aop监控spring cloud接口超时，并记录到数据库-编程知识

引入pom

yml配置

mybatis-plus:configuration:log-impl: org.apache.ibatis.logging.stdout.StdOutImplmapper-locations: classpath:mapper/*.xml
server:port: 8082
spring:application:name: ordercloud:nacos:discovery:namespace: publicpassword: nacosserver-addr: localhost:8848username: nacosdatasource:driverClassName: com.mysql.cj.jdbc.Driverpassword: 123456type: com.alibaba.druid.pool.DruidDataSourceurl: jdbc:mysql://localhost:3306/dmg1?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&useSSL=trueusername: root

设置实体类

package com.example.order.entity;import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import lombok.Data;import java.util.Date;/*** 记录接口超时*/
@Data
@TableName("timeout_log")
public class TimeOutLog {//主键@TableId(type = IdType.AUTO)private Long id;//请求方法private String requestMethod;//请求参数private String requestParams;//创建时间private Date createTime;//超时时间private Long time;
}

创建dao

package com.example.order.mapper;import com.baomidou.mybatisplus.core.mapper.BaseMapper;
import com.example.order.entity.TimeOutLog;public interface TimeOutLogMapper extends BaseMapper<TimeOutLog> {}

设置监听类

package com.example.order.config;import com.alibaba.fastjson.JSONObject;
import com.example.order.entity.TimeOutLog;
import com.example.order.mapper.TimeOutLogMapper;
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 java.util.Date;/*** 超时接口监听 记录到数据库*/
@Slf4j
@Aspect
@Component
public class TimedOutListen {@Autowiredprivate TimeOutLogMapper timeOutLogMapper;/*** 环绕通知 监听controller里面的接口超时* @param proceedingJoinPoint* @return* @throws Throwable*/@Around("execution(* com.example.order.controller.*.*(..))")public Object around(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {//返回结果Object result = null;//开始时间long startTime = System.currentTimeMillis();try {//执行方法result = proceedingJoinPoint.proceed();return result;} catch (Throwable throwable) {throw throwable;} finally {//结束时间long endTime = System.currentTimeMillis();//如果大于3000毫秒那么就说明超时了if (endTime - startTime > 3000L) {//方法的名字String method=proceedingJoinPoint.getSignature().toShortString();//超时时间 毫秒long time=endTime-startTime;//请求参数String str= JSONObject.toJSONString(proceedingJoinPoint.getArgs());log.info("请求方法:{},超时时间:{},请求参数:{}",method,time,str);//把超时日志 记录到数据库中TimeOutLog bean=new TimeOutLog();bean.setTime(time);bean.setCreateTime(new Date());bean.setRequestMethod(method);bean.setRequestParams(str);timeOutLogMapper.insert(bean);//TODO 这时候 也可以设置发送短信 或者邮件的功能 通知程序员 去解决这个超时的问题}}}}

创建控制层

package com.example.order.controller;import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;@Slf4j
@RestController
public class OrderController {@GetMapping("/aa")public void aa(@RequestParam("name")String name){log.info("进入添加方法:{}",name);try {//阻塞4秒Thread.sleep(1000*4);} catch (InterruptedException e) {throw new RuntimeException(e);}log.info("添加完毕");}
}

启动类

package com.example.order;import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@MapperScan(basePackages = {"com.example.order.mapper"})
@SpringBootApplication
public class OrderApplication {public static void main(String[] args) {SpringApplication.run(OrderApplication.class, args);}}

创建表

CREATE TABLE `timeout_log` (`id` bigint NOT NULL AUTO_INCREMENT COMMENT '主键',`request_method` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci DEFAULT NULL COMMENT '请求方法',`request_params` text CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci COMMENT '请求参数',`create_time` datetime DEFAULT NULL COMMENT '创建时间',`time` bigint DEFAULT NULL COMMENT '超时时间',PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='接口超时日志表';

在浏览器访问aa这个接口

可以看到超时的信息都记录到数据库中了
