java apache xml servlet javaee

1、パラメータ名方式POST XMLデータ

import org.apache.http.*; 
import org.apache.http.client.entity.UrlEncodedFormEntity; 
import org.apache.http.client.methods.HttpPost; 
import org.apache.http.impl.client.DefaultHttpClient; 
import org.apache.http.message.BasicNameValuePair; 
import org.apache.http.client.*; 

import java.io.IOException; 
import java.io.InputStreamReader; 
import java.io.UnsupportedEncodingException; 
import java.util.*; 

/** 
*           POST XML 
* 
* @author leizhimin 2010-7-8 22:29:28 
*/ 
public class TestPost { 
        public static void main(String[] args) throws IOException { 
                HttpClient httpclient = new DefaultHttpClient(); 
                HttpPost httppost = new HttpPost("http://localhost:8080/waitsrv/GenXmlServlet"); 

                List<NameValuePair> formparams = new ArrayList<NameValuePair>(); 
                formparams.add(new BasicNameValuePair("xmldate", "<html>    </html>")); 
                formparams.add(new BasicNameValuePair("info", "xxxxxxxxx")); 
                UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formparams, "GBK"); 
//                entity.setContentType("text/xml; charset=GBK"); 
                httppost.setEntity(entity); 
                HttpResponse response = httpclient.execute(httppost); 
                HttpEntity resEntity = response.getEntity(); 
                InputStreamReader reader = new InputStreamReader(resEntity.getContent(), "ISO-8859-1"); 
                char[] buff = new char[1024]; 
                int length = 0; 
                while ((length = reader.read(buff)) != -1) { 
                        System.out.println(new String(buff, 0, length)); 
                        httpclient.getConnectionManager().shutdown(); 
                } 
        } 
}

2、パラメータ名を指定しない方式でPOSTデータを作成する

import org.apache.http.HttpEntity; 
import org.apache.http.HttpResponse; 
import org.apache.http.NameValuePair; 
import org.apache.http.client.HttpClient; 
import org.apache.http.client.entity.UrlEncodedFormEntity; 
import org.apache.http.client.methods.HttpPost; 
import org.apache.http.impl.client.DefaultHttpClient; 
import org.apache.http.message.BasicNameValuePair; 
import org.apache.http.entity.*; 


import java.io.IOException; 
import java.io.InputStreamReader; 
import java.util.ArrayList; 
import java.util.List; 

/** 
*           POST   
* 
* @author leizhimin 2010-7-8 3:22:53 
*/ 
public class TestPostXml { 
        public static void main(String[] args) throws IOException { 
                HttpClient httpclient = new DefaultHttpClient(); 
                HttpPost httppost = new HttpPost("http://localhost:8080/waitsrv/GenXmlServlet"); 
                StringEntity myEntity = new StringEntity("<html>    </html>", "GBK"); 
                httppost.addHeader("Content-Type", "text/xml"); 
                httppost.setEntity(myEntity); 
                HttpResponse response = httpclient.execute(httppost); 
                HttpEntity resEntity = response.getEntity(); 
                InputStreamReader reader = new InputStreamReader(resEntity.getContent(), "ISO-8859-1"); 
                char[] buff = new char[1024]; 
                int length = 0; 
                while ((length = reader.read(buff)) != -1) { 
                        System.out.println(new String(buff, 0, length)); 
                } 
                httpclient.getConnectionManager().shutdown(); 
        } 
}
