Question

问题详细信息

我们的应用程序是运行在tomcat容器上的高线程应用程序。该应用程序是基于弹簧的应用程序。这是一个多线程应用程序。但是，一段时间后，该应用似乎没有响应。我们进行了线程转储，发现所有线程都在等待在堆栈跟踪中创建的spring bean。这是下面的线程转储。

代码结构和代码功能概述

我从JMS服务器收到一条消息，我需要找到正确的bean实例来解析消息的内容。

这是我的代码结构

@Configuration         
public class AppConfiguration {


    @Lookup
    public SamTorcher getSamTorcherParser() {
        return null;
    }       
   }

    @Component
    @Scope("prototype")
    public class SamTorcher {
    }

在这里，我得到了SamTorcher类，该类由@Component批注和@Scope("prototype")定义。在这里，我有一个@Configuration注释的AppConfiguration类，旨在引导所有必需的配置。

当我收到消息时，基于messageType，我使用SamTorcher方法查找config.getSamTorcherBean() bean。

以下是spring.io网站上与上述问题相关的JIRA（https://jira.spring.io/browse/SPR-7949），我目前正面临同一问题。但是，我尚未找到解决此问题的正确方法。

对此表示感谢。
