问题描述
如题.springMVC+CXF3.0,部署到tomcat下启动,一切ok.用脚本启动一直报错NoClassDefFoundError:Couldnotinitializeclasscom.sun.xml.bind.v2.model.impl.RuntimeModelBuilder.网上查说是jdk版本的问题,但我的已经是1.6.24,应该不存在说的问题.看了一下,报错的这个类在jdk的rt.jar和jaxb-impl-2.2.7.jar下面都有.怀疑是类加载顺序问题,在jre的endorsed下放了jaxb-impl-2.2.7.jar也是没用.请教大家,这个可能是什么问题导致.启动脚本代码:publicclassSpringUtilTest{publicstaticApplicationContextapplicationContext=newClassPathXmlApplicationContext("classpath:spring*.xml");publicstaticApplicationContextgetApplicationContext(){returnapplicationContext;}publicstaticvoidmain(String[]args){System.out.println("springinitfinlished...");System.out.println(System.getProperty("java.endorsed.dirs"));System.out.println(System.getProperty("java.ext.dirs"));AccessCANcan=(AccessCAN)getApplicationContext().getBean("accessCAN");//BaseDaodao=(BaseDao)getApplicationContext().getBean("baseDao");////TransactionDaotdao=(TransactionDao)getApplicationContext().getBean("transactionDao");try{//System.out.println(JSON.toJSONString(dao.queryForList("selectinvnoasinvNofromBTAS_Transactionwhere1=1")));//System.out.println(JSON.toJSONString(tdao.getInvnosByTimestamp("","")));//can.orderupload(null);}catch(Exceptione){e.printStackTrace();}System.out.println("over");}}
CXF配置主要就是这句:<jaxws:endpointid="IurPoServices"implementor="jeecg.citsamex.hoteliur.ws.impl.IurPoServicesImpl"address="/IurPoServices"/>

解决方案
解决方案二：
看上去还是版本问题，看看是不是第三方包里有了那个包，却没那个类
解决方案三：
java.lang.NoClassDefFoundError这个异常代表着jar包不存在或者冲突
解决方案四：

第三方就只有tomcat了,我看了tomcat下的jar包,没有哪个包里有这个类的,工程引用的就前边提到的两个jar包里有这个类.

jar包肯定是存在的,因为部署到tomcat下是可以启动的.现在看就是有两个jar包都有这个类,所以猜测是引用错了,但这两个jar包感觉都不能删里面的类的,有什么方式可以设置先加载哪个类吗,我试着在jre下的设置好像是没有作用的.
