In your custom deserializer, you can throw your own deserialization exception which extends JsonProcessingException. In your ControllerAdvice you can handle the HttpMessageNotReadableException and get the cause of this which is your custom exception. This way, you can throw the http code you want. ...

然后,通过throw关键字抛出一个CustomError实例,传入自定义的错误信息和错误码。 处理异常 在代码中使用throw抛出异常后,我们需要在上层代码中捕获并处理异常,否则程序会终止执行。通常使用try…catch语句来捕获异常,如下所示: try{ //可能发生异常的代码 thrownewError('发生了一个错误'); }catch(error) { //处理...
); } } catch (MyCustomException ex) { // 捕获自定义异常并处理 Console.WriteLine("捕获到自定义异常: " + ex.Message); } 希望以上解答能够帮助你更好地理解C#中的异常处理机制。
