**------------------------ 直 接 上 代 码 -------------------------------------**

需要 jar 包：**logback-core-1.2.3.jar**

> ps：以下代码可根据实际情况在不同的环境的yml文件中配置不同的 logback-\*\*\*.xml ，实现不同环境不同日志输出！

**yml 文件配置：**

logging:
      #日志xml文件
      config: classpath:logback-prod.xml
      level:
        #package下的日志等级
        com.vae: INFO
        #此处关闭  启动应用是打印大量的 CONDITIONS EVALUATION REPORT
        org.springframework.boot.autoconfigure: ERROR

**resources 下新建 logback-prod.xml  文件配置**
