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>
