如何使用Smack 4.2连接到ejabberd？

Question

我已经更改了我的应用程序以使用Smack 4.2替换Smack 4.1

但是我在config.setServiceName()中遇到错误;

此方法的参数已从String更改为DomainBareJid.我不知道如何在这个新的Smack中使用DomainBareJid和setServiceName.

XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration
                .builder();
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);


        config.setServiceName("What should i put here?");


        config.setHost(serverAddress);
        config.setPort(5222);
        config.setDebuggerEnabled(true);
        connection = new XMPPTCPConnection(config.build());

        connection.setUseStreamManagement(true);

如果我没有设置服务名称,那么我收到以下错误:

请提供一些示例代码来设置serviceName.

Answer 1

DomainBareJid serviceName = JidCreate.domainBareFrom("example.org");
config.setServiceName(serviceName);
