java - 如何告诉 Seam 注入(inject)本地 EJB 接口(interface)(SLSB)而不是远程 EJB 接口(interface)(SLSB)？

Question

我将 Seam 与 JBoss AS 一起使用。 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(inject)和使用此 SLSB。

我的问题是，有时 Seam 注入(inject)本地接口(interface)(然后代码运行正常)，有时 seam 注入(inject)远程接口(interface)(然后代码执行出错)。我已尝试执行此链接上指定的所有操作:http://docs.jboss.org/seam/2.2.0.GA/reference/en-US/html/configuration.html#config.integration.ejb.container

SeamInterceptor配置好了，
我在 components.xml 文件中指定了 jndi 模式( < core:init debug="true"jndi-pattern="earName/#{ejbName}/local"/> )，
我还尝试为每个 SLSB 使用 @JndiName("earName/ejbName/local") 注释，
我尝试在 seam.properties 文件中设置这个属性( org.jboss.seam.core.init.jndiPattern=earName/#{ejbName}/local )。
我也试过将下面的文本放在 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>  

即使做了上面提到的所有事情，接缝有时仍然会注入(inject)远程接口(interface)。我在这里错过了什么吗？谁能告诉我如何解决这个问题并告诉 seam 始终注入(inject)本地接口(interface)？

我的 components.xml 文件如下所示:

我的 EJB 组件如下所示:

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

    public void doSomething() {

    }

}

Answer 1

我猜是下面的

 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 Stateless 应该是这样的

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

     public void doSomething() {

     }

 }

在你的 Seam 组件中

 @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;

 }
