Spring Boot404错误自定义错误响应Rest

Answer 1

对于那些不想使用@enablewebmvc的Spring Boot2用户

应用程序.属性

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

控制器建议

@RestControllerAdvice
public class ExceptionResolver {

    @ExceptionHandler(NoHandlerFoundException.class)
    @ResponseStatus(HttpStatus.NOT_FOUND)
    public HashMap<String, String> handleNoHandlerFound(NoHandlerFoundException e, WebRequest request) {
        HashMap<String, String> response = new HashMap<>();
        response.put("status", "fail");
        response.put("message", e.getLocalizedMessage());
        return response;
    }
}
