这是我面临的挑战:

我有一个servlet程序.我需要将每个用户的日志写入以该用户命名的文件夹.像这样的东西:

    // stores message to David folder
    // /root_path/David/logfile.log
    logger.error(MarkerManager.getMarker("David"), "Error happened");

    // stores message to Mark folder
    // /root_path/Mark/logfile.log                 
    logger.error(MarkerManager.getMarker("Mark"), "Something is broken");

在我的例子中,我使用了标记.但我真的不知道标记是否适合这项任务.

通常,我的appender应该像RollingRandomAccessFile appender一样.我想apppen for appender看起来像这样:

     <RollingRandomAccessFile name="rollingFile"
                 fileName="logs/{markerName ?????}/movie-db.log"
                 filePattern="logs/log-%d{yyyy-MM-dd}-%i.log.zip"
                 append="false"
                 immediateFlush="false"
                 ignoreExceptions="true">
        <PatternLayout pattern="%d{ISO8601} %level{length=5} [%thread] %logger - %msg%n"/>
        <Policies>
            <SizeBasedTriggeringPolicy size="25 MB"/>
            <TimeBasedTriggeringPolicy />
        </Policies>
        <DefaultRolloverStrategy max="10"/>
    </RollingRandomAccessFile>

有任何想法吗？

我有问题,我想将我的Spring WebMVC应用程序的一些进程外包到单独的Threads中.这很容易并且有效,直到我想使用一个使用全局请求的类userRightService.这在线程中不可用,我们遇到了一个问题,这几乎是可以理解的.

这是我的错误:

java.lang.RuntimeException:
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name 'scopedTarget.userRightsService': Scope 'request' is not active
for the current thread; consider defining a scoped proxy for this bean if
you intend to refer to it from a singleton; nested exception is 
java.lang.IllegalStateException: Cannot ask for request attribute - 
request is not active anymore!

好的,够清楚了.我试图通过实现此解决方案来保持请求上下文:

如何在异步任务执行程序中启用请求范围

这是我的runnable类:

@Scope(value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class myThread implements Runnable {

  private RequestAttributes context;

  public DataExportThread(RequestAttributes context) {
    this.context = context;
  }

  public …
