How to set respond header values in Spring Boot rest service method?

Question

Newbie question... I\'m building my first Spring Boot restful service. My restful service design requires some data to be returned in the response header.

How do I

Answer 1

I was looking for an answer, and I don't like to have to create a response entity. I found the solution on the spring-forums, so credits to the writer.

In short, you can request the response in the method-declaration, so this can be populated.

A simple example:

@RequestMapping(value="/car/{carId}", method = RequestMethod.Get)
@ResponseBody
public Car getCarById(@PathVariable("carId") String Id, HttpServletResponse response) {

    response.setHeader("X-Special-Header", myCar.getEcoLabel());
    //get the car
    return myCar;
}

Hope this helps others as well.
