作为升级Spring Jar的一部分，我们将Spring依赖项从2.5升级到4.3.0版本。 还将apache骆驼罐从1.6.0版本更新到了2.6.0（camel-core，camel-jms，camel-spring）
在春季升级之前，配置工作正常，如果提供的信息不清楚，请告知我。
下面是我们项目中使用的当前依赖项。
春季4.3.0， camel-core-2.6.0， camel-jms-2.6.0， 骆驼泉2.6.0， activemq-console-5.3.0.3a， activemq-core-5.3.0.3a， activemq-pool-5.3.0.3a， kahadb-fuse-5.3.0.3a， activemq-camel-fuse-5.3.0.3a
骆驼上下文配置如下：

DynamicEmbeddedRouter.java
import java.util.UUID;
import org.apache.camel.Exchange;
import org.apache.camel.Header;
import org.apache.camel.Message;
import org.apache.camel.RecipientList;
public class DynamicEmbeddedRouter
{
private String endpoint;
public DynamicEmbeddedRouter(String endpointName)
{
endpoint = (endpointName + ":");
}
@RecipientList
public String routeMessage(@Header(name="JMSCorrelationID") String destName, Exchange exchange) {
String destination = endpoint + destName;
exchange.getIn().setHeader("JMSCorrelationID", UUID.randomUUID().toString());
return destination;
}
}
以下是我们在升级jar之后看到的错误：
