Springboot 使用logback将各级别日志分别输出到不同路径

        SpringBoot默认已经依赖了部分日志框架（如Logback），且其中推荐使用的也是Logback，所以本次项目中我们将通过新增Logback日志的配置，将各级别日志分别输出到不同路径。SpringBoot已经依赖了Logback，所以不需要手动添加依赖。SpringBoot会自动识别和读取resources目录下新建logback-spring.xml，所以不需要在application.yml进行其他的配置了。

配置文件具体如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <!-- 项目名称 -->
    <property name="PROJECT_NAME" value="XXXXX" />

    <!-- 文件输出格式 -->
    <property name="PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n"/>
    <!-- 输出文件路径 -->
    <property name="OPEN_FILE_PATH" value="logs/manager"/>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
