springboot，war包部署到Tomcat，logback 日志 不按日滚动。

springboot，war包部署到Tomcat，logback 日志 不按日滚动，只生成了一个单文件。
logback-spring.xml，如下：

 <?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
    <include resource="org/springframework/boot/logging/logback/base.xml"/>
    <contextName>default</contextName>
