Spring Boot2.0之统一处理web请求日志
试问,你的项目中,如果有几万个方法,你还这么写log.info("name"+name+",age"+age )日志么?low~
所以用AOP呀
1、首先创建个aop的包(aop的依赖jar包要在pom中搞定),把下面类,贴进去:
package com.toov5.aop; import java.util.Enumeration; import javax.servlet.http.HttpServletRequest; import org.aspectj.lang.JoinPoint; import org.aspectj.lang.annotation.AfterReturning; 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; @Aspect @Component public class WebLogAspect { private static final Logger logger = LoggerFactory.getLogger(WebLogAspect.class); @Pointcut("execution(public * com.itmayiedu.controller.*.*(..))") public void webLog() { } @Before("webLog()") public void doBefore(JoinPoint joinPoint) throws Throwable { // 接收到请求,记录请求内容 ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes(); HttpServletRequest request = attributes.getRequest(); // 记录下请求内容 logger.info("URL : " + request.getRequestURL().toString()); logger.info("HTTP_METHOD : " + request.getMethod()); logger.info("IP : " + request.getRemoteAddr()); Enumeration<String> enu = request.getParameterNames(); while (enu.hasMoreElements()) { String name = (String) enu.nextElement(); logger.info("name:{},value:{}", name, request.getParameter(name)); } } @AfterReturning(returning = "ret", pointcut = "webLog()") public void doAfterReturning(Object ret) throws Throwable { // 处理完请求,返回内容 logger.info("RESPONSE : " + ret); } }
2、后端业务逻辑代码:
package com.toov5.ErrorCatch; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import lombok.extern.slf4j.Slf4j; @RestController //以后经常做微服务异常捕获,要经常用到这个注解 @Slf4j public class ErrorCatch { @RequestMapping("/getUser") public String getUser(int i ){ int j = 1/i; log.info("成功哈"); return "返回"+j; } @RequestMapping("/getMember") public String getMember(String name, Integer age){ // log.info("name"+name+",age"+age );//如果几万个方法都要写这个么? 所以用aop去统一处理 return "okokok"; } }
3、启动类我做了一个小修改哈:
扩大了一下扫描范围
现在整个项目的目录结构是这样的:
启动,请求:
可以看到控制台:
小伙伴是不是很简单啊~
后面会介绍:分布式日志收集系统,也是分布式解决方案的一种~有兴趣有的小伙伴可以自己看下
