SpringBoot2.0日志logback配置

springboot的pom文件都会引一个parent

<parent>
   <groupId>org.springframework.bootgroupId>
   <artifactId>spring-boot-starter-parentartifactId>
   <version>2.0.0.RELEASEversion>
parent>

点进去这个parent，会有一个这个dependency

<parent>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-dependenciesartifactId>
    <version>2.0.0.RELEASEversion>
    <relativePath>../../spring-boot-dependenciesrelativePath>
parent>

再点进去就是2.0版本，所谓的它给你集成的各种包依赖，而且规定了版本号，其中有一个包如下

 <dependency>
    <groupId>org.springframework.bootgroupId>
     <artifactId>spring-boot-starterartifactId>
     <version>2.0.0.RELEASEversion>
 dependency>

再点进去

   <dependency>
     <groupId>org.springframework.bootgroupId>
     <artifactId>spring-boot-starter-loggingartifactId>
     <version>2.0.0.RELEASEversion>
     <scope>compilescope>
   dependency>

再点，啊哈，出来了，这些都是原有的日志包，所以，不必再引依赖了，直接用就ok了，用法如下：

  <dependencies>
    <dependency>
      <groupId>ch.qos.logbackgroupId>
      <artifactId>logback-classicartifactId>
      <version>1.2.3version>
      <scope>compilescope>
    dependency>
    <dependency>
      <groupId>org.apache.logging.log4jgroupId>
      <artifactId>log4j-to-slf4jartifactId>
      <version>2.10.0version>
      <scope>compilescope>
    dependency>
    <dependency>
      <groupId>org.slf4jgroupId>
      <artifactId>jul-to-slf4jartifactId>
      <version>1.7.25version>
      <scope>compilescope>
    dependency>

首先，官方推荐使用的xml名字的格式为：logback-spring.xml而不是logback.xml，至于为什么，因为带spring后缀的可以使用这个标签。
在resource下创建logback-spring.xml文件
内容如下，每行都有注释了

configuration>

然后在yml或者properties中配置

logging.config=classpath:log/logback-spring.xml
logging.path=D:/nmyslog/nmys
