解决spring boot无法捕捉404异常问题

@ExceptionHandler(NoHandlerFoundException.class)
    @ResponseStatus(value = HttpStatus.NOT_FOUND)
    @ResponseBody
    public ResponseEntity<ErrorResponse> handle404(NoHandlerFoundException e) {

        LOGGER.info("Resource Not found, RequestURL: {}, HttpMethod: {}, Headers: {}", e.getRequestURL(),
                e.getHttpMethod(), e.getHeaders());
        LOGGER.error(e.getMessage(), e);
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON_UTF8);

        return new ResponseEntity<>(new ErrorResponse(WebExceptionCode.NOT_FOUND), headers, HttpStatus.NOT_FOUND);
    }

#出现错误时, 直接抛出异常
spring.mvc.throw-exception-if-no-handler-found=true
#不要为我们工程中的资源文件建立映射
spring.resources.add-mappings=false
