如何在Spring Boot的JSON响应中显示异常名称

import org.springframework.boot.web.servlet.error.ErrorController;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/error")
public class CustomErrorController implements ErrorController {

    @RequestMapping
    public ResponseEntity<ErrorResponse> handleError(HttpServletRequest request) {
        // 获取异常信息
        Object status = request.getAttribute(RequestDispatcher.ERROR_STATUS_CODE);
        Object error = request.getAttribute(RequestDispatcher.ERROR_EXCEPTION);

        // 构建自定义的错误响应
        ErrorResponse response = new ErrorResponse();
        response.setStatus((Integer) status);
        response.setError(error.getClass().getSimpleName()); // 获取异常名称

        return new ResponseEntity<>(response, HttpStatus.INTERNAL_SERVER_ERROR);
    }

    @Override
    public String getErrorPath() {
        return "/error";
    }
}

public class ErrorResponse {
    private int status;
    private String error;

    // 省略 getter 和 setter 方法
}

server.error.whitelabel.enabled=false

server:
  error:
    whitelabel:
      enabled: false
