我有一个标有//in loop
<td class="col-md-2" align="right">
<div class="btn-group pull-left">
<input id="@item.CustomerID" name="getCustomerID" class="customerCheck" type="checkbox" value="@item.CustomerID" autocomplete="off" />
</div>
</td>
//click on checkbox (any)
$('.customerCheck').click(function () {
//see all the checked checkboxs and loop through them
$('input[type=checkbox]:checked').each(function () {
//get their id and make it a comma separated string
var sSheckID = $('input[type=checkbox]:checked').map(function () {
return $(this).attr('id');
}).get().join();
//set is as the value of the output box.
$("#CustomerID").val(sSheckID);
$("#CustomerID").attr('value', sSheckID);
});
});
//output
<input class="form-control" id="customerID" name="MCustomerID" type="text"/>
的Kafka侦听器：
@Controller而且，我有一个标记为@KafkaListener(topics = "${binlookup.kafka.topic.insert}")
public BinInfoJsonDTO listenAndInsert(String binInfoJson, Acknowledgment ack) {
log.debug("Kafka server: {}", bootstrapServers);
log.info("Kafka inserting: {}", binInfoJson);
ObjectMapper mapper = new ObjectMapper();
BinInfoJsonDTO dto;
BinLookupError error;
String responseError;
try {
dto = mapper.readValue(binInfoJson, BinInfoJsonDTO.class); // <--- exception happens here
log.debug("The converted DTO: {}", dto);
ResponseEntity<BinInfoJsonDTO> response = controller.insertBIN(Utilities.jsonDtoToEntity(dto));
log.debug("BIN inserted by Kafka. {}", response);
if (response.getStatusCodeValue() == HttpStatus.OK.value() ||
response.getStatusCodeValue() == HttpStatus.CREATED.value()) {
ack.acknowledge(); // manual acknowledge.
log.debug("Acknowledged.");
} else {
responseError = "Unexpected response status code: " + response.getStatusCodeValue();
log.error(responseError);
error = new BinLookupError(responseError);
error.setErrorType(ErrorTypeEnum.UNEXPECTED_STATUS_CODE);
throw new BinLookupException(error);
}
} catch (JsonProcessingException e) {
log.error("Cannot parse Kafka incoming JSON. ", e);
error = new BinLookupError(e.getMessage());
error.setErrorType(ErrorTypeEnum.KAFKA_JSON_FAILURE);
throw new BinLookupException(error);
} catch (IOException e1) {
log.error("I/O exception in Kafka. ", e1);
error = new BinLookupError(e1.getMessage());
error.setErrorType(ErrorTypeEnum.IO_EXCEPTION);
throw new BinLookupException(error);
}
return dto;
}
的异常处理程序：
@ControllerAdvice现在，当我运行应用程序并将错误格式的JSON输入生产者时，将发生异常，但异常处理程序无法捕获该异常。 @Slf4j
@ControllerAdvice
public class BinLookupExceptionHandler extends ResponseEntityExceptionHandler {
@ExceptionHandler(value = {BinLookupException.class})
protected ResponseEntity<BinLookupError> handleBinLookupException(BinLookupException ex) {
BinLookupError error = ex.getError();
log.error("Exception handler: {}", error.getOriginalMsg());
...
}
是例外。

不存在。
我还应该做些什么才能使其意识到我抛出的异常？谢谢。
