没有@ EnableWebMvc，NoHandlerFoundException的自定义异常处理程序将无法工作

问题描述

我想覆盖404错误的html错误页面作为JSON响应.当我在没有 @EnableWebMvc 的情况下使用 @ControllerAdvice 时，它将无法正常工作.

I want to override html error page for 404 responses as an JSON response. When i use @ControllerAdvice without @EnableWebMvc it is not working.

@EnableWebMvc   // if i remove this, it is not working
@ControllerAdvice
@Order(Ordered.HIGHEST_PRECEDENCE)
public class GlobalControllerExceptionHandler {

    @ExceptionHandler(NoHandlerFoundException.class)
    public ResponseEntity<ZeusErrorDTO> noHandlerFoundException(
                    HttpServletRequest request,
                    NoHandlerFoundException exception) {

        ErrorDTO errorDTO = new ErrorDTO();
        return new ResponseEntity<>(errorDTO, HttpStatus.NOT_FOUND);
    }
}

有没有 @EnableWebMvc 的自定义异常处理选项，因为它会覆盖在application.yml中声明的Spring配置.

Is there an option for custom exception handling without @EnableWebMvc, because it overrides Spring configurations which are declared inside application.yml.

推荐答案

我通过在application.yml中添加配置之一轻松解决了问题.

I easily resolved problem by adding one of configurations in application.yml.

spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false

或

spring.mvc.throw-exception-if-no-handler-found=true
spring.mvc.static-path-pattern: /static

如果您不限制Spring并且没有处理程序与您的请求匹配，则spring会尝试查找静态内容.

If you don't restrict Spring and no handler matches with your request, then spring tries to look for static content.
