spring3 struts2框架整合错误，提示说action类注入错误

No bean named 'userService' is defined
Error creating bean with name 'action.UserAction': Injection of resource methods failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'userService' is defined
Unable to instantiate Action, action.UserAction, defined for 'user' in namespace '/'Error creating bean with name 'action.UserAction': Injection of resource methods failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'userService' is defined

这个提示已经够明显了吧，在你的UserAction里声明的userService注入出错，找不到相应的id="userService"的bean，检查一下是不是配置文件命名写错了，如果service是注入形式的，那么检查下@Service("userService")有没有写错

 ApplicationContext context = new ClassPathXmlApplicationContext("spring/applicationContext.xml");
    使用context.getBean("？");自己获取bean，看看是不是没注册上。
