Spring RestTemplate Client - connection refused exception
提问by PST
I am new to webservices and trying to write a RESTFul webservice's client using RestTemplate. I am using org.springframework.http.converter.xml.MarshallingHttpMessageConverter as message converter and org.springframework.oxm.xstream.XStreamMarshaller as marshaller.
我是网络服务的新手，并尝试使用 RestTemplate 编写 RESTFul 网络服务的客户端。我使用 org.springframework.http.converter.xml.MarshallingHttpMessageConverter 作为消息转换器和 org.springframework.oxm.xstream.XStreamMarshaller 作为编组器。
Is there any way to debug this further or find out the root cause of this issue?

the webServiceURL you are trying to call is not reachable. Ensure the webServiceURL path is correct and is listening.
您尝试调用的 webServiceURL 无法访问。确保 webServiceURL 路径正确且正在侦听。
PS. Also check if there is some firewall issue at Server side.
附注。还要检查服务器端是否存在一些防火墙问题。
Wireshark may help you to debug further.
