How to embed cxf into spring

[lv]

I　embed cxf 2.4 to spring. WSDL is created by java code. But methods in server 
level cannot be invoked.
Error messages are: 
 [http-8080-1] INFO  org.apache.cxf.phase.PhaseInterceptorChain - Application 
{http://com.ws}webServiceSrcSecurity#{http://com.ws}ComService has thrown 
exception, unwinding now: java.lang.reflect.InvocationTargetException: null


public class WebServiceSecurity{
        
        @Autowired
        public WebServiceSecurityService webServiceSecurityService;
        
        public WebServiceSecurity(){}
 
        private String EditOrder(Integer type, Integer startNo, Integer endNo){
                
                return webServiceSecurityService.EditOrder( type, startNo, 
endNo);
        }
