Spring Boot 集成 logback日志

• application.properties 配置logback.xml 路径
  注：如果logback.xml在默认的 src/main/resources 目录下则不需要配置application.properties路径
   logging.config=classpath:log/logback.xml
• 配置logback.xml
  注：logback.xml放在src/main/resources目录下新建log文件夹里；

• 在log目录下配置logback.properties

  logback.path=/var/log/project_name
  logback.zip.path=/var/log/zip/project_name
  logback.maxFileSize=xMB
  logback.maxHistory=15
  logback.totalSizeCap=xxxMB
  logback.level=DEBUG
