用Servlet获得界面中用户填写的信息

建立一个html网页让用户输入姓名、爱好等信息，然后传给servlet，最终展示出来。

package www.kale.com;

import java.io.IOException;
import java.io.PrintWriter;

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

public class Servlet extends HttpServlet {

	
	public Servlet（） {
		super（）;
	}

	public void doGet（HttpServletRequest request HttpServletResponse response）
			throws ServletException IOException {
			this.doPost（request response）;
	}

	public void doPost（HttpServletRequest request HttpServletResponse response）
			throws ServletException IOException {

		response.setContentType（“text/html;charset=UTF-8“）;
		request.setCharacterEncoding（“UTF-8“）;
		PrintWriter out = response.getWriter（）;
		
		String username = request.getParameter（“username“）;
