Question

致力于Spring Boot和Spring Scheduler项目以运行多个批处理。

这是我要写入一个日志文件的所有批次信息。（One log file got created）

现在我需要在不同批次i.e no. of batches = that many no. of log files的单独日志文件中写入信息。

请注意，由于我使用的是Spring Boot，所以我只有一个主类，并且所有批次都只包含一个包，所有批次都只有一个服务，所有批次都只有一个存储库。

您可以将批次名称放在触发您的工作的MDC中，并在logback.xml中使用该密钥

@Scheduled
public void scheduleJob(){
    MDC.put("jobname", jobName);
    // other stuff
}

和logback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

<appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender">
    <!-- in the absence of the class attribute, it is assumed that the
         desired discriminator type is
         ch.qos.logback.classic.sift.MDCBasedDiscriminator -->
    <discriminator>
        <key>jobName</key>
        <defaultValue>batch-service</defaultValue>
    </discriminator>
    <sift>
        <appender name="FILE-${jobName}" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <file>${server.docroot}/logs/${jobName}.log</file>
            <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
              <fileNamePattern>${server.docroot}/logs/${jobName}.%i.log</fileNamePattern>
              <minIndex>1</minIndex>
              <maxIndex>5</maxIndex>
            </rollingPolicy>

            <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
              <maxFileSize>100MB</maxFileSize>
            </triggeringPolicy>
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>%d [%thread] %level %mdc %logger{35} - %msg%n</pattern>
            </layout>
        </appender>
    </sift>
</appender>


<root level="INFO">
<appender-ref ref="SIFT" />
</root>
</configuration>

现在为每个作业创建一个新的日志文件。

如何为单个项目中运行的每个批次创建单独的日志文件？
