一：用户注册信息页面(地址为级联) UserDetails.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 <s:fielderror></s:fielderror> 12 <form action="UserDetailsAction" method="post"> 13 用户名：<input type="text" name="username" /><br> 14 生日：<input type="text" name="birthday" />(格式为:yyyy-mm-dd)<br> 15 详细地址：<input type="text" name="address">省 16 <input type="text" name="address">市 17 <input type="text" name="address">区<br> 18 <input type="text" name="address"/> 19 <input type="submit" value="注册"> 20 </form> 21 </body> 22 </html>
二：在action写set get方法 nuc.sw.action--->UserDetailsAction.java
1 package nuc.sw.action; 2 import java.util.Date; 3 import com.opensymphony.xwork2.ActionSupport; 4 5 import nuc.sw.vo.Address; 6 public class UserDetailsAction extends ActionSupport{ 7 private String username; 8 //注意类型 9 private Date birthday; 10 //必须为Address类型。否则获取不到。 11 private Address address; 12 public Date getBirthday() { 13 return birthday; 14 } 15 public void setBirthday(Date birthday) { 16 this.birthday = birthday; 17 } 18 public String getUsername() { 19 return username; 20 } 21 public void setUsername(String username) { 22 this.username = username; 23 } 24 25 26 27 public Address getAddress() { 28 return address; 29 } 30 31 32 public void setAddress(Address address) { 33 this.address = address; 34 } 35 36 37 public String RegisterMethod() throws Exception { 38 return SUCCESS; 39 } 40 41 }
三：获取Address类型 所以写Address.java --->nuc.sw.vo
package nuc.sw.vo; public class Address { private String province; private String city; private String county; private String street; public Address(String province, String city, String county, String street) { super(); this.province = province; this.city = city; this.county = county; this.street = street; } public String getProvince() { return province; } public void setProvince(String province) { this.province = province; } public String getCity() { return city; } public void setCity(String city) { this.city = city; } public String getCounty() { return county; } public void setCounty(String county) { this.county = county; } public String getStreet() { return street; } public void setStreet(String street) { this.street = street; } }
四：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="true" /> 8 <package name="default" namespace="/" extends="struts-default"> 9 <action name="UserDetailsAction" class="nuc.sw.action.UserDetailsAction" method="RegisterMethod"> 10 <result>/showUserDetails.jsp</result> 11 <result name="input">/UserDetails.jsp</result> 12 </action> 13 </package> 14 </struts>
五：用户提交信息后进行显示 showUserDetails.jsp
生日的月份需要MM---mm指时间
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 用户名：<s:property value="username"/><br> 12 生日： <s:date name="birthday" format="yyyy-MM-dd"/><br> 13 您的详细地址为：<br> 14 <s:property value="address.province"/>省 15 <s:property value="address.city"/>市 16 <s:property value="address.county"/>区 17 <s:property value="address.street"/> 18 </body> 19 </html>
六：提交的地址信息为字符串String,最后要以对象的形式输出，所以需要自定义转换器
nuc.sw.action--->AddressConverter.java
1 package nuc.sw.action; 2 3 import java.util.Map; 4 5 import org.apache.struts2.util.StrutsTypeConverter; 6 import nuc.sw.vo.Address; 7 public class AddressConverter extends StrutsTypeConverter { 8 9 /* 10 *1:转换器必须继承StrutsTypeConverter 11 *2:自带方法 字符串转为value(address) 12 *3:自带方法 value转为字符串 13 */ 14 @Override 15 public Object convertFromString(Map arg0, String[] arg1, Class arg2) { 16 17 //此处可以简略代码，但是必须在Address.java写构造方法 18 Address address=new Address(arg1[0],arg1[1],arg1[2],arg1[3]); 19 20 //String[]中放Address中的4个值 21 // address.setProvince(arg1[0]); 22 // address.setCity(arg1[1]); 23 // address.setCounty(arg1[2]); 24 // address.setStreet(arg1[3]); 25 return address; 26 } 27 28 29 @Override 30 public String convertToString(Map arg0, Object arg1) { 31 //ag1是父类，Address是子类，需要强制转换。 32 if(arg1 instanceof Address){ 33 Address a=(Address)arg1; 34 return a.getProvince()+"省"+a.getCity()+"市"+a.getCounty()+"区"+a.getStreet(); 35 } 36 else 37 return null; 38 } 39 40 }
七：局部转换器 ---写action中属性名建的配置文件---和action位于同级目录下
1 address=nuc.sw.action.AddressConverter
八：项目结构：
九：运行结果：
