@RestControllerAdvice
    @Slf4j
    public class FinanceExceptionAdvice {
        @ResponseBody
        @ExceptionHandler(Exception.class)
        public Result exceptionHandler(Exception e) {
            log.error("执行异常", e);
            if (e instanceof MethodArgumentNotValidException) {
                MethodArgumentNotValidException exception = (MethodArgumentNotValidException) e;
                return Result.getBusinessException(exception.getMessage(), ResponseStatus.BUSINESS_ERROR_STATUS.getCode());
            } else if (e instanceof OrderException) {
                OrderException exception = (OrderException) e;
                return Result.getBusinessException(exception.getMessage(), ResponseStatus.BUSINESS_ERROR_STATUS.getCode());
            } else {
                return Result.getBusinessException("后台异常，请联系管理员！", ResponseStatus.BUSINESS_ERROR_STATUS.getCode());
            }
        }
    }

其中OrderException是根据业务自定义的异常

import java.io.Serializable;
    
    public class OrderException extends RuntimeException implements Serializable {
        private static final long serialVersionUID = 6037840863824232187L;
        private String code;
    
        public OrderException() {
        }
    
        public OrderException(String message, Throwable cause) {
            super(message, cause);
        }
    
        public OrderException(String message) {
            super(message);
        }
    
        public OrderException(Throwable cause) {
            super(cause);
        }
    
        public OrderException(String message, String code) {
            super(message);
            this.code = code;
        }
    
        public OrderException(String message, String code, Throwable cause) {
            super(message, cause);
            this.code = code;
        }
    
        public String getCode() {
            return this.code;
        }
    }
