我们正在使用带有 flex 作为客户端的 glassfish/websphere 的 spring mvc。其中一个 Web 服务需要向客户端返回指示,然后继续异步执行而不需要返回任何内容。

我们尝试使用纯 Java 线程,但它不起作用,因为 Spring 无法访问 Web 应用程序上下文。

然后我们尝试以“弹簧方式”(使用 @async + )使用线程,但弹簧抛出异常:

编辑:确实我们需要留在会话/请求范围内,因为异步(线程)部分需要使用在会话范围内定义的应用程序内的bean,例如bean之一(这是异常抱怨的):

@Component("sessionCachedUserMetadata")
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
@Lazy(true)
public class UserMetadataSessionCachedService implements UserMetadataBusinessService {
