AbstractWizardFormController 实例

由于工作需要，需要经多个表单在最后一部进行操作，觉得spring的AbstractWizardFormController最适合在这里使用，我自己做的一个完整的小例子。以下是全部的代码：
1）配置文件：web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.3" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_3.xsd">

<servlet>
  <servlet-name>heheapp</servlet-name>
  <servlet-class>
   org.springframework.web.servlet.DispatcherServlet
  </servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
  <servlet-name>heheapp</servlet-name>
  <url-pattern>*.htm</url-pattern>
</servlet-mapping>

<taglib>
  <taglib-uri>http://java.sun.com/jstl/core</taglib-uri>
  <taglib-location>/WEB-INF/c.tld</taglib-location>
</taglib>
</web-app>


2)heheapp-servlet.xml
这个名字是由web.xml中的<servlet-name>属性来的，spring中是这样默认的。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
    "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="registerController" class="com.kang.test.RegisterController">
  <property name="successView"><value>success</value> </property>
  <property name="cancelView"><value>main</value> </property>
  <property name="commandClass"><value>com.kang.test.RegisterInfor</value></property>
  <property name="pages">
    <list>
   <value>main</value>
   <value>register1</value>
   <value>register2</value>
   <value>register3</value>
    </list>
     </property>
</bean>
<!--InternalResourceViewResolver-->
<bean id="viewResolver"
  class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="prefix">
   <value>/</value>
  </property>
  <property name="suffix">
   <value>.jsp</value>
  </property>
</bean>

<!--SimpleUrlHandlerMapping-->
<bean id="urlMapping"
  class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
   <props>
    <prop key="/hehe.htm">registerController</prop>
   </props>
  </property>
</bean>
</beans>
在这个配置文件里，所有的舰艇都来自web.xml文件，这里进一步进行监听，凡是以/hehe.htm作为提交目的的都将被registerController进行处理。

3)RegisterController

package com.kang.test;

import org.apache.log4j.Logger;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.validation.BindException;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractWizardFormController;

public class RegisterController extends AbstractWizardFormController {
/**
  * Logger for this class
  */
private static final Logger logger = Logger.getLogger(RegisterController.class);

private String successView;
private String cancelView;
    public RegisterController(){
    
     logger.info("--------RegisterController init----start--");
     //setPages(new String[] {"main.jsp", "register1.jsp", "register2.jsp", "register3.jsp"});
     //this.successView="success.jsp";
     //this.cancelView="main.jsp";    
     logger.info("--------RegisterController init----end----");
    
    }
public String getSuccessView() {
  logger.info("--------RegisterController getSuccessView()------");
  return successView;
}

public void setSuccessView(String successView) {
  this.successView = successView;
}

public String getCancelView() {
  logger.info("--------RegisterController getCancelView()------");
  return cancelView;
}

public void setCancelView(String cancelView) {
  this.cancelView = cancelView;
}

public  ModelAndView processFinish(HttpServletRequest req, HttpServletResponse res, Object command, BindException errs) throws Exception {
  logger.info("-----processFinish-----start-----");
  RegisterInfor registerInfor = (RegisterInfor) command;
  logger.info("-----processFinish-----registerInfor:"+registerInfor);
  logger.info("-----processFinish-----end-----");
  return new ModelAndView(this.getSuccessView(), "registerInfor", registerInfor);
}

public ModelAndView processCancel(HttpServletRequest req, HttpServletResponse res, Object command, BindException errs) throws Exception {
  logger.info("-----processCancel-----");
  return new ModelAndView(this.getCancelView());
}
}


4)RegisterInfor 是一个普通的bean，负责存贮整个流程中需要提交的信息，他在多个步骤中使用。

package com.kang.test;

import java.io.UnsupportedEncodingException;

import org.apache.log4j.Logger;

public class RegisterInfor {
/**
  * Logger for this class
  */
private static final Logger logger = Logger.getLogger(RegisterInfor.class);

private String name;

private int age;

private char sex;

private String adress;

private String phone;

private String email;

private String favor;
   
public RegisterInfor(){
  logger.info("--------RegisterInfor init------");
 
}
public String getAdress() {
  logger.info("--------getAdress()------");
  return adress;
}

public void setAdress(String adress) {
  logger.info("--------setAdress------adress:"+adress);
  this.adress = StringUtil.changeStringCharSet(adress, "ISO-8859-1", "GBK");
  logger.info("--------adress:"+this.adress); 
}

public int getAge() {
  logger.info("-------getAge-------");
  return age;
}

public void setAge(int age) {
  logger.info("-------setAge-------age:"+age);
  this.age = age;
}

public String getEmail() {
  logger.info("-------getEmail-------");
  return email;
}

public void setEmail(String email) {
  logger.info("-------setEmail-------email:"+email);
  this.email = email;
}

public String getFavor() {
  logger.info("-------getFavor-------");
  return this.favor;
}

public void setFavor(String favor) {
 
  this.favor=StringUtil.changeStringCharSet(favor, "ISO-8859-1", "GBK");
  logger.info("-------setFavor-------favor:"+this.favor);
 
}

public String getName() {
  logger.info("-------getName-------");
  return this.name;
}

public void setName(String name) {
 
  this.name = StringUtil.changeStringCharSet(name, "ISO-8859-1", "GBK");
  logger.info("-------setName-------name:"+this.name);
}

public String getPhone() {
  logger.info("--------getPhone------");
  return phone;
}

public void setPhone(String phone) {
  logger.info("-------setPhone-------phone:"+phone);
  this.phone = phone;
}

public char getSex() {
  logger.info("-------getSex-------");
  return sex;
}

public void setSex(char sex) {
  logger.info("-------setSex-------sex:"+sex);
  this.sex = sex;
}
}

5）mian.jsp

      </TD>
     </TR>  
     
    
  
  
   </table>
  </body>
</html>

10）还有个字符处理的方法：

package com.kang.test;

import java.io.UnsupportedEncodingException;

public class StringUtil {

public static String changeStringCharSet(String str,String oldCharSet,String toCharSet){
  String temp="";
  try {
   temp = new String(str.getBytes(oldCharSet),toCharSet);
  } catch (UnsupportedEncodingException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  return temp;
}
}


全部的代码，发布以下就可以运行！呵呵！
