Web MVC JSON Setup fails or is incomplete
Hello,
I'm new to Spring, just bought the Book "Spring in Action" and got a basic overview about the Framework with DI and Aspects. I'm now digging further in to the book but appart from that I want to learn on a practical example. And I think doing it with Roo is the most convenient way to also learn the best practices.
I want to achieve a RESTful Web MVC Setup with MongoDB as backend. I'm using Spring Roo 1.2.3.RELEASE, Maven 3.0.4 and Java 1.6.0_37. I'm using a 64bit Mac OS X and the command line to achieve the tasks.
I have executed the following commands to create my roo project:
Code:
/ Spring Roo 1.2.3.RELEASE [rev 7fd62b6] log opened at 2012-12-30 19:04:59
hint
project --topLevelPackage com.eerra.cardkeeperweb
mongo setup
entity mongo --class ~.domain.Card --testAutomatically
field string --fieldName name --sizeMin 2 --notNull --class ~.domain.Card
field string --fieldName barcode --sizeMin 2 --notNull --class ~.domain.Card
json all
web mvc json setup
web mvc json all --package ~.controller
web mvc setup
web mvc all --package ~.controller
logging setup --level DEBUG
quit
// Spring Roo 1.2.3.RELEASE [rev 7fd62b6] log closed at 2012-12-30 19:12:44
Then I executed the Maven build and start of Jetty from the command line:
Code:
mvn clean package
mvn jetty:run-war
The Jetty Container is starting and I can reach the default page by opening the URL:
http://localhost/cardkeeperweb
But when I click on to the "Create New Card" link on the left hand side I get following message:
Requested Resource not found
In the DEBUG Log I see following entry:
RequestMappingHandlerMapping - Did not find handler method for [/cards]
So I guess the REST methods are still missing. Does anybody know how to add them?
Code:
The DEBUG log output is following:

This indicates that the resource has not been setup successfully. Indeed I don't seem to have GET, POST, PUT, DELETE functions anywhere in my controller or the associated aj files.
CardController_Roo_Controller.aj
Code:
package com.eerra.cardkeeperweb.controller;
import com.eerra.cardkeeperweb.controller.CardController;
import com.eerra.cardkeeperweb.domain.Card;
import java.io.UnsupportedEncodingException;
import javax.servlet.http.HttpServletRequest;
import org.springframework.ui.Model;
import org.springframework.web.util.UriUtils;
import org.springframework.web.util.WebUtils;
privileged aspect CardController_Roo_Controller {
void CardController.populateEditForm(Model uiModel, Card card) {
uiModel.addAttribute("card", card);
}
String CardController.encodeUrlPathSegment(String pathSegment, HttpServletRequest httpServletRequest) {
String enc = httpServletRequest.getCharacterEncoding();
if (enc == null) {
enc = WebUtils.DEFAULT_CHARACTER_ENCODING;
}
try {
pathSegment = UriUtils.encodePathSegment(pathSegment, enc);
} catch (UnsupportedEncodingException uee) {}
return pathSegment;
}
}
CardController.java
Code:
package com.eerra.cardkeeperweb.controller;
import com.eerra.cardkeeperweb.domain.Card;
import org.springframework.roo.addon.web.mvc.controller.json.RooWebJson;
import org.springframework.roo.addon.web.mvc.controller.scaffold.RooWebScaffold;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@RooWebJson(jsonObject = Card.class)
@Controller
@RequestMapping("/cards")
@RooWebScaffold(path = "cards", formBackingObject = Card.class)
public class CardController {
}
Can somebody tell me what I'm doing wrong or what's missing?
Thanks for your help,
Chris
