Return simple text String with ModelAndView

How can I return a simple text String like below, basically I want to display a simple text for my error in the browser.

I handle my error in here and here I want to do it:

@ExceptionHandler(Exception.class)
public ModelAndView handleAllException(Exception e) {

}

The problem is I have to return a ModelAndView. How can I return a simple text to the browser, do not want to use any JSP etc.

Just return the same way like below or similar:

return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(e.getMessage());

For example this does not work:

return new ModelAndView((View) ResponseEntity.status(HttpStatus.BAD_REQUEST).body(e.getMessage()));

You could do:

public ModelAndView handleAllException(Exception e) {
    ModelAndView mav = new ModelAndView("your_jsp_name");
    modelAndView.addObject("name", "Peter");
    ...
    return mav;
}

From the @ExceptionHandler documentation:

Handler methods which are annotated with this annotation are allowed to have very flexible signatures. They may have parameters of the following types, in arbitrary order: [...] OutputStream / Writer for generating the response's content. This will be the raw OutputStream/Writer as exposed by the Servlet API. [...]

So you could define an exception handling method which looks something like this:

@ExceptionHandler(Exception.class)
public void handleAllException(Exception e, Writer responseWriter) {
  responseWriter.write(e.getMessage());
}

You can obviously do something more complex to format the error message, but that's the basic idea.
