AbstractWizardFormController example in Spring 2.5 Web MVC
Spring Web MVC provides AbstractWizardFormController class that
handle wizard form. In this tutorial, we will used
AbstractWizardFormController class. The AbstractWizardFormController
class provide us to store and show the forms data with multiple pages. It manage
the navigation between pages and validate the user input data form a single page
of the whole model object at once. In this tutorial we will discuss about this
controller.
Step 1:
Now we will create a index.jsp inside the WebContent folder. It will have a
hyperlink "AbstractWizardFormController Test Application". If user
click on this link request will generate. The code of the index.jsp
is:
|
<%@page
contentType="text/html"
pageEncoding="UTF-8"%>
<html>
<head>
<title>AbstractWizardFormController
Example</title>
</head>
<body>
<center>
<a
href="user1.html">
AbstractWizardFormController Test Application</a><br/>
</center>
</body>
</html>
|
Step 2:
Now we will configured web.xml for DispatcherServlet and spring.tld. The code of the
web.xml file is:
|
<?xml
version="1.0"
encoding="UTF-8"?>
<web-app
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns=
"http://java.sun.com/xml/ns/j2ee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_5.xsd"
version="2.5">
<servlet>
<servlet-name>dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcher</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<taglib>
<taglib-uri>/spring</taglib-uri>
<taglib-location>/WEB-INF/spring.tld</taglib-location>
</taglib>
</web-app>
|
Step 3:
Now we will create dispatcher-servlet.xml file in the /WEB-INF/ folder. The
dispatcher-servlet.xml file contain urlMapping, viewResolver for the all
requests. we will configure the AWizardFormController for this application. User
can see the code tin the dispatcher-servlet.xml file. the full code of the
dispatcher-servlet.xml is:
|
<?xml
version="1.0"
encoding="UTF-8"?>
