客户端HTTP发送xml报文，服务端接收报文并返回报文（不带验证）

服务端是一个简单的Servlet，需要配置web.xml

package com.servlet;

import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.Iterator;

import javax.servlet.GenericServlet;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import org.dom4j.io.XMLWriter;


public class MyServlet extends GenericServlet {

	@Override
	public void service(ServletRequest request, ServletResponse response)
			throws ServletException, IOException {
			
			System.out.println("------调用servlet -----");
			InputStream in = request.getInputStream();
	        SAXReader saxReader = new SAXReader();
	        InputStreamReader strInStream = new InputStreamReader(in, "UTF-8");
	        try {
	            Document document = saxReader.read(strInStream);
	            Element root = document.getRootElement(); //FILELIST
	            System.out.println("1、"+root.getName());
	            Iterator lv = root.elementIterator("FILE");
	            Element el = null;
	            while (lv.hasNext()) {
	                el = (Element) lv.next(); 
	                System.out.println("2、"+el.getName());
	                System.out.println("FILE_NAME="+el.elementText("FILE_STRING"));
	                System.out.println("FILE_NAME="+el.elementText("FILE_NAME"));
	                //逻辑处理
	            }
	            //String file = document.selectSingleNode("/FILE/FILE_STRING").getText();
	            //System.out.println(file);
	        } catch (DocumentException e) {
	            e.printStackTrace();
	        } 
	        
	        Document document = DocumentHelper.createDocument();
	        Element rootElement = document.addElement("RET_INFO");
	        rootElement.addElement("RESULT", "操作成功");
	        DataOutputStream out = new DataOutputStream(response.getOutputStream());
	        XMLWriter writer = new XMLWriter(out);
	        writer.write(document);
	        writer.close();
	        out.flush();

	}

}

 

客户端直接通过http请求的方式请求远程地址的servlet

package com.client;

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.XMLWriter;


public class TestMyServlet {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Document document = DocumentHelper.createDocument();
        Element rootElement = document.addElement("FILELIST");
        
        Element planElement = rootElement.addElement("FILE");
        planElement.addElement("FILE_STRING", "文件1");
        planElement.addElement("FILE_NAME", "名称1");
        
        Element planElement2 = rootElement.addElement("FILE");
        planElement2.addElement("FILE_STRING", "文件2");
        planElement2.addElement("FILE_NAME", "名称2");
        
        HttpURLConnection http;
        
        try {
            URL urls = new URL("http://localhost:8080/HttpWebServier/");
            http = (HttpURLConnection) urls.openConnection();
            http.setDoOutput(true);
            http.setDoInput(true);
            http.setRequestMethod("POST");
            DataOutputStream out = new DataOutputStream(http.getOutputStream());                
            XMLWriter writer = new XMLWriter(out);
            writer.write(document);
            writer.close();
            out.flush();
            
            //System.out.println( in(http.getInputStream()));
            //接口返回的报文
           
            String resp = "";
            java.io.BufferedReader breader = new BufferedReader(new InputStreamReader(http.getInputStream(), "UTF-8"));
		    String str = breader.readLine();
		    while (str != null) {
			    resp+=str;
			    str= breader.readLine();
		    }
   		 System.out.println("resp="+resp);  
            
        } catch (Exception ex) {
            ex.printStackTrace();
        }
	}

}

推荐可以通过Fiddler软件 自己拼接xml报文请求HTTP地址，报文格式如下：

<?xml version="1.0" encoding="UTF-8"?>
    <FILELIST>
      <FILE>
           <FILE_STRING>詹姆斯</FILE_STRING>
            <FILE_NAME>韦德</FILE_NAME>
      </FILE>
      <FILE>
           <FILE_STRING>科比</FILE_STRING>
            <FILE_NAME>鸟人</FILE_NAME>
      </FILE>
    </FILELIST>
