基于httpclient 2.0 final的demo(for jdk1.5/1.6):

基于httpclient 4.x的demo

import org.apache.http.client.methods.HttpPost;import org.apache.http.impl.client.HttpClients;import org.apache.http.HttpEntity;import org.apache.http.HttpResponse;import org.apache.http.impl.client.CloseableHttpClient;import org.apache.http.util.EntityUtils;import org.apache.http.entity.ByteArrayEntity;public class Test{    public static void main(String[] args) throws Exception    {        post();    }    public static void  post() throws Exception{        //HttpClient client = new DefaultHttpClient();        CloseableHttpClient client = HttpClients.createDefault();        HttpPost post = new HttpPost("http://xxx.xxx.xxx/csc/maintaining_info");        String xml = "
     
      xxxx
     ";        HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));        post.setEntity(entity);        HttpResponse response = client.execute(post);        String result = EntityUtils.toString(response.getEntity());        System.out.println(result);    }}

 

后记：

基于历史jar包来写代码时，首先忘掉需求。

先去看对应版本的doc。 然后反过来再写！

否则很房费时间！

 

选对版本，选对文档，java也可以简单暴力！
