給WebService注入其他類的時候，報空指標錯誤。

web.xml配置如下:

<servlet> <servlet-name>XFireServlet</servlet-name> <servlet-class>org.codehaus.xfire.transport.http.XFireConfigurableServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet>

結果當webservice呼叫webservice服務時，報錯：

org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException org.codehaus.xfire.fault.XFireFault: Fault: java.lang.NullPointerException at org.codehaus.xfire.fault.Soap11FaultSerializer.readMessage(Soap11FaultSerializer.java:31) at org.codehaus.xfire.fault.SoapFaultSerializer.readMessage(SoapFaultSerializer.java:28) at org.codehaus.xfire.soap.handler.ReadHeadersHandler.checkForFault(ReadHeadersHandler.java:111) at org.codehaus.xfire.soap.handler.ReadHeadersHandler.invoke(ReadHeadersHandler.java:67) at org.codehaus.xfire.handler.HandlerPipeline.invoke(HandlerPipeline.java:131) at org.codehaus.xfire.client.Client.onReceive(Client.java:406) at org.codehaus.xfire.transport.http.HttpChannel.sendViaClient(HttpChannel.java:139) at org.codehaus.xfire.transport.http.HttpChannel.send(HttpChannel.java:48) at org.codehaus.xfire.handler.OutMessageSender.invoke(OutMessageSender.java:26) at org.codehaus.xfire.handler.HandlerPipeline.invoke(HandlerPipeline.java:131) at org.codehaus.xfire.client.Invocation.invoke(Invocation.java:79) at org.codehaus.xfire.client.Invocation.invoke(Invocation.java:114) at org.codehaus.xfire.client.Client.invoke(Client.java:336) at org.codehaus.xfire.client.XFireProxy.handleRequest(XFireProxy.java:77) at org.codehaus.xfire.client.XFireProxy.invoke(XFireProxy.java:57) at $Proxy0.btsPower(Unknown Source) at com.boco.veh.ws.test.WSTest.main(WSTest.java:36)

這個問題可以通過如下配置解決。

<servlet> <servlet-name>XFireServlet</servlet-name> <!-- 不整合時使用org.codehaus.xfire.transport.http.XFireConfigurableServlet --> <servlet-class>org.codehaus.xfire.spring.XFireSpringServlet</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/servlet/XFireServlet/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>XFireServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:org/codehaus/xfire/spring/xfire.xml,/WEB-INF/applicationContext.xml</param-value> </context-param>

xfire不整合spring時，使用

org.codehaus.xfire.transport.http.XFireConfigurableServlet

xfire整合spring時，使用

org.codehaus.xfire.spring.XFireSpringServlet
