIME) //运行的时候
@Target(ElementType.METHOD) //目标是方法
public @interface Log {}

创建AOP类

package com.it.aop;import com.alibaba.fastjson.JSONObject;
import com.it.mapper.OperateLogMapper;
import com.it.pojo.OperateLog;
import com.it.utils.JwtUtils;
import io.jsonwebtoken.Claims;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.time.LocalDateTime;
import java.util.Arrays;@Slf4j
@Component
@Aspect //切面类
public class LogAspect {@Autowiredprivate HttpServletRequest response;@Autowiredprivate OperateLogMapper operateLogMapper;@Around("@annotation(com.it.anno.Log)")public Object recordLog(ProceedingJoinPoint joinPoint) throws Throwable{//id 自增//操作人的idString jwt= response.getHeader("token");Claims claims = JwtUtils.parseJWT(jwt);Integer operateUser =(Integer) claims.get("id");//操作时间LocalDateTime operateTime = LocalDateTime.now();//操作类名String className = joinPoint.proceed().getClass().getName();//操作方法名String methodName = joinPoint.getSignature().getName();//操作方法参数Object[] args = joinPoint.getArgs();String methodParams = Arrays.toString(args);//记录时间 （开始）long begin = System.currentTimeMillis();//调用原始的目标方法运行Object proceed = joinPoint.proceed();//记录时间 （结束）long end = System.currentTimeMillis();//方法返回值String returnValue = JSONObject.toJSONString(proceed);//耗时时间long costTime = end - begin;//记录日志OperateLog operateLog=new OperateLog(null,operateUser,operateTime,className,methodName,methodParams,returnValue,costTime);operateLogMapper.insert(operateLog);log.info("AOP记录操作日志:{}",operateLog);return proceed;}
}

 每个方法上把自定义的@Log注解引入进来

 /*根据ID删除部门*///@DeleteMapping("/{id}")@Log@DeleteMapping("/depts/{id}")public Result delete( @PathVariable Integer id) throws Exception {log.info("根据ID删除部门:{}",id);deptservec.delete(id);return Result.success();}//新增部门// @PostMapping@Log@PostMapping ("/depts")public Result add( @PathVariable Dept dept) {log .info("新增部门:{}",dept);deptservec.add(dept);return  Result.success();}
