Spring整合XFire的注入问题

2009-11-21 00:53 351 查看

给WebService注入其他类的时候，报空指针错误。

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>

结果当webservice调用webservice服务时，报错：

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

这个问题可以通过如下配置解决。

<servlet>
  <servlet-name>XFireServlet</servlet-name>
  <!-- 不整合时使用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时，使用

org.codehaus.xfire.transport.http.XFireConfigurableServlet

xfire整合spring时，使用

org.codehaus.xfire.spring.XFireSpringServlet
