1、pom中需要的主要的jar包

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency><!-- https://mvnrepository.com/artifact/cn.hutool/hutool-all --><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId><version>5.3.5</version></dependency><!-- 解析 UserAgent 信息 --><!-- https://mvnrepository.com/artifact/eu.bitwalker/UserAgentUtils --><dependency><groupId>eu.bitwalker</groupId><artifactId>UserAgentUtils</artifactId><version>1.21</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency>

2、log处理的文件

package com.example.springbootpropertiesdemo;import cn.hutool.json.JSONUtil;
import eu.bitwalker.useragentutils.UserAgent;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
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 java.util.Map;
import java.util.Objects;@Aspect
@Component
@Slf4j
public class AopLog {private static  final String  START_TIME = "requeust-start";/*切入点*/@Pointcut("execution(public * com.example.springbootpropertiesdemo.controller.*Controller.*(..))")public void log(){}/*** 前置操作* @param point 切入点*/@Before("log()")public void beforeLog(JoinPoint point){ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();HttpServletRequest request = Objects.requireNonNull(attributes).getRequest();log.info("【请求 URL】：{}", request.getRequestURL());log.info("【请求 IP】：{}", request.getRemoteAddr());log.info("【请求类名】：{}，【请求方法名】：{}", point.getSignature().getDeclaringTypeName(), point.getSignature().getName());Map<String, String[]> parameterMap = request.getParameterMap();log.info("【请求参数】：{}，", JSONUtil.toJsonStr(parameterMap));Long start = System.currentTimeMillis();request.setAttribute(START_TIME, start);}/*** 环绕操作* @param point  切入点* @return  原方法返回值* @throws Throwable*/@Around("log()")public Object aroundLog(ProceedingJoinPoint point) throws Throwable{Object result = point.proceed();log.info("返回值", JSONUtil.toJsonStr(result));return result;}/*** 后置操作*/@AfterReturning("log()")public void afterReturing(){ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();HttpServletRequest request = Objects.requireNonNull(attributes).getRequest();Long start = (Long) request.getAttribute(START_TIME);Long end = System.currentTimeMillis();log.info("【请求耗时】：{}毫秒", end - start);String header = request.getHeader("User-Agent");UserAgent userAgent = UserAgent.parseUserAgentString(header);log.info("【浏览器类型】：{}，【操作系统】：{}，【原始User-Agent】：{}", userAgent.getBrowser().toString(), userAgent.getOperatingSystem().toString(), header);}
}

3、controller

package com.example.springbootpropertiesdemo.controller;import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@EnableAspectJAutoProxy(proxyTargetClass = true)
public class TestController {/*** 测试方法* @param who* @return*/@GetMapping("/test")public String test(){return "你好啊";}
}
