spring - 停止tomcat时使用spring服务获取java.io.NotSerializableException

Question

我在 JSF 2 中使用 spring 3
我用 spring bean 替换了 JSF 管理的 bean，方法是在 bean 之上添加:

@Component("mybean")
@Scope("session")

在我的 bean 中，我正在 Autowiring 一个 spring 服务(用 @service 注释声明)

好吧，该服务一切正常，但是当我尝试停止 tomcat 6 时，我的 spring 服务出现此异常

java.io.NotSerializableException

为什么我会收到此异常以及如何解决它的任何想法。

更新:

在使我的服务实现可序列化后，有时我会遇到以下异常:

请指教。

Answer 1

查看错误，看起来 tomcat 正在尝试序列化整个 spring 上下文，我认为这可能是由于您在 Service 上实现了 Serializable 。我在想你可能需要这样做，我不太了解 JSF，但我对作用域 bean 的理解让我想，你可能需要这样的东西

    @Component
    @Scope(proxyMode=ScopedProxyMode.TARGET_CLASS, value="session")
    public class MyBean implements Serializable
    {
       //no need to implement serializable on service
       @Autowired(required=true)
       private MyService service;
    }
