Struts 2框架创建的第一个项目
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
創(chuàng)建我的第一個Struts 2項(xiàng)目。
用Struts 2框架創(chuàng)建一個簡單的WEB項(xiàng)目。
效果演示
登錄頁面
登陸成功之后顯示的頁面
在程序正式開始之前注意引入架包（注意：架包放在WEB-INF下面的lib包里）
Struts 2一共有13個架包如下圖所示
在開始我們的代碼之前看一下目錄結(jié)構(gòu)
代碼演示
1.UserAction.java
package com.hnpi.action;public class UserAction {private String name;private String pwd;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public String login(){System.out.println(name+":"+pwd);return "success";}}2.LoginServlet.java
package com.hnpi.servlet;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 LoginServlet extends HttpServlet {public void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {doPost(request, response);}public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {request.setCharacterEncoding("utf-8");response.setCharacterEncoding("utf-8");String name = request.getParameter("name");String pwd = request.getParameter("pwd");System.out.println(name+":"+pwd);PrintWriter out = response.getWriter();out.print("success");}}3.struts.xml
