通过Mule ESB CE连接Ejabbered CE

Question

我试图把Ejabberd服务器放在Mule ESB社区版的后面，这意味着所有到Ejabberd服务器的消息必须首先进入ESB。

我用了XMPP连接器在文件中如下XML配置：

<?xml version="1.0" encoding="UTF-8"?> 
<mule xmlns="http://www.mulesoft.org/schema/mule/core" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:spring="http://www.springframework.org/schema/beans" 
    xmlns:xmpp="http://www.mulesoft.org/schema/mule/xmpp" 
    xmlns:stdio="http://www.mulesoft.org/schema/mule/stdio" 
    xsi:schemaLocation=" 
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd 
    http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/3.1/mule.xsd 
    http://www.mulesoft.org/schema/mule/xmpp http://www.mulesoft.org/schema/mule/xmpp/3.1/mule-xmpp.xsd 
    http://www.mulesoft.org/schema/mule/stdio http://www.mulesoft.org/schema/mule/stdio/3.1/mule-stdio.xsd"> 

    <xmpp:connector name="xmppConnector" host="192.168.1.132" port="5222" user="whh@whh.com" password="password"/> 

    <flow name="stdio2xmpp"> 
     <stdio:inbound-endpoint system="IN"/> 
     <xmpp:outbound-endpoint type="CHAT" recipient="sjc@whh.com"/> 
    </flow> 

    <flow name="xmpp2stdio"> 
     <xmpp:inbound-endpoint type="CHAT" from="sjc@whh.com"/> 
     <xmpp:xmpp-to-object-transformer/> 
     <stdio:outbound-endpoint system="OUT"/> 
    </flow> 
</mule> 

我敢肯定，用户名和密码是正确的，因为我可以用洋泾浜用它登录服务器。当我试图在studio中运行这个流程时，它总是抛出异常“未连接到服务器”。

任何人都有这个问题的想法？谢谢。

mule它建立在Smack的顶部，可能会遇到建立连接的问题。

你能证实xmpp服务器启动吗？一旦你知道它继续并调试Smack。 Smack连接init只捕获可能抛出异常的子集。 例如它会忽略NPE并在OK中声明连接。 它也不是线程安全的，所以只有一个连接到xmpp服务器的原型。
