停止tomcat时,使用spring服务获取java.io.NotSerializableException

Question

我正在使用带有JSF 2的spring 3,并且我用spring bean替换了JSF托管bean,通过在bean的顶部添加:

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

在我的bean中,我正在自动装配一个spring服务(使用注释@service声明)

好吧,一切都运行良好的服务,但当我试图停止tomcat 6,我得到这个例外与我的春季服务

java.io.NotSerializableException

任何想法为什么我得到这个例外,以及如何解决它.

更新:

在使我的服务实现可序列化后,有时我得到以下异常:

请指教.

Answer 1

看看错误,看起来tomcat正在尝试序列化整个spring上下文,我想这可能是因为你正在实现Serializable on Service.我想可能你需要这样做,我不太了解JSF,但我对scoped bean的理解让我想到,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;
    }

Answer 2

好吧，最后我能够让它正常工作，如下所示：

1- 服务：

@Service
@Scope("singleton")
public class PersonService{

}

2- Spring 托管 Bean：

 @Component("person")
   @Scope("session")
   public class PersonBean implements Serializable{

   @Inject
   private PersonService personService;

   }

等待你的反馈。
