how to set proxy server details on WebServiceTemplate

Question

I have a SOAP webservice endpoint url(let\'s say :\"EP1\") which we can connect only through a proxy server.

We are using org.springframework.ws

Answer 1

You must use VM arguments: -Dhttp.proxyHost=mydomain.com -Dhttp.proxyPort=8080

Having in mind that this setting applies to all HTTP requests made from Java.

Answer 2

You can specify custom HttpClient via HttpComponentsMessageSender when constructing the WebServiceTemplate. You can then pass default request config which includes the proxy to the client. Something like this should work:

RequestConfig config = RequestConfig
        .custom()
        .setProxy(new HttpHost("host"))
        .build();

CloseableHttpClient client = HttpClients
        .custom()
        .setDefaultRequestConfig(config)
        .build();

HttpComponentsMessageSender messageSender = new HttpComponentsMessageSender(client);

WebServiceTemplate wsTemplate = new WebServiceTemplate();
wsTemplate.setMessageSender(messageSender);
// Set other required properties ...

You might need to set other properties on the WebServiceTemplate object or the HttpClient depending on your needs so on. But this should demonstrate the basic concept.

Also take a look at this sample illustrating the usage of proxies in Apache HTTP client.
