**一、以上是logback-spring.xml,spring boot默认会加载classpath:logback-spring.xml或者classpath:logback-spring.groovy **

**        使用自定义配置文件，配置方式为：**

**         logging.config=classpath:logback-nyist.xml(在application.properties中配置)**

**         注意：不要使用logback这个来命名，否则spring boot将不能完全实例化**

**二、代码中的项目名称和logs日志文件路径需要改变**

**三、项目目录结构如下：**

**![70][]**

**四、以下是log4j2日志配置方法，在classpath添加log4j2.xml或者log4j2-spring.xml（spring boot 默认加载）**

**logj2-spring.xml如下：**

**性能比较：Log4J2 和 Logback 都优于 log4j（不推荐使用）**

**      配置方式：Logback最简洁，spring boot默认，推荐使用**

**文件目录结构如下：**
