篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了struts2-12-用户自定义转换器(地址)相关的知识,希望对你有一定的参考价值。

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&nbsp;&nbsp;&nbsp;&nbsp;码:<input type="text" name="password"><br>
29   详细地址:<input type="text" name="address">&nbsp;&nbsp;
30         <input type="text" name="address">&nbsp;&nbsp;
31         <input type="text" name="address"><br>
32         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
33         &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
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()">&nbsp;&nbsp;&nbsp;
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">&nbsp;&nbsp;
15                <input type="text" name="address">&nbsp;&nbsp;
16                <input type="text" name="address"><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>
