Spring MVC: Controller RequestMapping working, but return always gives a 404
I have a couple of SYSOUTs in my controller's methods, and they appear in the console log... verifying for me that all of the @RequestMapping is behaving as expected. The @Autowiring of an environment bean is also working (is also correctly displayed by a SYSOUT).
However, the methods' returns (I am using methods that return String type) are only resulting in 404s. The *.jsps aren't found. Project is using Maven; IDE is eclipse kepler, FWIW.
My ViewResolver is bog-standard. Can't see the disconnect.

My Controller:
package com.corpabc.bluprint.controllers;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import corpabc.xjp.configuration.env.Environment;
/**
*
* Handles requests for the application.
*/
@Controller
@RequestMapping("/*")
public class BluPrintController {
@Autowired
private Environment xjpEnvironment;
@RequestMapping("/init")
protected String catchInit(Map<String, Object> model) {
System.out.println("Got into init method. XJP Environment: "+xjpEnvironment);
model.put("xjp", this.xjpEnvironment);
return "envtest";
}
@RequestMapping("/*")
protected String catchAllOthers(Map<String, Object> model) {
System.out.println("Got into catch-all method: ");
return "defaultPage";
}
}
My envtest.jsp
is under /WEB-INF/jsp/
... but entering URL ~localhost:8080/bluprint/init
... I get a 404.
My defaultPage.jsp
doesn't exist... I would expect a not found condition here, and that's what I get when I enter ~localhost:8080/bluprint/
. Not sure if it should be a 404, specifically, but that's what I get, in any case.
I suspect that you problem is in your servlet mapping. /* will force everything through your dispatcher servlet, including jsps. Try losing the *. I'll find the relevant part in the servlet spec and update....
From the servlet spec:
12.2 Specification of Mappings In the Web application deployment descriptor, the following syntax is used to define mappings: A string beginning with a '/' character and ending with a '/*' suffix is used for path mapping.
A string beginning with a '*.' prefix is used as an extension mapping.
The empty string ("") is a special URL pattern that exactly maps to the application's context root, ie, requests of the form . In this case the path info is '/' and the servlet path and context path is empty string (““).
A string containing only the '/' character indicates the "default" servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.
All other strings are used for exact matches only.
So if you specify /* that overrides the *.jsp mapping, so jsp requests get routed back into your dispatcher servlet instead of hitting the jsp.
