java - 现有spring项目整合cxf出现class not found cxfservlet

在原有ssh项目上整合cxf时报错

严重: Servlet [HelloWorldService] in web application [/admin_iqiyi] threw load() exception

查了半天都说是未导jar包或者未配置cxf servlet，但是我都引入了
web.xml

    
        HelloWorldService    
        org.apache.cxf.transport.servlet.CXFServlet    
        1 
        
            config-location
            /WEB-INF/beans.xml
           
        
        
        HelloWorldService    
        /service/*    
    

cxf配置文件

    
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd    
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">    
    
        
        
        
    
        
    
        
    
    
 

实在是搞不明白是怎么回事，求指导
