Servlet的代码：

import java.io.IOException;

import java.io.PrintWriter;

import java.net.URLEncoder;



import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



import com.zf.entity.GoodsDetail;



public class WeiDaoServlet extends HttpServlet {



	/**

	 * The doGet method of the servlet. <br>

	 * 

	 * This method is called when a form has its tag value method equals to get.

	 * 

	 * @param request

	 *            the request send by the client to the server

	 * @param response

	 *            the response send by the server to the client

	 * @throws ServletException

	 *             if an error occurred

	 * @throws IOException

	 *             if an error occurred

	 */

	public void doGet(HttpServletRequest request, HttpServletResponse response)

			throws ServletException, IOException {

		request.setCharacterEncoding("UTF-8");

		String username = request.getParameter("name");

		if (username.equals("zhangfan")) {

			/*

			StringBuilder builder = new StringBuilder();

			builder.append('{');

			builder.append("name:").append("zhangfan").append(",").append("age:").append(22);

			builder.append('}');

			System.out.println("builder" + builder);

			request.setAttribute("json", builder.toString());

			request.getRequestDispatcher("/MyJsp.jsp").forward(request, response);

			*/

			String str = "张三";

			response.getOutputStream().write(str.getBytes("GBK"));

//			str = URLEncoder.encode(str, "UTF-8");

//			response.getWriter().println(str);

		}

	}



	/**

	 * The doPost method of the servlet. <br>

	 * 

	 * This method is called when a form has its tag value method equals to

	 * post.

	 * 

	 * @param request

	 *            the request send by the client to the server

	 * @param response

	 *            the response send by the server to the client

	 * @throws ServletException

	 *             if an error occurred

	 * @throws IOException

	 *             if an error occurred

	 */

	public void doPost(HttpServletRequest request, HttpServletResponse response)

}

Android端的代码:

public void onClick(View v) {

				// TODO Auto-generated method stub

				new Thread()

				{

					public void run(){

						DefaultHttpClient client = new DefaultHttpClient();

						HttpPost post = new HttpPost("http://192.168.191.1:8080/WeiDaoHouTai/servlet/WeiDaoServlet?name=zhangfan");

//						post.getParams().setParameter("", "UTF-8");

						try {

							HttpResponse response = client.execute(post);

							if(response.getStatusLine().getStatusCode()==200) {

//								Toast.makeText(HomeActivity.this, "成功", Toast.LENGTH_SHORT).show();

//								response.

								HttpEntity entity = response.getEntity();

								String msg = EntityUtils.toString(entity);

								Log.d("zf", "entity = " + msg);

							}

						} catch (ClientProtocolException e) {

							// TODO Auto-generated catch block

							e.printStackTrace();

						} catch (IOException e) {

							// TODO Auto-generated catch block

							e.printStackTrace();

						}

					}

				}.start();

//				DefaultHttpClient client = new DefaultHttpClient();

//				HttpPost post = new HttpPost("http://192.168.1.103:8080/WeiDaoHouTai/servlet/WeiDaoServlet?name=zhangfan");

//				try {

//					HttpResponse response = client.execute(post);

//					if(response.getStatusLine().getStatusCode()==200) {

//						Toast.makeText(HomeActivity.this, "成功", Toast.LENGTH_SHORT).show();

//					}

//				} catch (ClientProtocolException e) {

//					// TODO Auto-generated catch block

//					e.printStackTrace();

//				} catch (IOException e) {

//					// TODO Auto-generated catch block

//					e.printStackTrace();

//				}
