I'm using Spring MVC 3.2 @RequestMapping and @ResponseBody as REST Service. A example endpoint looks like this:
@RequestMapping(value = "query", method = RequestMethod.GET)
@ResponseBody
public Locations searchHandler(@RequestParam String q, HttpServletRequest request, HttpServletResponse response) {
...
Sending a wrong request for non existing endpoints or missing GET parameter q will show the Tomcat 7 error report:
<html>

How can I disable this error page. I just want the error message as content without any HTML or further informations.

Ok I found the Solution. I implemented a Exception handler as described in the link above:
@ControllerAdvice
public class ErrorController {
/**
* .
* @param request .
* @param response .
* @throws Exception .
*/
@ExceptionHandler(Exception.class)
public void handleConflict(HttpServletRequest request, HttpServletResponse response, Exception e) throws Exception {
// If the exception is annotated with @ResponseStatus rethrow it and let
// the framework handle it - like the OrderNotFoundException example
// at the start of this post.
// AnnotationUtils is a Spring Framework utility class.
if (AnnotationUtils.findAnnotation(e.getClass(), ResponseStatus.class) != null) {
throw e;
}
response.setStatus(400);
response.getWriter().println(e.getMessage());
}
}
Its important to use response.getWriter()... instead of using response.sendError().
