    <!--必填标签，用来指定最基础的日志输出级别-->

        <appender-ref ref="FILE_INFO_LOG" />
        <appender-ref ref="FILE_ERROR_LOG" />
    </root>
</configuration>

部分标签说明

• <root> 标签，必填标签，用来指定最基础的日志输出级别

• <appender-ref> 标签，添加append

• <append> 标签，通过使用该标签指定日志的收集策略

  name属性指定appender命名

  class属性指定输出策略，通常有两种，控制台输出和文件输出，文件输出就是将日志进行一个持久化。ConsoleAppender将日志输出到控制台

• <filter> 标签，通过使用该标签指定过滤策略

• <level> 标签指定过滤的类型

• <encoder> 标签，使用该标签下的标签指定日志输出格式

• <rollingPolicy> 标签指定收集策略，比如基于时间进行收集

• <fileNamePattern> 标签指定生成日志保存地址，通过这样配置已经实现了分类分天手机日志的目标了

application.properties中配置

log.path = ./logs/spring-cloud-project-b
