I create a virtual route to explain my purpose but indeed the error is not
at all related to what I copy.
Here is the route corresponding to what I have
*Scenario 1 : @Hanlder added to both methods*
<!--
Core component Flow IN to OUT Process P3 technical parsing
-->
<camel:route errorHandlerRef="txErrorHandler">
<camel:from ref="queueRequestEndpoint" />
<camel:transacted ref="PROPAGATION_REQUIRED" />
<camel:doTry>
<camel:convertBodyTo
type="com.xpectis.x3s.platform.model.Request" />
<!-- Parse the request -->
<camel:bean ref="serviceHelper" method="parseRequest" />
<!-- Update request status -->
* <camel:bean ref="serviceHelper"
method="updateRequestStatus"/>*
<!-- Put request in the queue -->
<camel:to ref="directRequestMessageEndpoint" />
<camel:doCatch>
<camel:exception>com.xpectis.x3s.exception.X3SClientException</camel:exception>
<camel:bean ref="serviceHelper"
method="processException" />
<camel:to ref="queueReportingEndpoint" />
</camel:doCatch>
<camel:doCatch>
<camel:exception>java.lang.Exception</camel:exception>
<camel:to
uri="log:x3slog?level=DEBUG&multiline=true" />
<camel:rollback/>
</camel:doCatch>
</camel:doTry>
</camel:route>
<!--
Core component Flow IN to OUT Process P3 request message
creation
-->
<camel:route errorHandlerRef="txErrorHandler">
<camel:from ref="directRequestMessageEndpoint" />
<camel:transacted ref="PROPAGATION_REQUIRED" />
<camel:doTry>
<!-- Split the collection of messages -->
<camel:split strategyRef="aggregationStrat">
<camel:ognl>request.body</camel:ognl>
<!-- (1) Call the service to save the request message -->
<camel:bean ref="serviceHelper"
method="createRequestMessage" />
<!-- (2) Validate the business message -->
<camel:bean ref="serviceHelper"
method="validateRequestMessage" />
<!-- (3) Save business message -->
<camel:bean ref="serviceHelper" method="saveRequestMessage"
/>
</camel:split>
<!-- Update Request status -->
* <camel:bean ref="serviceHelper" method="updateRequestStatus" />
*
<!-- <camel:bean ref="serviceHelper" method="generateError" />
-->
<!-- Put result in queue -->
<camel:to ref="queueRequestMessageEndpoint" />
<camel:doCatch>
<camel:exception>java.lang.Exception</camel:exception>
<camel:to
uri="log:x3slog?level=DEBUG&multiline=true" />
<camel:rollback/>
</camel:doCatch>
</camel:doTry>
</camel:route>
and the methods :
@Handler
public void updateRequestStatus(
@Header(value = "messageType") String messageType,
@Header(value = "requestStatus") String requestStatus,
@Header(value = "requestId") String requestId,
Exchange exchange) {
@Handler
public List<RequestMessage> updateRequestStatus(
@Header(value = "messageType") String messageType,
@Header(value = "requestId") String requestId,
@Body List<RequestMessage> requestMessages) {
error :
Exception: org.apache.camel.component.bean.AmbiguousMethodCallException:
Ambiguous method invocations possible: [public java.util.List
com.xpectis.x3s.core.util.ServiceHelper.updateRequestStatus(java.lang.String,java.lang.String,java.util.List),
public void
com.xpectis.x3s.core.util.ServiceHelper.updateRequestStatus(java.lang.String,java.lang.String,java.lang.String,org.apache.camel.Exchange)]
*Scenario 2 : @Hanlder added to method with void
*In this case, I don't have any error returned Exception:
org.apache.camel.component.bean.AmbiguousMethodCallException BUT the method
without the @Handler annotation is executed and not the other.*
