Spring general configuration file template (logback, pom and other configuration files)

This article mainly stores general-purpose configuration file templates, and most projects can be used out-of-the-box (or simply modified).

Log configuration file for Spring Boot

Spring Boot uses self4j + logback logging tools by default. Put logback-spring.xml in the resources folder, the content is as follows

<!-- 日志配置文件加载顺序： logback.xml → application.properties(yml) → logback-spring.xml -->
<!-- 官方推荐使用logback-spring.xml，因此它晚于application.properties(yml)加载，可以获得application.properties(yml)定义的变量 -->
<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <!-- 全局属性变量 -->
    <springProperty scope="context" name="ROOT_DIR" source="logback.rootDir" defaultValue="logs"/>
    <springProperty scope="context" name="APP_NAME" source="spring.application.name"/>
    <!-- 保留日志的天数 -->
    <property name="RETAINED_FILE_DAYS" value="90"/>
    <!-- 同类日志占用的总空间大小（多天总和），超过将被删除 -->
    <property name="TOTAL_SIZE_CAP" value="20GB"/>
