Eclipse获取表单参数

（1）新建一个.html file

源码：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>表单参数</title>
<style>
</style>
</head>
<body>
<form action="Lab4" method="post">
编号:<input type="text" name="number" value="002" size="2" /><hr>
用户名:<input type="text" name="username" placeholder="请输入用户名"><hr>
密码:<input type="password" name="password"value="11111111111"><hr>
性别:<input type="radio" name="sex" value="男" checked>男
<input type="radio" name="sex" value="女">女<hr>
部门:<select name="branch">
<option value="销售部" selected>销售部</option>
<option value="人事部">人事部</option>
</select><hr>
兴趣:<input type="checkbox" id="swimming" name="hobby" value="游泳"><label for="swimming">游泳</label> 
<input type="checkbox" id="sining" name="hobby" value="唱歌"><label for="sining">唱歌</label> 
<input type="checkbox" id="inter	net" name="hobby" value="上网"><label for="internet">上网</label>

<input type="submit" value="注册">
<input type="reset" value="重置">
</form>
</body>
</html>

（2）新建一个servlet

源码：

package Lab4Servlet;


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


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


/**
 * Servlet implementation class Lab4
 */
@WebServlet("/Lab4")
public class Lab4 extends HttpServlet {
	private static final long serialVersionUID = 1L;
       
    /**
     * @see HttpServlet#HttpServlet()
     */
    public Lab4() {
        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
		response.getWriter().append("Served at: ").append(request.getContextPath());
	}


	/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		request.setCharacterEncoding("utf-8");
		response.setCharacterEncoding("utf-8");
		response.setHeader("Content-type","text/html;charset=utf-8");
		
		String number = request.getParameter("number");
		String username = request.getParameter("username");
		String password = request.getParameter("password");
		String sex = request.getParameter("sex");
		String branch = request.getParameter("branch");
		String[] hobby = request.getParameterValues("hobby");
		String instrution = request.getParameter("instruction");
		PrintWriter out = response.getWriter();
		//out.println("number:"+number);
		String str = "<ol>";
		for(int i=0;i<hobby.length;i++){
			if(i<hobby.length - 1)
			{
				str +="<li>"+ hobby[i]+ "</li>";
			}else
			{
				str +="<li>"+ hobby[i]+"</li></ol>";
			}
		}
		out.println();
		out.println("编号："+number+"  <hr>用户名："+username+"   <hr>密码:"+password+"  <hr>性别："+sex+"  <hr>部门："+branch+"  <hr>兴趣： "+str+"  <hr>说明："+instrution);
		
	}


}
