HTTPCLIENT4 Post XML to a server

Now the online httpclient is basically full 3.x version of the content, HttpClient4 API changes relative to 3 has changed a lot, HttpClient4 done a simple study, completed a HTTPCLIENT4 post XML function.

For the Post method, the first thought is the form submission, post XML naturally think of is to define a variable name, such as called XMLData, and then POST the value of this parameter, when the server received, naturally also through the Requset.getparameter (" XMLData ") way to receive.

Now what I'm going to do here is not by the way above, but by not specifying the parameter name to post, which is actually writing a stream to the request.

The following are the specific ways to implement:

1, Parameter name way post XML data

import org.apache.http.client.entity.UrlEncodedFormEntity;
Import Org.apache.http.client.methods.HttpPost;
