springboot程序logback日志基本配置，多个包不同日志级别输入到文件中

日志是程序中必不可少的内容。依据日志我们可以有效诊断程序bug，统计用户访问和各主要功能的使用频率时间段等信息。因此我们会需要不同package使用不同的日志级别，以及不同业务的日志输出到不同的文件。下面本文简要概述如何使用logback将不同包的不同级别日志输出到info1.txt中。

本文的代码在[这里][Link 1]，欢迎加星，fork。  
**1， springboot配置日志logback日志的方式**  
官方文档在https://docs.spring.io/spring-boot/docs/1.5.12.RELEASE/reference/html/boot-features-logging.html\#boot-features-logging-format

我们一般只需要在application.properties中设置类似如下的配置即可。

logging.config=classpath:logback-spring2.xml

**2，程序的基本结构**  
程序是标准的springboot程序，基于springboot 1.5.12， 使用swagger访问rest。包含service包和controller包。

**3，logback.xml配置**  
简要介绍，logback配置文件中有3个appender， 分别为， a，控制台（级别为debug）输出到console中，b，FILE(没有定义级别)输出到logs/info1.log中，自动归档每天的日志，修改为2018-11-10.txt这样保存起来。只保留最近7天的日志。c，ERROR\_FILE与FILE类似，只记录error级别的日志。

## xml文件解释 ##

com.yq.controller包trace级别及其以上的日志，com.yq.service包info级别及其以上的日志，org.springframework.beans包debug级别及其以上的日志会记录在FILE中，也就是记录到info1.txt中

启动程序后访问http://127.0.0.1:9090/swagger-ui.html\#/user-controller/getUserUsingGET， 点击getUser方法。  
然后查看控制台日志，程序所在目录下的logs目录中的info1.txt和error1.txt。

**结果**，按照如上配置，  
info1.txt记录了很多springboot的日志包括debug级别的日志，  
com.yq.controller包下面的所有trace级别以上信息  
com.yq.service包下面的所有info级别以上的信息  
org.springframework.beans包下面的所有debug级别以上的信息  
error1.txt只记录com.yq.LogbackApplication的错误日志，没有com.yq.controller和com.yq.controller的错误  
console中controller包和servcie包都没有记录， 只有springboot的com.yq.LogbackApplication的日志

**info1.txt内容为**
