java - 有状态 bean 远程 EJB 调用第二次失败

Question

我正在编写带有状态 bean 的 EJB 代码。

HelloStatefulBean 打包在 .EAR 文件中，EjbClient 打包在 .WAR 文件中，这两个存档都部署在 JBOSS-EAP-6.2 服务器中。EjbClient.java 文件通过 REST-API(/test/execute) 调用

我从 EjbClient.java 类调用 EJB。从客户端到 EJB 对第二个方法(sayHi())的调用失败，并出现“NoSuchEJBException”，这种行为看起来有点奇怪，因为在相同的上下文中我能够成功调用第一个方法(sayHello())。

请告诉我，我错过了什么？

这是我的代码:

Stateful bean:
    @Stateful(name = "helloejb")
    @StatefulTimeout(unit = TimeUnit.MINUTES, value = 1)
    @TransactionManagement((TransactionManagementType.BEAN))
    public class HelloStatefulBean extends CloudProvider implements IHelloBean
    {
        public String sayHello(String name)
        {
            String str = "Hello " + name;
            System.out.println(str);
            ....
            ...
            ..
            .
            return str;
        }

        public void sayHi(String str)
        {
            System.out.println("Hi " + str);
            ....
            ...
            ..
            .
        }
    }

Remote Interface:
    @Remote
    public abstract interface IHelloBean
    {
        public abstract String sayHello(String paramString1);

        public abstract void sayHi(String paramString1);
    }

EJB Client:
    @Path("/test")
    public class EjbClient
    {
        @POST
        @Path("/execute")
        public Response execute()
        {
            String lookupName = "java:global/hello/hello/helloejb!com.test.beans.ifc.IHelloBean";
            Context initialContext = new InitialContext();
            LOGGER.info("Looking-up the EJB with name: " + lookupName);
            IHelloBean objRef = (IHelloBean)initialContext.lookup(lookupName);
            LOGGER.info("Lookup successful.");
            String msg = objRef.sayHello("XYZ");

            objRef.sayHi(msg);   // Fails on this method call with NoSuchEJBException
        }

    } 

使用 URL 触发 REST-API 时: http://{JBOSS-SERVER-IP}:8080/api/test/execute ，REST-API 被调用，并且 EJB 的查找也成功。此外，“sayHello()”方法也被成功调用，但是在从 EjbClient 调用“sayHi()”方法时，应用程序失败并出现异常:

Answer 1

如果删除 @StatefulTimeout 解决了 NoSuchEJBException 异常，并且假设您在 bean 保持 Activity 状态的时间段(1 分钟)内调用第一个和第二个方法，则可能是容器对此注释存在一些问题。我在谷歌上做了一些研究，但没有发现任何关于这个问题的可能的错误。

关于您的评论，答案是否定的，在调用第二个方法之前进行新的查找不是解决方案，因为您将获得具有不同状态的不同 ejb 引用。它之所以有效，是因为在您的示例中您没有管理状态，但在实际需求下您将需要保留相同的 ejb 引用。 (这就是stateful的原因)
