multithreading - 在单独的线程中使用$ {resource}？

Question

我要执行一个简单的任务!但不知道是否有可能!

我有一个实现Runnable的常规类，并且已经使用ThreadPool运行了!我想在Runnable类中执行以下操作:

    public void run() {
          EventPhoto.withTransaction { status ->

                EventPhoto photo = new EventPhoto(event:eventInstance)

                photo.imageUrl = "${resource(dir:'images/uploads',file:image.name, absolute:true)}"
                photo.thumbnailUrl = "${resource(dir:'images/uploads',file:thumb.name, absolute:true)}"
          }
    }

事实是，由于我的线程不在webrequest内部运行，因此出现以下错误:

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

所以仍然有使用$ resource()吗？

谢谢
