配置简要说明
- 支持应用 '$' 环境变量, 可在spring 容器初始化时 init方式注入
<file>${LOG_PATH}/fill-in-submit.log</file>
- 动态创建 日志文件名，MDC 方式传入变量,logFileName 变量， 需要设置 defalutValue

- 设置打印日志级别,才能输出日志
<logger name="loggerApi" level="INFO" additivity="false">
<!-- additivity false 子 appender 打印了日志，父日志不打印 -->
<appender-ref ref="FILE-API" />
</logger>
- 日志文件大小限制，日志保存天数
<maxFileSize>30MB</maxFileSize>
<!-- 保存日志天数-->
<maxHistory>30</maxHistory>
<totalSizeCap>10GB</totalSizeCap>
每个文件最大30M ，日志文件保存30天，所有日志文件总和 10GB, 例如 日志按日期存放，触发了 日志总和 10GB ，会自动删除 旧的日期 里的日志，始终保持日志总和 10GB
