Question

我在JBoss AS上使用Seam。在我的应用程序中，我有一个SLSB，它也使用@Name注释声明为接缝组件。我正在尝试使用@In注释在另一个接缝组件中注入和使用此SLSB。

我的问题是，有时Seam注入本地接口（然后代码运行正常），有时seam会注入远程接口（然后执行代码时出错）。我已尝试执行此链接中指定的所有内容：http://docs.jboss.org/seam/2.2.0.GA/reference/en-US/html/configuration.html#config.integration.ejb.container

配置SeamInterceptor，
我在components.xml文件中指定了jndi模式（＆lt; core：init debug =“true”jndi-pattern =“earName /＃{ejbName} / local”/＆gt;），
我也尝试过为每个SLSB使用@JndiName（“earName / ejbName / local”）注释，
我尝试在seam.properties文件中设置此属性（org.jboss.seam.core.init.jndiPattern = earName /＃{ejbName} / local）。
我也尝试将下面的文本放在web.xml文件中

<context-param>
    <param-name>org.jboss.seam.core.init.jndiPattern</param-name>
    <param-value>earName/#{ejbName}/local</param-value>
</context-param>

即使在完成上述所有操作之后，接缝仍然会有时注入远程接口。我在这里错过了什么吗？任何人都可以告诉我如何解决这个问题，告诉缝始终注入本地接口？

我的components.xml文件如下所示：

我的EJB组件看起来像：


@Stateless
@Name("myEJBComponent")
@AutoCreate
public class MyEJBComponentImpl implements MyEJBComponentRemote, MyEJBComponentLocal {

    public void doSomething() {

    }

}

Answer 1

我想以下一个

 public interface MyStateless {

     void doSomething();         

 }

 /**
   * Be aware you CAN NOT USE @Local and @Remote at the same time
   */

 @Local
 public interface MyStatelessLocal extends MyStateless {}

 @Remote
 public interface MyStatelessRemote extends MyStateless {}

你的无国籍应该是

 /**
   * Global JNDI address will be earName/MyStatelessImpl/local and earName/MyStatelessImpl/remote
   */
 @Stateless
 @Name("myStateless")
 public class MyStatelessImpl implements MyStatelessLocal, MyStatelessRemote {

     public void doSomething() {

     }

 }

在Seam组件内

 @Name("otherSeamComponent")
 public class OtherSeamComponent {

     /**
       * Seam will lookup a Seam Component by field name - myStateless
       *
       * Notice i am using the local interface
       */
     private @In MyStatelessLocal myStateless;

 }

Answer 2

@Arthur Ronald F D Garcia：我的不好，我忽略了你上面发布的答案的一小部分。

在我的应用程序中，我有MyStatelessLocal和MyStatelessRemote接口，但没有MyStateless父接口。我在本地和远程接口都添加了抽象方法，并且它们不是空的。

当我创建MyStateless父接口时，将抽象方法从本地和远程接口移动到父接口（以便本地和远程接口为空），错误得到解决，现在我的应用程序正常工作！

非常感谢你的帮助！

如何告诉Seam注入本地EJB接口（SLSB）而不是远程EJB接口（SLSB）？
