请求BODY在Apache-Camel上的Exchange期间返回NULL

Question

我有一个使用Apache-camel（版本2.9.1）的项目来检索一些信息。问题是当我调用方法时：

 final DecriptResponseHSMConnector responseData = camelTemplate
.requestBodyAndHeaders(CXFRS_BEAN_HSM_CONNECTOR_CLIENT,
  cardDataRequest, param,
  DecriptResponseHSMConnector.class); 

请求Body和Headers我得到例外：

Exception in thread "main" org.apache.camel.CamelExecutionException: Exception occurred during execution on the exchange: Exchange[Message: DecriptCardDataRequest [dataType=SOMEDATA, bdk=SOMEDATA, keySerialNumber=SOMEDATA, encryptedData=SOMEDATA]]

NullPointerException 的确切点在于 ExchangeHelper.class类（来自apache-camel的内部类）的以下方法，此处：

public static Object extractResultBody(Exchange exchange, ExchangePattern pattern) {
    Object answer = null;
    if (exchange != null) {
        // rethrow if there was an exception during execution
        if (exchange.getException() != null) {
            throw ObjectHelper.wrapCamelExecutionException(exchange, exchange.getException());
        }

        // result could have a fault message
        if (hasFaultMessage(exchange)) {
            return exchange.getOut().getBody();
        }

        // okay no fault then return the response according to the pattern
        // try to honor pattern if provided
        boolean notOut = pattern != null && !pattern.isOutCapable();
        boolean hasOut = exchange.hasOut();
        if (hasOut && !notOut) {
            // we have a response in out and the pattern is out capable
            answer = exchange.getOut().getBody();
        } else if (!hasOut && exchange.getPattern() == ExchangePattern.InOptionalOut) {
            // special case where the result is InOptionalOut and with no OUT response
            // so we should return null to indicate this fact
            answer = null;
        } else {
            // use IN as the response
            answer = exchange.getIn().getBody();
        }
    }
    return answer;
}
