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
  • 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
• <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<pattern>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
