使用 MDC 线程变量

使用 MDC 线程变量，可以将时间作为参数传递 logback。但是通过默认的 discriminator 目前暂且只会定义一个自定义变量。

 public void SendUserObject(AwsLog awsLog) {
      if (awsLog.uid <= 0)
           return;

       String content = String.format("%s_%s_%s_%s\n%s", awsLog.code, awsLog.uid, awsLog.logType, awsLog.date, JSON.toJSONString(awsLog));
       MDC.put("AwsLogType", awsLog.logType.toString());
       MDC.put("test", DateUtils.getPatternHH_Without_DaylightSaving());
       itemLoggerService.log(content);
       if (CurrencyCode.JPY.toString().equals(awsLog.code) && awsLog.logType == AwsLogType.Buy) {
           jpyItemLoggerService.log(content);
       }
       MDC.remove("AwsLogType");
//        MDC.remove("curHour");
    }

<discriminator>
	<key>AwsLogTypekey>
	<defaultValue>nonedefaultValue>
discriminator>

用时区设置

1. 时区的设置：

2. 代码配置 GMT-08:00 ：

<configuration scan="true" scanPeriod="10 seconds" debug="false">
	
	<property name="log_dir" value="logs" />
	
	<property name="maxHistory" value="8640" />

	...
	<property name="pay_log_dir" value="paylogs" />
	<appender name="PAY_HISTORY" class="ch.qos.logback.classic.sift.SiftingAppender">
		
		<discriminator>
			<key>AwsLogTypekey>
			<defaultValue>nonedefaultValue>
		discriminator>
		<sift>
			<appender name="FILE-${AwsLogType}" class="ch.qos.logback.core.rolling.RollingFileAppender">
				
				<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
					<fileNamePattern>${pay_log_dir}/%d{yyyy-MM-dd,aux}/%d{HH,GMT-08:00}/%d{yyyyMMdd,aux}_%d{HH,GMT-08:00,aux}_${AwsLogType}.logfileNamePattern>
					<maxHistory>8640maxHistory>
				rollingPolicy>
				<encoder>
					<charset>UTF-8charset>
					<pattern>%msg%npattern>

	<appender name="PAY_HISTORY_JPY" class="ch.qos.logback.classic.sift.SiftingAppender">
