失败原因:de.measite.minidns.hla.ResolutionUnsuccessfulException:询问xxxx.在AAAA中产生错误响应NX_DOMAIN [英] failed because: de.measite.minidns.hla.ResolutionUnsuccessfulException: Asking for xxxx. IN AAAA yielded an error response NX_DOMAIN

问题描述

将smack升级到4.2.0之后，我遇到了连接问题.

After I upgraded smack to 4.2.0 I am getting connection issue.

The following addresses failed: 'xxxx:5222' failed because: 

de.measite.minidns.hla.ResolutionUnsuccessfulException: Asking for xxxx.    IN  A yielded an error response NX_DOMAIN, '52.90.233.38:5222' failed because: de.measite.minidns.hla.ResolutionUnsuccessfulException: Asking for xxxx. IN  AAAA yielded an error response NX_DOMAIN

在连接配置构建器中设置主机时会发生此问题.

the issue happen when host is set in connection configuration builder.

示例:

.setHost(ServiceConstants.CHAT_SERVER)

请参见 https://github.com/igniterealtime/Smack/wiki/Smack-4.2-Readme-and-Upgrade-Guide

这是我的最终配置，在达沃德·法拉哈蒂(Davood Falahati)帮助下有效！

This is my final configuration, it worked after Davood Falahati help !

InetAddress inetAddress = InetAddress.getByName(ServiceConstants.CHAT_SERVER);
            XMPPTCPConnectionConfiguration.Builder builder = XMPPTCPConnectionConfiguration.builder()
                    .setXmppDomain(JidCreate.from(ServiceConstants.CHAT_SERVER).asDomainBareJid())
                    .setPort(5222)
                    .setHostAddress(inetAddress)
                    .setDebuggerEnabled(true)
                    .setSendPresence(true)

推荐答案

当未在本地DNS中配置xmpp服务器时，此问题主要发生在本地网络中.要解决该问题，请明确寻址xmpp服务器并使用

This problem mainly occurs in local networks when the xmpp server is not configured in local DNS. To solve the problem, explicitly address the xmpp server and use

setHostAddress(InetAddress地址)
