利用AJax方式提交和Webservice完成页面输入汉字简体字回显繁体字

最近一直在学习新的东西，当然也在回顾一些老的知识点。本博客涉及的主要是webservice的调用和Ajax底层的知识的应用，做了一个在页面输入中文的简体字，Ajax方式异步的调用后台webservice服务的小工程，仅作为老知识的回顾和新知识的学习，当然我主要是为了学习webservice的调用，好了，废话不多说，直接上代码吧。

 

首先index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
	pageEncoding="UTF-8"%>














	
Start typing a name in the input field below:

	

		Simple Chinese: 
	
	

		Traditional Chinese: 
	

 

接着后台的Servlet,就一个简单的servlet，所以就直接写了。

package com.fit.test01;

import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class SimpleToTraditionalServlet
 */
public class SimpleToTraditionalServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;

	/**
	 * @see HttpServlet#HttpServlet()
	 */
	public SimpleToTraditionalServlet() {
		super();
		// TODO Auto-generated constructor stub
	}

	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse
	 *      response)
	 */
	protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		this.doPost(request, response);
	}

	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse
	 *      response)
	 */
	protected void doPost(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {

		// System.out.println("----------------------------------------");
		request.setCharacterEncoding("utf-8");
		response.setContentType("text/html; charset=UTF-8");

		String param = request.getParameter("transferContent");
		System.out.println("---------------------" + param);
		String result = "";

		try {
			result = new Simple2TraditionalServiceImpl()
					.getTraditionalChinese(param);
		} catch (Exception e) {
			e.printStackTrace();
		}

		OutputStream os = response.getOutputStream();

		OutputStreamWriter osw = new OutputStreamWriter(os, "utf-8");

		osw.write(result);

		osw.flush();

		osw.close();

		// System.out.println("===================================" + result);
	}

}

 

后台调用Webservice的service，（当然我直接用了一个网站提供的Webservice服务，主义此网站提供的服务仅供学习使用，不能作为商业用途。）

package com.fit.test01;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.net.URL;
import java.net.URLConnection;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

public class Simple2TraditionalServiceImpl {

	private String buildSOAPString(String content) {
		StringBuilder sb = new StringBuilder();

		sb.append("")
				.append("")
				.append("")
				.append("")
				.append("").append(content).append("")
				.append("").append("")
				.append("");

		return sb.toString();
	}

	private InputStream sendSOAPMessage(String content) throws IOException {

		String soapMessage = this.buildSOAPString(content);
		URL url = new URL(
				"http://webservice.webxml.com.cn/WebServices/TraditionalSimplifiedWebService.asmx");

		URLConnection conn = url.openConnection();

		conn.setUseCaches(false);
		conn.setDoInput(true);
		conn.setDoOutput(true);

		conn.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
		conn.setRequestProperty("Content-Length",
				String.valueOf(soapMessage.length()));
		conn.setRequestProperty("SOAPAction",
				"http://webxml.com.cn/toTraditionalChinese");

		OutputStream os = conn.getOutputStream();

		OutputStreamWriter osw = new OutputStreamWriter(os, "utf-8");

		osw.write(soapMessage);
		osw.flush();

		osw.close();

		InputStream is = conn.getInputStream();

		return is;

	}

	public String getTraditionalChinese(String content) throws Exception {

		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

		DocumentBuilder builder = factory.newDocumentBuilder();

		InputStream is = null;
		String result = "";
		try {
			is = sendSOAPMessage(content);

			Document doc = builder.parse(is);

			NodeList nodeList = doc
					.getElementsByTagName("toTraditionalChineseResult");

			for (int i = 0; i < nodeList.getLength(); i++) {
				Node node = nodeList.item(i);
				result = node.getFirstChild().getNodeValue();
				System.out.println(node.getFirstChild().getNodeValue());
			}
		} catch (Exception e) {
			throw e;
		} finally {
			if (is != null) {
				is.close();
			}
		}

		return result;
	}

	public static void main(String[] args) throws Exception {
		new Simple2TraditionalServiceImpl().getTraditionalChinese("���յ�");
	}
}
