springboot logback配置

1.pattern解析：

　　%d{yyyy-MM-dd‘T‘HH:mm:ss.SSSXXX} 　　带时区的时间

　　%level 　　日志级别

　　[%thread] 　　线程名

　　[%logger{50}:%line]  　　打印日志对应的方法和行数
　　[uuid:%X{operation_id}] 　　这个是logback的MDC机制，没有使用mdc的话不需要用这个字段
　　%msg%n  　　　　　　　　这个是要打印的数据，%n是换行
　　%caller{2, DISP_CALLER_EVAL} 　　这个是指打印调用栈，即当前方法和调用这个方法的父级方法（这里配置2，只会往上打印一层）

<property name="error.pattern" value="%d{yyyy-MM-dd‘T‘HH:mm:ss.SSSXXX} %level [%thread] [%logger{50}:%line] [uuid:%X{operation_id}] %msg%n %caller{2, DISP_CALLER_EVAL}"></property>

2.将不同级别的日志打印到不同的文件：
　　下面的一句话表示这个appender只接受error日志的级别，其它级别的日志丢弃

　　　　　　<filter class="ch.qos.logback.classic.filter.LevelFilter">
             <level>ERROR</level>
             <onMatch>ACCEPT</onMatch>
             <onMismatch>DENY</onMismatch>
         </filter>
3.logger配置
　　每个logger可以配置对应的package，打印级别，additivity="true"表示这个logger匹配的日志，依然会抛到上层，父logger（也就是root），root可以打印到控制台
　　appender-ref 指定appender，每个appender定义具体的工具方式，打印、压缩策略

　　　  　<logger name="com.hikvision.log" level="DEBUG" additivity="false">
              <appender-ref ref="only-error" additivity="false"></appender-ref>
              <appender-ref ref="no-error"></appender-ref>
         </logger>

 12     <property name="error.pattern"
 13         value="%d{yyyy-MM-dd‘T‘HH:mm:ss.SSSXXX} %level [%thread] [%logger{50}:%line] [uuid:%X{operation_id}] %msg%n %caller{2, DISP_CALLER_EVAL}"></property>
