Spring Boot日志处理

2.4 日志处理

2.4.1 记录日志内容

• 请求url
• 访问者ip
• 调用方法classMethod
• 参数args
• 返回内容

2.4.2 新建包aspect，新建日志切面处理类

package com.fei.aspect;

import java.util.Arrays;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.After;
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 // 进行切面操作
@Component // 组件扫描
public class LogAspect {

	private final Logger logger = LoggerFactory.getLogger(this.getClass());

	// 切面
	@Pointcut("execution(* com.fei.controller.*.*(..))")
	public void log() {
	}

	// 切面前操作
	@Before("log()") // 传递切面方法
	public void doBefore(JoinPoint joinPoint) {
		logger.info("---------doBefore------");

		ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
		HttpServletRequest request = attributes.getRequest();

		String url = request.getRequestURL().toString();
		String ip = request.getRemoteAddr();

		Signature signature = joinPoint.getSignature();
		String classMethod = signature.getDeclaringTypeName() + "." + signature.getName();
		Object[] args = joinPoint.getArgs();

		RequestLog requestLog = new RequestLog(url, ip, classMethod, args);

		logger.info("Reqeust : {}", requestLog);
	}

	// 切面后操作
	@After("log()") // 传递切面方法
	public void doAfter() {
		logger.info("---------doAfter------");
	}

	// 切面返回后操作
	@AfterReturning(returning = "result", pointcut = "log()") // 传递切面方法
	public void doAfterReturn(Object result) {
		logger.info("Result : {}", result);
	}

	/**
	 * 封装日志记录需要的内容
	 * 
	 * @author fei
	 *
	 */
	private class RequestLog {
		private String url;// 请求url
		private String ip;// 访问者ip

		private String classMethod;// 调用方法
		private Object[] args;// 参数

		public RequestLog(String url, String ip, String classMethod, Object[] args) {
			super();
			this.url = url;
			this.ip = ip;
			this.classMethod = classMethod;
			this.args = args;
		}

		@Override
		public String toString() {
			return "[url=" + url + ", ip=" + ip + ", classMethod=" + classMethod + ", args=" + Arrays.toString(args)
					+ "]";
		}

	}// RequestLog
}// LogAspect

测试日志切面处理Controller

@Controller
public class IndexController {

	@GetMapping("/{id}/{name}")
	public String toIndex(@PathVariable("id") Integer id, @PathVariable("name") String name) {
		System.out.println("====index()方法执行====");

		return "index";
	}
}
