Return only string message from Spring MVC 3 Controller

My spring controller has a endpoint where I want to only:

1. set the http response code
2. return a string back, don't need to render a .jsp view page or anything.

So will want to set the http status code to 200 OK or 500 etc.
And simply return a string like “OK”.

How can I do this, or am I forced to render a .jsp view page?

Use the @ResponseBody annotation:

@RequestMapping(value="/sayHello", method=GET)
@ResponseBody
public String whatever() {
    return "Hello";
}

See the @ResponseBody ref docs for further details.

You may be able to use the @ResponseStatus annotation to set the code rather than using the HttpServletResponse directly.
