我正在尝试为 Mule ESB 2.2.1 设置一个配置文件，将传入请求路由到另一个盒子。这似乎很简单，但我收到连接被拒绝的异常，我不知道为什么。
这是我的 Mule 配置文件中的模型：
<model name="ProxySample">
<service name="HttpProxyService">
<inbound>
<http:inbound-endpoint address="http://localhost:8787" synchronous="true"/>
</inbound>
<outbound>
<pass-through-router>
<outbound-endpoint address="http://server2.xyz.com:8080#[header:http.request]" synchronous="true"/>
</pass-through-router>
</outbound>
</service>
</model>
我正在浏览器中浏览http://localhost:8787/my-site，认为它会路由到http://server2.xyz.com:8080/my-site，但我收到连接被拒绝错误。
下面是 Mule 服务器的控制台输出：
