Java 加载器-弹簧

在我的webapp中，我正在使用GWT，我想使用GwtUploader。问题是我不能@Autowire任何服务到我处理请求的类中。可能是因为它不是弹簧组件，但我不知道如何解决这个问题

这是我的配置：

Servlet：

@Component("gwtUploadServlet")
public class GwtUploadServlet extends UploadAction {

private static final long serialVersionUID = 1L;

    @Autowired
    SomeService .....;

    public String executeAction(HttpServletRequest request,
        List<FileItem> sessionFiles) {

        .....
    }
}

@组件（“gwtUploadServlet”）
公共类GwtUploadServlet扩展了UploadAction{
私有静态最终长serialVersionUID=1L；
@自动连线
一些服务。。。。。；
公共字符串执行（HttpServletRequest，
列表（会话文件）{
.....
}
}

web.xml：

<servlet>
    <servlet-name>gwtUploadServlet</servlet-name>
    <servlet-class>xxx.gwtUploader.GwtUploadServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>gwtUploadServlet</servlet-name>
    <url-pattern>/bbsapp/fileUpload</url-pattern>
</servlet-mapping>

gwtUploadServlet
xxx.gwtUploader.GwtUploadServlet
gwtUploadServlet
/bbsapp/fileUpload

---

我在很多地方使用这些服务，它们工作得很好

我解决了添加以下内容时出现的问题：

@Override
public void init(ServletConfig config) throws ServletException {
    super.init(config);

    // a workaround for forcing this servlet to autowire its components
    WebApplicationContext webAppCtx = WebApplicationContextUtils
            .getRequiredWebApplicationContext(getServletContext());
    webAppCtx.getAutowireCapableBeanFactory().autowireBean(this);
}

现在，我对会话有问题。当我尝试使用服务时，我得到：

Error creating bean with name 'scopedTarget.userSessionService': Scope 'session' 
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: 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.
