我有一个SpringBoot控制器，并且我想为Exceptions返回正确的http代码状态。因此，我的问题是：哪种HTTP状态代码更适合Exception，那么“
500”或“ 409”哪个更好？

这是我的代码：

@PostMapping(value = {"", "/"})
public ResponseEntity<Response> create(@RequestBody StudioDto studioDto,
        ServletRequest servletRequest, ServletResponse servletResponse) {

    Response response = new Response();

    try {
        studioService.createStudio(studioDto);
        response.setMessage("The studio was create");
        response.setStatusCode(HttpServletResponse.SC_CREATED);

    } catch (Exception e) {
        response.setMessage("Op we have a little problem");
        response.setErrorMessage(e.getMessage());

        //Which one
        //this one 5xx
        response.setStatusCode(500);
        //Or this one 4xx
        response.setStatusCode(409);
    }

    return new ResponseEntity(response, response.getHttpStatus());
}
