一：登录主页面--->login
根据登录注册的不同按钮进入不同的action及method
1 <%@ page language="java" contentType="text/html; charset=utf-8"
2 pageEncoding="utf-8"%>
3 <%@ taglib prefix="s" uri="/struts-tags"%>
4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
5 <html>
6 <head>
7 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
8 <title>登录页面</title>
9 <script>
10 function login(){
11 targetForm=document.forms[0];
12 targetForm.action="Login!LoginMethod";
13 targetForm.submit();
14 }
15 function register(){
16 targetForm=document.forms[0];
17 targetForm.action="Register!RegisterMethod";
18 targetForm.submit();
19 }
20 </script>
21 </head>
22
23 <body>
24 <s:fielderror escape="false"></s:fielderror>
25 <font color="red">${requestScope.error}</font>
26 <form action="actionName!methodName" method="post" >
27 用户名：<input type="text" name="username"><br>
28 密 码：<input type="text" name="password"><br>
29 详细地址：<input type="text" name="address">省
30 <input type="text" name="address">市
31 <input type="text" name="address">区<br>
32
33
34 <input type="text" name="address"/><br>
35 用户类型:
36 <select name="usertype">
37 <option value="管理员" >管理员</option>
38 <option value="普通用户">普通用户</option>
39 </select>
40 <br/>
41 <input type="button" value="登录" onclick="login()">
42 <input type="button" value="注册" onclick="register()">
43 </form>
44 </body>
45 </html>
二：注册页面--->register.jsp
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <%@ taglib prefix="s" uri="/struts-tags"%> 4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 5 <html> 6 <head> 7 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 8 <title>注册页面</title> 9 </head> 10 <body> 11 <form action="Register" method="post"> 12 用户名：<input type="text" name="username" /><br> 13 密码：<input type="password" name="password" /><br> 14 详细地址：<input type="text" name="address">省 15 <input type="text" name="address">市 16 <input type="text" name="address">区<br> 17 <input type="text" name="address"/> 18 <input type="submit" value="注册"> 19 </form> 20 </body> 21 </html>
三：用户登录成功页面 --->adminWelcome.jsp
1 <%@ page language="java" contentType="text/html; charset=utf-8"
2 pageEncoding="utf-8"%>
3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4 <html>
5 <head>
6 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
7 <title>Insert title here</title>
8 </head>
9 <body>
10 欢迎${sessionScope.loginType}${sessionScope.loginUser}<a href="login.jsp">登录!</a><br>
11
12 </body>
13 </html>
四：用户个人的相关信息 nuc.sw.vo.User.java
1 package nuc.sw.vo;
2
3 public class User {
4 private String username;
5 private String password;
6 private String usertype;
7 private Address address;
8 public Address getAddress() {
9 return address;
10 }
11 public void setAddress(Address address) {
12 this.address = address;
13 }
14 public String getUsername() {
15 return username;
16 }
17 public void setUsername(String username) {
18 this.username = username;
19 }
20 public String getPassword() {
21 return password;
22 }
23 public void setPassword(String password) {
24 this.password = password;
25 }
26 public String getUsertype() {
27 return usertype;
28 }
29 public void setUsertype(String usertype) {
30 this.usertype = usertype;
31 }
32
33 }
五：地址是四级联为了简化应使用一个变量来获取四个值 nuc.sw.vo--->Address.java
1 package nuc.sw.vo;
2
3 public class Address {
4
5 private String province;
6 private String city;
7 private String county;
8 private String street;
9
10 public String getProvince() {
11 return province;
12 }
13
14 public void setProvince(String province) {
15 this.province = province;
16 }
17
18 public String getCity() {
19 return city;
20 }
21
22 public void setCity(String city) {
23 this.city = city;
24 }
25
26 public String getCounty() {
27 return county;
28 }
29
30 public void setCounty(String county) {
31 this.county = county;
32 }
33
34 public String getStreet() {
35 return street;
36 }
37
38 public void setStreet(String street) {
39 this.street = street;
40 }
41
42 }
六：现将地址转换，需加一个 文件：xwork-conversion.properties
1 nuc.sw.vo.Address=nuc.sw.utils.MyTypeConverter
七：在工具类中设置地址的值 --->nuc.sw.utils MyTypeConverter
1 package nuc.sw.utils;
2
3 import java.util.Map;
4
5 import org.apache.struts2.util.StrutsTypeConverter;
6
7 import nuc.sw.vo.Address;
8
9 public class MyTypeConverter extends StrutsTypeConverter {
10
11 @Override
12 public Object convertFromString(Map context, String[] values, Class toClass) {
13
14 Address address = new Address();
15 address.setProvince(values[0]);
16 address.setCity(values[1]);
17 address.setCounty(values[2]);
18 address.setStreet(values[3]);
19 return address;
20 }
21
22 @Override
23 public String convertToString(Map context, Object o) {
24
25 return null;
26 }
27
28 }
八：nuc.sw.action--->LoginRegAction.java
在相关的Action中执行相应方法并且配置相应的存储区域以便获取
1 package nuc.sw.action;
2
3 import com.opensymphony.xwork2.ActionContext;
4 import com.opensymphony.xwork2.ActionSupport;
5 import com.opensymphony.xwork2.ModelDriven;
6
7 import nuc.sw.vo.User;
8
9 public class LoginRegAction extends ActionSupport implements ModelDriven<User>{
10 private User user=new User();
11 public User getModel() {
12 return user;
13 };
14 public String LoginMethod() throws Exception {
15 //登录逻辑
16 if(user.getUsername().equals("张丹")&&user.getPassword().equals("123")){
17 ActionContext.getContext().getSession().put("loginUser",user.getUsername());
18 ActionContext.getContext().getSession().put("loginType",user.getUsertype());
19 return SUCCESS;
20 }
21 else{
22 ActionContext.getContext().put("error", "用户名或者密码错误");
23 return ERROR;
24 }
25 }
26 public String RegisterMethod() throws Exception {
27 ActionContext.getContext().getSession().put("registerUser", user.getUsername());
28 ActionContext.getContext().getSession().put("registerProvince",user.getAddress().getProvince());
29 ActionContext.getContext().getSession().put("registerCity",user.getAddress().getCity());
30 ActionContext.getContext().getSession().put("registerCounty",user.getAddress().getCounty());
31 ActionContext.getContext().getSession().put("registerStreet",user.getAddress().getStreet());
32 return SUCCESS;
33 }
34
35 }
九：配置struts.xml
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 4 "http://struts.apache.org/dtds/struts-2.3.dtd"> 5 6 <struts> 7 <constant name="struts.devMode" value="false" /> 8 <constant name="struts.enable.DynamicMethodInvocation" value="true"></constant> 9 <package name="default" namespace="/" extends="struts-default"> 10 <action name="Login" method="LoginMethod" class="nuc.sw.action.LoginRegAction"> 11 <result name="success">/adminWelcome.jsp</result> 12 <result name="error">/login.jsp</result> 13 <result name="input">/login.jsp</result> 14 </action> 15 <action name="Register" method="RegisterMethod" class="nuc.sw.action.LoginRegAction"> 16 <result name="success">/regLogin.jsp</result> 17 <result name="error">/register.jsp</result> 18 <result name="input">/register.jsp</result> 19 </action> 20 </package> 21 </struts>
十：注册成功后，显示注册地址信息--->regLogin.jsp
可通过EL表达式/OGNL表达式获取相关值
1 <%@ page language="java" contentType="text/html; charset=utf-8"
2 pageEncoding="utf-8"%>
3 <%@ taglib prefix="s" uri="/struts-tags"%>
4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
5 <html>
6 <head>
7 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
8 <title>注册成功后登录</title>
9 </head>
10 <body>
11 欢迎${sessionScope.registerUser}注册,<a href="login.jsp">请登录!</a><br>
12 您的详细地址为：<br>
13 ${sessionScope.registerProvince}
14 ${sessionScope.registerCity}
15 <s:property value="#session.registerCounty"/>
16 <s:property value="#session.registerStreet"/>
17 </body>
18 </html>
