java - 野蝇群 : lookup ejb remote interface

Question

我生成了两个简单的野蝇群项目。第一个是具有远程接口(interface)的 EJB 外观，第二个应该查找它并发送消息。所以第二个应该是作为客户端。

我已经习惯了野蝇群2017.9.4版

我的 EJB 外观查找路径:

        java:global/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:app/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:module/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:jboss/exported/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote
        java:global/ejb-one/PingFacade
        java:app/ejb-one/PingFacade
        java:module/PingFacade

我的客户:

 public static void main(String[] args) {
        BackendConnectionManager manager = new BackendConnectionManager();
        try {
            manager.getPingFacadeRemote().savePingMessage("halloooooo");
        } catch (NamingException ex) {
            Logger.getLogger(BackendConnectionManager.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    public  PingFacadeRemote getPingFacadeRemote() throws NamingException {
        final Hashtable jndiProperties = new Hashtable();
        jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY,  "org.wildfly.naming.client.WildFlyInitialContextFactory");
              jndiProperties.put(Context.PROVIDER_URL,"http-remoting://localhost:8080");
                 //jndiProperties.put(Context.PROVIDER_URL,"http://localhost:8080");
        final Context context = new InitialContext(jndiProperties);

        return (PingFacadeRemote) context
                .lookup("java:global/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote");
    }

向 pom.xml 添加了客户端依赖项

我不知道客户端的全部依赖关系是什么，并且始终如此

javax.naming.CommunicationException: WFNAM00018: Failed to connect to remote host [Root exception is org.jboss.remoting3.ServiceOpenException: Unknown service name]
    at org.wildfly.naming.client.remote.RemoteContext.getRemoteTransport(RemoteContext.java:80)

    at io.project.ejbtwo.rest.BackendConnectionManager.main(BackendConnectionManager.java:43)
Caused by: org.jboss.remoting3.ServiceOpenException: Unknown service name

另外如何解决在客户端查找中传递安全凭证的问题？

Answer 1

在BackendConnectionManager.java中，第57行，您正在尝试查找服务java:global/ejb-one/PingFacade!io.project.core.interfaces.PingFacadeRemote，但它似乎不存在。 PingFacadeRemote 接口(interface)是ejb-core 模块的一部分。是的，您确实在 ejb-one 模块中实现了它，但您将该接口(interface)注册为远程接口(interface) (@Remote(PingFacadeRemote.class)，在 PingFacade.java).

您可以尝试将其替换为 java:global/ejb-core/PingFacade!io.project.core.interfaces.PingFacadeRemote。
