求大家帮我看一下，告诉我该怎么做

action层
BaseAction.java
package common.action;
import java.text.SimpleDateFormat;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.interceptor.ServletRequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionSupport;import common.serive.BaseService;
import common.serive.BasicHibernateSerive;@SuppressWarnings("serial")
public class BaseAction extends ActionSupport implements ServletRequestAware,ServletResponseAware,SessionAware {
    
    protected HttpServletRequest request;
protected HttpServletResponse response;
@SuppressWarnings("unchecked")
protected Map map;
public BasicHibernateSerive basicHibernateSerive;protected void setHead(){
response.setCharacterEncoding("utf-8");
}
public String execute() throws Exception {
return null;
}
/**
 * @param request the request to set
 */
public void setServletRequest(HttpServletRequest request) {
this.request = request;
}/**
 * @param response the response to set
 */
public void setServletResponse(HttpServletResponse response) {
this.response = response;
}
/**
 */
public void setSession(Map<String, Object> arg0) {
this.map = arg0;
}public void setBasicHibernateSerive(BasicHibernateSerive basicHibernateSerive) {
this.basicHibernateSerive = basicHibernateSerive;
}
}
Serive层
BasicHibernateSerive.javapackage common.serive;import common.HibernateDao.Dao;
public class BasicHibernateSerive {
public void setDao(Dao dao) {
this.dao = dao;
}} 
impl层
BaiscHibernateImpl.java
package common.dao.impl;import java.util.Iterator;import org.hibernate.Query;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;import common.HibernateDao.Dao;public class BaiscHibernateImpl extends HibernateDaoSupport implements Dao{public BaiscHibernateImpl() {}
public <T> Iterator<T> save(String hql) {
Query query = getSession().createQuery(hql);
return query.iterate();
}
  public void save(Object obj){
        getSession().save(obj);
    }public <T> T queryOneResult(String hql) {
Query query = getSession().createQuery(hql);
     query.setMaxResults(1);
     return (T)query.uniqueResult();
}
}
spring配置如下

请问我这哪配置不对，为什么this.basicHibernateSerive.dao为什么为null
