说明

日志是一个系统很重要的一部分，在生产时间中，逐渐形成了一套自己的日志规范，方便大家集成。

配置文件配置 application.yml

logging:
  config:
    classpath: logback-spring.xml
    path: /var/log/${spring.application.name}
  myFileName: ${spring.application.name}
  # 分割文件设置 超过 100MB就进行分割，最大保留历史 90天
  maxFileSize: 100MB
  maxHistory: 90
  level:
    root: INFO
    org.springframework.web: INFO
    org.springframework.security: INFO
    # 自己工程命名的类
    com.project: DEBUG

logback-spring.xml 配置文件

经过实践 ，对logback进行了优化，此文件需要放入 src/main/resources下，
会生成两个文件
开发调试（{myFileName}-base.log）： 包含debug级别
上生产（{myFileName}-info.log）： 排除debug级别，也就是info级别，可以定义友好中文释义输出。

具体优化如下：
