I just started learning spring mvc. Trying to follow a hello world sample.
Everything seems to be working fine, except the jsp view is not able to receive the model attribute value set in the controller.
Here's some code.
Controller:
package org.home.webapp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
#Controller
#RequestMapping("/welcome")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
}
View
<%# page language="java" contentType="text/html; charset=ISO-8859-1"

Using <%# page isELIgnored="false" %> helped.
We need to include org.springframework.web.servlet.ModelAndView instead of org.springframework.web.portlet.ModelAndView;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
#Controller
public class HelloWorldController {
#RequestMapping("/hello")
public ModelAndView hello()
{
System.out.println("Just Test iNside");
String message = "HELLO SPRING MVC HOW R U";
return new ModelAndView("hello", "message", message);
}
Using follwing code my issue resolved, may be its helpfull for you

Try this changes may be it will work for you
you can use <th:block th:text="${your_attribut_name}"/>
example controller
#RequestMapping(method = RequestMethod.GET)
public String printWelcome(ModelMap model) {
model.addAttribute("message", "Spring 3 MVC Hello World");
return "hello";
}
view
<h1>Message : <th:block th:text="${message}"/></h1>
output
Message : Spring 3 MVC Hello World

Something wrong with you context path. According to form you submitting, try this:
<FORM ACTION="${pageContext.request.contextPath}/validate">
Compare this two urls :
http://localhost:9080/LaunchingGateway_Maintance/services/Test
and
http://localhost:9080/validate
So looks like you are missing some context path LaunchingGateway_Maintance

The output which I am getting is
Print: world
The ${message} is not getting printed
Someone please help me with this
Thanks in advance
The message attribute is added to the MODEL in the printHello method:
#Controller
#RequestMapping("/hello")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model)
{
model.addAttribute("message", "Hello");
return "index";
}
}
which will get executed when you make a GET request for /hello (http://host:port/appContext/hello). But you have the below entry in web.xml file:
<welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>
and the web container will use this file for appending to a request for / to show index.jsp to the user, as you don't have any handler method mapped to / URL. So, in order to show the message to the user, remove the <welcome-file-list> entry from web.xml and change HelloController to this:
#Controller
#RequestMapping("/")
public class HelloController {
#RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model)
{
model.addAttribute("message", "Hello");
return "index";
}
}
Get rid of
<welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>
And make your request to
http://yourhost:yourport/YourApp/hello
to match your #Controller mapping.
If you make your request to
http://yourhost:yourport/YourApp
and any of the <welcome-file> entries exist, those will be chosen before your Servlet is hit.
