spring mvc Always JSON repsonse - spring-mvc

Question

I'm trying to learn Spring MVC and i'm stuck at this program behaving weirdly can any one please help.
#Controller
public class GreetingController {
#RequestMapping(value="/greeting", consumes={"application/json", "application/xml"},produces = {"application/json","application/xml"}, headers = "Content-type=*/*")
public #ResponseBody Greeting greeting(
#RequestParam(value="name", required=false, defaultValue="I'm default") String name) {
Greeting obj = new Greeting("1",name);
Address address = new Address("CA, US");
obj.setAddress(address);
return obj;
}
}
Greeting and Address are just POJO's.
here is the output from 'curl' i.e irrespective of Content-type output is in JSON format.
curl --header "Content-type: application/xml" http://host.com:8080/javamvc/greeting
{"id":1,"content":"Hello, I'm default!","address":{"addr":"CA, US"}}
curl --header "Content-type: application/json" http://host.com:8080/javamvc/greeting
{"id":1,"content":"Hello, I'm default!","address":{"addr":"CA, US"}}
and then when i use 'RestClient' from mozilla i get output as xml always as irrespective of my Content-type=application/json or Content-type=application/xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><greeting><id>1</id><content>Hello, I'm default!</content><address><addr>CA, US</addr></address></greeting>
Can anyone please help?

Answer 1

In your curl requests, you are specifying the Content-Type of the request body, not the content type you are expecting in the response body.
For that, you need to specify the Accept header.
Spring is always producing application/json, because it's the first in the list of produces values.
You'll have to be more specific about what you are doing with Mozilla, but it seems like it's requesting with the Accept header being application/xml.
