Camel recipientListにClassCastExceptionがあります

Question

私はApache Camelを使用して、プログラムの実行時に動的に宛先を指定しようとしています。 recipientListパラメータをList of Endpointに変更すると、ClassCastExceptionが発生します。

私は何かを逃した場合アドバイスに役立つことができる誰か？

ありがとうございます。 - > "

Answer 1

あなたはRECIPIENTLISTヘッダに

List<Endpoint> 

を置くが、ドキュメント（http://camel.apache.org/recipient-list.html、 "動的受信者リスト" によるとされている次のよう

from("jms:queue:jms/XXXQ").recipientList(header("recipientList")); 

List<Endpoint> eps = new ArrayList<Endpoint>(); 
CxfEndpoint endpoint = exchange.getContext().getEndpoint("cxf:bean:configServiceEndpoint", CxfEndpoint.class); 

endpoint.setAddress(URL); 
endpoint.setWsdlURL(WSDL); 
eps.add(endpoint); 

CxfProducer cp = (CxfProducer) endpoint.createProducer(); 
cp.start(); 

exchange.getIn().setHeader("recipientList", eps); 

<cxf:cxfEndpoint id="configServiceEndpoint" address="${CXFTestSupport.URL}" wsdlURL="${CXFTestSupport.WSDL}" serviceClass="com.company.client.ClientService"> 
</cxf:cxfEndpoint> 

例外反復可能な値 "）エンドポイントオブジェクトは使用できません。

反復可能なようでなければならないヘッダで定義されている受信者の動的リスト：

• のjava.util.Collection
• するjava.util.Iterator
• アレイ
• org.w3c。 dom.NodeList
• 任意の他のタイプは、単一の値とみなされる
• カンマで区切られた値を持つ単一のString
