ContentNegotiatingViewResolver

[John Eric Hamacher]

Hello:

I have a RESTful web service in which I want to give the client the option of receiving either XML or JSON by specifying the extension on the URL:

	@RequestMapping(value="/get/{district}/{wsn}", method=RequestMethod.GET, headers={"Accept=text/xml, application/json"})
	public @ResponseBody LookupResult lookup(@PathVariable String wsn, @PathVariable String district) {
		System.err.println("WWWWWW wsn= " + wsn + "  district = " + district);
		LookupResult lr = new LookupResult(true);
		return lr;
	}

<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"> <property name="mediaTypes"> <map> <entry key="xml" value="text/xml" /> <entry key="json" value="appplication/json"/> </map> </property> </bean>


If I send:

http://localhost::9081/SIMS_Student_Location_Confirm/SIMS/get/2828/1234567890.json

I only get only JSON back if I specify the Accept header as application/json. If I specify both text.xml and application/json in the header, I always get XML back, no matter what extension I use. I'd like the extension to determine the format of the output. I've been trying to follow the new Spring in Action book but there is something missing in the text.

Thanks
eric
