public interface UserDAO {
public abstract boolean isValidUser(String username, String password);
}
UserDAOImp.java
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.test.Hibernate.SessionFactory;
public class UserDAOImp extends HibernateDaoSupport implements UserDAO {
private SessionFactory sessionFactory;
private static String hql = "from User u where u.username=? ";
public boolean isValidUser(String username, String password) {
List userList = this.getHibernateTemplate().find(hql, username);
if (userList.size() > 0) {
return true;
}
return false;
}
}
修改LoginAction.java文件，使用userDao的方法來進(jìn)行用戶驗證
package com.test.struts.action;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.DynaValidatorForm;
import com.test.UserDAO;
public class LoginAction extends Action {
private UserDAO userDAO;
public UserDAO getUserDAO() {
return userDAO;
}
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
DynaValidatorForm loginForm = (DynaValidatorForm) form;
// TODO Auto-generated method stub
String username = (String) loginForm.get("username");
String password = (String) loginForm.get("password");
loginForm.set("password", null);
if (userDAO.isValidUser(username,password)) {
return mapping.findForward("indexGo");
} else {
return mapping.getInputForward();
}
}
}
綠色字體為修改部份
現(xiàn)在剩下最后的spring配置了

現(xiàn)在可以進(jìn)行測試了！
在編寫代碼有配置內(nèi)容時一定要注意 hibernate 和 hibernate3 ，這兩個包的名字就只差一個字，千萬不要有錯，否則找錯誤可是很難的。
