logback加载配置时，按以下顺序查找 logback.groovy ，logback-test.xml，logback.xml
%-4level %d{HH:mm:ss.SSS} %thread %logger - %msg%n WARN ${catalina.base}/groupmsg_error.log crash_error.%d{yyyy-MM-dd}.log 30 [%-4level][%d{HH:mm:ss.SSS}][%thread][%logger] - %msg%n DEBUG ${catalina.base}/groupmsg_info.log groupmsg_info.%d{yyyy-MM-dd}.log 30 [%-4level][%d{HH:mm:ss.SSS}][%thread][%logger] - %msg%n DEBUG ${catalina.base}/groupmsg_xiao.log groupmsg_xiao.%d{yyyy-MM-dd}.log 30 [%mdc{user}][%-4level][%d{HH:mm:ss.SSS}][%thread][%logger] - %msg%n
