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;
}

有任何提示要纠正这个问题吗？
