求助cxf+ssh2注入dao为null的问题

求助关于CXF整合SSH2框架之后依赖注入为空的问题，如果不注入bean是可以正常使用的，但所有注入的dao都是null，网上的帖子也搜了不少，也有专门说这个问题的，说是要加上<jaxws:implementor ref=""/>，但好多帖子上的方法都试过了，问题依然存在接口：
package com.payment.cxf;import javax.jws.WebService;@WebService
public interface CheckLogin { /**
 * 用户登录验证，返回一个字符串
 * 
 * @param username
 * @return
 */
public String checkLogin(String account, String password, Integer iid);

}实现类
package com.payment.cxf.impl;import javax.annotation.Resource;
import javax.jws.WebService;import org.springframework.stereotype.Component;import com.payment.cxf.CheckLogin;
import com.payment.dao.UserDao;
import com.payment.model.User;/**
 * WebService实现类.
 * 
 * 使用@WebService指向Interface定义类即可.
 */
@WebService(endpointInterface = "com.payment.cxf.CheckLogin")
@Component(value="checkLoginImpl")
public class CheckLoginImpl implements CheckLogin { private UserDao userDao; public UserDao getUserDao() {
return userDao;
} @Resource
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}

public String checkLogin(String account, String password, Integer iid) {
User user = userDao.load(account, password, iid);
if (user != null) {
return "ok";
} else {
return "error";
}
}}
