AbstractWizardFormController 实例

来源：互联网发布：mac安装mysql数据库编辑：程序博客网时间：2024/05/14 02:18

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>

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>

<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix">
   <value>/</value>
</property>
<property name="suffix">
   <value>.jsp</value>
</property>
</bean>

<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

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>

<html>
<head>
    <title>My JSP 'index.jsp' starting page</title>
</head>

<body>

<FORM action="hehe.htm" method="post" name="dsada">
<TABLE>
<TBODY>
   <TR>
    <TD>
     注册信息，请认真填写！
    <input type="submit" value="下一步" name="_target1" align="center"/>

</TD>
</TR>
</TBODY>
</TABLE>
</FORM>
<br>
</body>
</html>

6)register1.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

<html>
<head>
<title>My JSP 'second.jsp' starting page</title>

</head>

<body>
   <table>
   <TR>
      <TD>
       User infor:
      </TD>
     </TR>
     <TR>
      <TD>姓名：
       <c:out value="${registerInfor.name}" />
      </TD>
     </TR>
     <TR>
      <TD>年龄：
       <c:out value="${registerInfor.age}" />
      </TD>
     </TR>
     <TR>
      <TD>
      地址：
       <c:out value="${registerInfor.adress}" />
      </TD>
     </TR>
     <TR>
      <TD>email:
       <c:out value="${registerInfor.email}" />
      </TD>
     </TR>
      <TR>
      <TD>电话:
       <c:out value="${registerInfor.phone}" />
      </TD>
     </TR>
      <TR>
      <TD>喜好:
       <c:out value="${registerInfor.favor}" />
      </TD>
     </TR>




   </table>
</body>
</html>

7)register2.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>

<html>
<head>
<title>My JSP '2.jsp' starting page</title>

</head>

8)register3.jsp

<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>

<html>
<head>
<title>My JSP '3.jsp' starting page</title>

</head>

</body>
</html>

9)success.jsp

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

<html>
<head>
<title>My JSP 'second.jsp' starting page</title>

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！
