WebService接口调试，xfire+spring2.0整合出现异常[java.lang.IllegalStateException: Could not find valid implementation for: 2.0]
使用Tomcat、Spring2.0、Xfire调试WebService接口，初始化Spring对象抛出以下异常：Error initializing XFireServlet.
1、日志显示：
[org.codehaus.xfire.transport.http.XFireServlet]-[ERROR] Error initializing XFireServlet. java.lang.IllegalStateException: Could not find valid implementation for: 2.0 at org.apache.xbean.spring.context.impl.XBeanHelper.createBeanDefinitionReader(XBeanHelper.java:48) at org.codehaus.xfire.spring.XFireConfigLoader.getXFireApplicationContext(XFireConfigLoader.java:74) at org.codehaus.xfire.spring.XFireConfigLoader.loadContext(XFireConfigLoader.java:41) at org.codehaus.xfire.transport.http.XFireConfigurableServlet.loadConfig(XFireConfigurableServlet.java:86) at org.codehaus.xfire.transport.http.XFireConfigurableServlet.createXFire(XFireConfigurableServlet.java:54) at org.codehaus.xfire.transport.http.XFireServlet.init(XFireServlet.java:45) at javax.servlet.GenericServlet.init(GenericServlet.java:212) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1173) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:809) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:129) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:859) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489)
2、分析及解决方法：
2.1、问题的原因是因为xfire不支持spring2.0的新特性，需要修改service.xml（\Tomcat\webapps\<项目目录>\WEB-INF\META-INF\xfire\service.xml）文件，将beans元素的命名空间放到services元素上:
修改前的xml如下：
<beans xmlns="http://xfire.codehaus.org/config/1.0"> <service> ...... </service> </beans> 修改后的xml如下： <beans> <services xmlns="http://xfire.codehaus.org/config/1.0"> ...... </services> </beans>
2.2、Spring包版本冲突，WebService Capailities（使用xfire）自带了Spring1.2.6的包，造成了和Tomcat的2.0版本的冲突：
删除Tomcat/Webapps/<项目目录>/WEB-INF/lib目录下的Spring1.2.6包
启动Tomcat
问题解决。
3、其他说明：
如果只执行了2.2的操作删除了jar包，而没有做2.1的修改，会出现以下错误（出现以下错误时，检查service.xml文件）：
