mysql數據庫表已經字段：
項目文件結構：
調試過程中要注意的事項：
①：applicationContext.xml文件要放在src目錄下
②：容易出錯的地方如下代碼中字體為紅色處
常見錯誤請參看：http://blog.163.com/jxguo_05/blog/static/71940100201023185653156/ &

各工具版本：struts2.3.4 、hibernate 3.6.0 spring3.1.3
jar包：如下：下載地址：http://download.csdn.net/detail/sxf1997/7976797
這里是一個簡單的利用ssh整合的頁面登陸界面
代碼如下：

登陸頁面處理的action
package Action;
import java.util.List;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import DAO.UserDao;
import PO.User;
import com.opensymphony.xwork2.ActionSupport;
public class LoginServiceAction extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;
/**
*
*/
private String username;
private String password;
<span style="color:#ff0000;">ClassPathXmlApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml");</span>
UserDao userDao=(UserDao) ctx.getBean("userDao");
/**

}

public void setUsername(String username) {
this.username = username;

*/
public String getPassword() {

}
/**

*/
public void setPassword(String password) {
this.password = password;
}
/* (non-Javadoc)

*/
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
//查找賬號相符的用戶
List<User>userlist=userDao.findByName(username);
//使用簡化的for語句對集合進行遍歷并比較用戶的密碼
for(User user : userlist){
if(user.getPassword().equals(password)){
return SUCCESS;
}else {
return ERROR;
}
}
return ERROR;
}
}
處理方法的接口 （ DAO包）
package DAO;
import java.util.List;
import PO.User;
public interface UserDao {
/**
* 加載User實例
* @參數id知道需要加載的User實例的主鍵值
* @return 返回加載的User實例
* */
User get(Integer id);
/**
* 保存User實例
* @參數user知道需要保存的User實例
* @return 返回剛剛保存的User實例的標識屬性值
* */
Integer save(User user);
/**
* 根據用戶名查找User
* @參數那么知道查詢的用戶名
* @return返回用戶名對呀的全部User
* */
List<User>findByName(String name);
}
實現接口的類ImplDao.UserImpl
package ImplDao;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import DAO.UserDao;
import PO.User;
public class UserDaoImpl implements UserDao {
//實例化一個HibernateTemplate對象，用于執行持久化操作
private HibernateTemplate ht=null;
//Hibernate持久化操作所需SessionFactory
private SessionFactory sessionFactory=null;
//用戶依賴注入的setter方法
public void setSessionFactory(SessionFactory sessionFactory){
this.sessionFactory=sessionFactory;
}
//初始化HibernateTemplate方法
private HibernateTemplate gethiHibernateTemplate(){
if(ht==null){
ht=new HibernateTemplate(sessionFactory);
}
return ht;
}
@Override
public User get(Integer id) {
// TODO Auto-generated method stub
//獲取對應表中id為某個值的數據，id為主鍵索引
return gethiHibernateTemplate().get(User.class, id);
}
@Override
public Integer save(User user) {
// TODO Auto-generated method stub
return (Integer)gethiHibernateTemplate().save(user);
}
@SuppressWarnings("unchecked")
@Override
public List<User> findByName(String name) {
// TODO Auto-generated method stub
return (List<User>)gethiHibernateTemplate().find("from User u where u.name=?",name);
}
}
PO（hibernate映射數據表的字段）
package PO;
import java.io.Serializable;
public class User implements Serializable{
/**
*
*/
private static final long serialVersionUID = 6810795086071173792L;
private Integer intId;
private String name;
private String password;
public User(){}
public User(Integer intId,String name,String password){
this.intId=intId;
this.name=name;

}
/**
