第八篇 SpringBoot 2 x日志配置

在应用中如何使用日志一直以来都是一个问题，前些年流行用AOP的方式在主要方式上切进去，最近几天又看到一篇博文证明了使用这个方式是很不科学的，所以自己记录一篇关于日志的理解吧。 首先关于选用哪种日志也是纠结了半天，log4j,log4j2,slf4j，最终还是选择了LogBack来记录日志，为什么呢，因为这个是SpringBoot自带的呀...

在SpringBoot中LogBack是作为默认的日志依赖关于他的配置的只需要在src/main/resource下面新建一个logback-spring.xml就可以了。为什么是logback-spring.xml而不是logback.xml呢，因为这个文件可以针对不同的profile使用不同的日志配置 ###logback-spring.xml

复制粘贴就好了，如果不需要某个level在文件里删掉就OK

DemoController.java

package com.priv.gabriel.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


/**

@RestController
@RequestMapping("/demo")
public class DemoController {

	private static final Logger logger = LoggerFactory.getLogger(DemoController.class);

	@RequestMapping("/test")
	public void test(){
		logger.info("进入test方法");
		logger.debug("进入test方法");
		logger.warn("进入test方法");
		logger.error("进入test方法");
	}
}

好啦，logback的整合就结束了。 项目下载地址
