Servlet3.0新特性---Servlet路径问题

以前一直用的JDK6+Servlet2.0，

最近改前端开发了，但是对Java仍旧情有独钟，下载了新的JDK7，想玩玩Spring MVC结果发现从Servlet3.0以后支持注解

 

package com.servlet;

import java.io.IOException;
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 TestServlet
 */
@WebServlet("/test")
public class TestServlet extends HttpServlet {
	private static final long serialVersionUID = 1L;

	/**
	 * @see HttpServlet#HttpServlet()
	 */
	public TestServlet() {
		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
		doPost(request, response);
	}

	/**
	 * @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");
		String name = request.getParameter("name");
		String age = request.getParameter("age");

		if ("".equals(name) || "".equals(age)) {
			response.sendRedirect("failed.jsp");
		} else {
			response.sendRedirect("success.jsp");
		}
	}
}

 

方式设置URLPartten,虽然感觉在抄袭Spring，但是这样的确减少了WEB.XML内容，我个人比较喜欢！哈哈，在此记一笔，日后再更新其他好玩的特性，\(^o^)/~

 

顺便也把前端页面放这，对比着看：

<form action="test">
		<table>
			<tbody>
				<tr>
					<td><label for="name">姓名：</label></td>
					<td><input type="text" name="name" /></td>
				</tr>
				<tr>
					<td><label for="age">年龄：</label></td>
					<td><input type="number" name="age" min=0 max=150 /></td>
				</tr>
				<tr>
					<td><input type="submit" value="提交" /></td>
				</tr>
			</tbody>
		</table>
	</form>
