New & Updated…
2. Handler Mapping
Define how web request (URL) maps to the Controller handlers.
- BeanNameUrlHandlerMapping example
Maps the requested URL to the name of the cocntroller. - ControllerClassNameHandlerMapping example
Uses convention to map the requested URL to Controller. - SimpleUrlHandlerMapping example
Allow developer to specify the mapping of URL patterns and handler mappings explicitly. - Configure the handler mapping priority
If multiple view handler mappings are applied, you have to declare priority to avoid conflict issue.
3. Controller
Controller class to handle the web request.
- MultiActionController example
Group related actions into a single controller class. - MultiActionController annotation example
Multi-actions controller by using annotation, @RequestMapping, he best and easy solution. - PropertiesMethodNameResolver example
A flexible method name resolver for the MultiActionController controller class, it allow to define the mapping between requested URL and method name explicitly. - ParameterMethodNameResolver example
Another method name resolver for the MultiActionController controller class, it allow to map URL to method name via requested parameter name. - ParameterizableViewController example
With ParameterizableViewController, you don’t need to hard code the view name in the controller class anymore, instead, you specify the view name through the ParameterizableViewController’s “viewName” property.
4. View Resolver
Resolve “view name” that returned from the controller class to a physical view page or JSP page.
- InternalResourceViewResolver example
Adding a predefined prefix and suffix to the view name (prefix + view name + suffix), and generate the final view page URL. - XmlViewResolver example
Puts view beans in XML file. - ResourceBundleViewResolver example
Puts view beans in “.properties” file. - Configure multiple view resolvers priority
If multiple view resolver strategies are applied, you have to declare priority to avoid conflict issue.
5. Form Handling
Form handling in Spring MVC.
- Form handling example
Form handling in Spring MVC, XML based version. - Form handling annotation example
Form handling in Spring MVC, annotation version. - Handling duplicate form submission
“Post/Redirect/Get” Design Pattern is the common solution for this duplicated form submission problem. - RedirectView example
A view which redirect to another absolute, context relative, or current request relative URL. - Handling multipage / wizard forms
How to handle multipage forms or wizard form.
6. Spring’s Form Tag Library
Render HTML form’s components via Spring’s form tag.
- Textbox example
<form:input /> tag, render a HTML textbox field. - Password example
<form:password /> tag, render a HTML password field. - Textarea example
<form:textarea /> tag, render a HTML textarea field. - Checkbox and Checkboxes example
<form:checkbox />, <form:checkboxes /> tags, render a single or multiple HTML check boxes. - Radiobutton and Radiobuttons example
<form:radiobutton />, <form:radiobuttons /> tags, render a single or multiple HTML radio buttons. - Dropdown and list box example
<form:select />, <form:option /> and <form:options /> tags, render a HTML dropdown box, multiple select box and listbox. - Hidden value example
<form:hidden /> tags, render a HTML hidden value field. - Form errors tag example
<form:errors /> tag , render those form components error messages. - File upload example
File upload handling via Spring MultipartResolver.
7. Integrating Spring MVC with other frameworks
Integrate Spring MVC with others.

i don’t understand spring mvc flow and spring secruity please explain in simple ways
Hi, Where is 9?
Can you provide application event example. I wrote one :
@Component
public class AppStartListener implements ApplicationListener {
public void onApplicationEvent(ContextRefreshedEvent arg0) {
System.out.println(“Inside onApplication Listener”);
}
}
But this class is not running on application booting.
I want something like ServletContextListener in Spring 3.
How can I set context path for my Spring MVC web app?
Here’s what I’m wondering how to do, we have some existing Spring Web apps. There’s a request to have all the web apps map off the same base URL.
For example, let say the base URL needs to be ‘mtools’ and we have 2 web applications a dashboard and tracking.
The goal is to have the routes map like so ‘/mtools/dashboard’ and ‘/mtools/tracking’.
By default, the project POM specifies the ‘name’ and that name is the base context used by Servlet for Mapping/routing.
So I’m not sure how to override the context-base URL for the 2 web applications.
do you have any ideas?
thank you.
Thank you ! Mkyong

I am getting above error.
Address is one of the field in SchoolDetail class.
My SchoolDetail is an interface :
import java.util.Date;
public interface SchoolDetail {
public School getSchool();
public void setSchool(School School) ;
public String getDISENO() ;
public Address getAddress();
public void setAddress(Address addresses);
public long getId();

public void setIsNew(boolean isNew);
public boolean isNew();
}
It has got 2 implementations. BeanSchoolDetail and JpaSchoolDetail.
Address is again interface and has got 2 implementation similar to above
package gov.school.payroll.shared.model;
public interface Address{
public String getHouseNo();
public void setHouseNo(String houseNo);
public String getLine1();
public void setLine1(String line1);
public String getVillage();

which class is used to connect spring with mvc ?
Nice blog written on “Spring MVC” which described information on its flow, controllers, handlers, etc. The information contained in the blog is very helpful for Java developers. Here is an another informative blog published on Spring MVC & MongoDB http://findnerd.com/list/view/Spring-MVC-and-MongoDB/2240/ , hope this will help developers too to understand the Spring MVC in a detailed way. While learning from this blog developers can also post & view java questions and answers to enhance the tech knowledge among the developers community.

Hello Mkyong,
I really appreciate the way you describe the stuff.
I am very new to spring framework, I want to develop frames in spring and the frame in left side will interact with the frame at right side like “http://www.wicket-library.com/wicket-examples-6.0.x/frames/”, Could you please provide me some hint to achieve this. this may be pretty easy for you but as a newbie I am struggling to implement this. Hope you will help on this.
Hi Mkyong,

Spring MVC is expected to host N number of users at any ponit. What is the maximum N? What is the approach followed to attain such a number.
An interesting discussion is worth comment. I do believe that you ought to write more on this topic, it may not be a taboo matter but typically folks don’t discuss these issues. To the next! Cheers!!
Dear MkYong,
Please tell me how to overcome Browser back button issue in Spring MVC.?
Dear Priyanka,
That can be done by java script’s browser history option.
Hi Mkyong,
In your JSF 2 + Spring integration example, you didn’t use Spring MVC controller.
Is integrating Spring MVC with JSF 2 into a same web application not a good idea?
Will you please explain the reason?
Many Thanks.
Love the blog!
I was wondering if you’d have any sample code for extending abstract form class of spring, more specifically AbstractDataBoundFormElementTag.
I’d really like to learn how to write custom Spring Tags.
Anychance you have anything similar?
Cheers and keep up the good work!
Francis

plz give an example how to read data from excel/csv file in spring web mvc
plz reply soon
public class WidgetListExcelView extends AbstractExcelView
{
protected void buildExcelDocument(Map model,
HSSFWorkbook workbook,
HttpServletRequest request,
HttpServletResponse response)
{
…
}
}
AbstractExcelView implements the View’s render(Map model, HttpServletRequest request, HttpServletResponse response) for you, makes a new POI HSSFWorkbook, and makes you implement protected void buildExcelDocument(Map model, HSSFWorkbook workbook, HttpServletRequest request, HttpServletResponse response). From there, you can simply work on the workbook as you would in POI. Spring will handle the messy work of setting the response content type, streaming the workbook to the browser, etc. For more information on working with Excel documents via POI see Busy Developers’ Guide to HSSF Features at the official POI website.
Here is a full example to generate an Excel document of a list of Widgets:
/**
* View to generate an Excel document of a list of Widgets
* @author rlambert
*/
public class WidgetListExcelView extends AbstractExcelView
{
public static final String WIDGET_LIST_KEY = “widgetList”;
protected static final short WIDGET_NAME_COLUMN = 0;
protected static final short WIDGET_SIZE_COLUMN = 1;
protected void buildExcelDocument(Map model,
HSSFWorkbook workbook,
HttpServletRequest request,
HttpServletResponse response)
{
//CREATE THE SHEET
HSSFSheet sheet = workbook.createSheet(“Widget List”);
sheet.setDefaultColumnWidth((short) 12);
//GETCELL: getCell(SHEET, ROW, COLUMN);
short currentRow = 0;
//WRITE ROW FOR HEADER
HSSFCell header0 = getCell(sheet,
currentRow,
WIDGET_NAME_COLUMN);
setText(header0, “NAME”);
HSSFCell header1 = getCell(sheet,
currentRow,
WIDGET_SIZE_COLUMN);
setText(header1, “SIZE”);
List widgetList = (List) model.get(WIDGET_LIST_KEY);
Iterator widgetListIterator = widgetList.iterator();
while (widgetListIterator.hasNext())
{
currentRow++;
Widget widget = (Widget) widgetListIterator.next();
HSSFRow row = sheet.createRow(currentRow);
row.createCell(WIDGET_NAME_COLUMN)
.setCellValue(widget.getName());
row.createCell(WIDGET_SIZE_COLUMN)
.setCellValue(widget.getSize());
}
}
}
Here’s a simple Controller that uses the above WidgetListExcelView as the View:
package com.zabada.springbook.excel;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import com.zabada.springbook.dao.WidgetDAO;
/**
* Controller to show a Widget List in an Excel document
*
* @author rlambert
*/
public class WidgetListExcelController implements Controller
{
private WidgetDAO dao;
public void setWidgetDAO(WidgetDAO dao)
{
this.dao = dao;
}
/* (non-Javadoc)
* @see org.springframework.web.servlet.mvc.Controller
* #handleRequest(javax.servlet.http.HttpServletRequest,
* javax.servlet.http.HttpServletResponse)
*/
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1)
throws Exception
{
Map model = new HashMap();
List list = dao.getWidgets();
model.put(WidgetListExcelView.WIDGET_LIST_KEY, list);
return new ModelAndView(new WidgetListExcelView(), model);
}
}

Thanks for all your helpful post.
Do you have anything on spring mvc (CRUD) where there is a link to edit data on table using jquery dialog? am having problems passing the data to the dialog. Please help. Thanks in advance.
I love all your tutorials and I can’t wait until I get to read your MVC spring tutorial. Thanks a lot, your my teacher.
Thanks Mykong. It’s a very good site to understand emerging technologies. Will be very helpful if you can put some info on Spring’s Transaction Management and Spring Webflow. That will be great. Thanks a lot!
Great tutorial! Spring MVC is my favorite Java web framework. It’s easy to learn, very flexible, and it works! I strongly believe that the request/response paradigm is the way to go!
Thanks MkYong, good collection very useful.
MKyong, thank a lot for your SPRING MVC tutorial.
Ivo.
Could you show us how to handle the request for “WelcomePage” in @Controller class with @RequestMapping. For me it’ll be very helpful.
Hi mkyong,
Good to share knowledge related to java and frameworks. Really like it very much. 🙂 I hope you can post some tutorials about spring-mvc without using maven.
Thanks for your kind words. Maven is just a build tool, no dependencies AT ALL, you can just unplug it and still continue using Spring MVC.
hey ,Mk Yong i was just luking for the Spring 3.0 and hibernate integeration please guide with the demo how it is done…. i am trying it out but it is throwing certain exceptions

Hi MKYong,
may i know how to convert below project to Spring 2 ?
http://krams915.blogspot.com/2010/12/jqgrid-and-spring-3-mvc-integration.html
Thanks.
don’t know how to convert @ResponseBody Spring 3 to Spring 2..
Should i learn spring 3 or spring 2 ?

Depends on company, you should learn Spring DI concept, not the version.

Thank you a lot, your tutorials are awsome. So easy to learn from them.
This is very useful for freshers for better and easily understanding
MKYong,
You have an excellent ability to breakdown a complicated and overwhelming subject into a simple and easy-to-understand sections. For past year, I have been going through number of Spring Framework books where most authors talk and talk like politicians and never come down to a level of beginner developer and explain with some simple examples. I was never able to get a good grasp of how all the moving pieces work together until I luckily hit your website. Thankyou so much for your simple and clear examples. I was also impressed with your reply to one of the reader that you are also in the process of learning. That also speaks a lot about your good attitude that is often missing in today’s professional world ! Thanks again.
