我用basedao注入



public class BaseDAO1 extends HibernateDaoSupport{

@Resource
public void setSuperSessionFactory(SessionFactory sessionFactory){
super.setSessionFactory(sessionFactory);
}

}


然后功能dao

public class carrieruserinfoDAO extends BaseDAO1 {

public void save(carrieruserinfo transientInstance) {
log.debug("saving carrieruserinfo instance");
try {
getSession().save(transientInstance);
log.debug("save successful");
} catch (RuntimeException re) {
log.error("save failed", re);
throw re;
}

public List findAll() {
log.debug("finding all carrieruserinfo instances");
try {
String queryString = "from carrieruserinfo";
Query queryObject = getSession().createQuery(queryString);
return queryObject.list();
} catch (RuntimeException re) {
log.error("find all failed", re);
throw re;
}
}

}
}

action:

public class LoginAction extends BaseAction{

/**

*/
private static final long serialVersionUID = 1L;


public String findAll(){
 carrieruserinfoDAO carrieruserinfoDAO=new carrieruserinfoDAO();
carrieruserinfoDAO.findAll(); 
 
return "success";
}

最后调用报

HTTP Status 500 -


type Exception report
