Question

Camel配置在V2.13.4上运行良好。迁移到v2.15.1之后，我得到以下错误：

Caused by: org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.apache.camel.component.cxf.spring.NamespaceHandler] for namespace [http://camel.apache.org/schema/cxf]: problem with handler class file or dependent class; nested exception is java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=org/apache/camel/component/cxf/spring/NamespaceHandler, offset=6

在camel配置中，我使用以下模式：

    <beans xmlns="http://www.springframework.org/schema/beans"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:cxf="http://camel.apache.org/schema/cxf"
            xsi:schemaLocation="
               http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
               http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd
               http://camel.apache.org/schema/cxf http://camel.apache.org/schema/cxf/camel-cxf.xsd">

            address="/data" endpointName="s:dataManagementSOAP"
            serviceName="s:dataManagement"

您似乎正在Java6.0上运行您的应用程序，Apache有自2.14.0以来对Java6.0的不再支持 (请参阅“升级时要考虑的重要更改”一节)

在Java6.0中重新编译camel是不可行的，我相信您的选择要么升级到Java7.0，要么将Camel降级为2.14.0版
