【问题描述】：

我想在 Java 项目中使用 XMPP 服务器“Apache Vysper”，所以我复制了这个示例代码：

public class Start 

    /**
     * 
     * @param args
     */
    public static void main(String[] args) throws AccountCreationException,
    EntityFormatException, FileNotFoundException 

        // choose the storage you want to use
        //StorageProviderRegistry providerRegistry = new JcrStorageProviderRegistry();
        StorageProviderRegistry providerRegistry = new MemoryStorageProviderRegistry();

        final AccountManagement accountManagement = (AccountManagement) providerRegistry
                .retrieve(AccountManagement.class);

        Entity user1 = EntityImpl.parse("[e-mail]");
        if (!accountManagement.verifyAccountExists(user1)) 
            accountManagement.addUser(user1, "password1");
        
        Entity user2 = EntityImpl.parse("[e-mail]");
        if (!accountManagement.verifyAccountExists(user2)) 
            accountManagement.addUser(user2, "password1");
        
        Entity user3 = EntityImpl.parse("[e-mail]");
        if (!accountManagement.verifyAccountExists(user3)) 
            accountManagement.addUser(user3, "password1");
        


        XMPPServer server = new XMPPServer("vysper.org");

        server.addEndpoint(new TCPEndpoint());

        WebSocketEndpoint wsEndpoint = new WebSocketEndpoint() 

            // example of how you can combine Vysper with other resources 
            @Override
            protected Server createJettyServer() 
                Server jetty = super.createJettyServer();
                ResourceHandler resourceHandler = new ResourceHandler();
                resourceHandler.setResourceBase("src/examples/client");
                jetty.setHandler(resourceHandler);
                HandlerCollection handlers = new HandlerCollection();
                handlers.addHandler(resourceHandler);
                jetty.setHandler(handlers);

                return jetty;
            
        ;
        wsEndpoint.setContextPath("/ws");
        server.addEndpoint(wsEndpoint);

        server.setStorageProviderRegistry(providerRegistry);

        server.setTLSCertificateInfo(new File("src/cert/bogus_mina_tls.cert"),
        "boguspw");

        try 
            server.start();
            System.out.println("vysper server is running...");
         catch (Exception e) 
            e.printStackTrace();
        

        server.addModule(new SoftwareVersionModule());
        server.addModule(new EntityTimeModule());
        server.addModule(new VcardTempModule());
        server.addModule(new XmppPingModule());
        server.addModule(new PrivateDataModule());
    
 

但是当我运行代码时，我总是得到一个“java.net.BindException”：

log4j:WARN No appenders could be found for logger (org.apache.vysper.xmpp.server.DefaultServerRuntimeContext).
log4j:WARN Please initialize the log4j system properly.

我用的是 linux。

我做错了什么？ 谢谢！

【参考方案1】：

根据您的错误，我认为该端口已被阻止。默认情况下，vysper 使用 5222 端口。检查您的防火墙或其他应用是否阻止了此端口。
