mysql数据库表已经字段：

项目文件结构：

调试过程中要注意的事项：

①：applicationContext.xml文件要放在src目录下

②：容易出错的地方如下代码中字体为红色处

常见错误请参看：http://blog.163.com/jxguo_05/blog/static/71940100201023185653156/ & http://blog.sina.com.cn/s/blog_6757442e0100xumy.html &

http://blog.csdn.net/yabushandaxue/article/details/39473593

各工具版本：struts2.3.4 、hibernate 3.6.0 spring3.1.3

jar包：如下：下载地址：http://download.csdn.net/detail/sxf1997/7976797

这里是一个简单的利用ssh整合的页面登陆界面

代码如下：

登陆页面处理的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");
	/**
	 * @return the username
	 */
	public String getUsername() {
		return username;
	}
	/**
	 * @param username the username to set
	 */
	public void setUsername(String username) {
		this.username = username;
	}
	/**
	 * @return the password
	 */
	public String getPassword() {
		return password;
	}
	/**
	 * @param password the password to set
	 */
	public void setPassword(String password) {
		this.password = password;
	}
	/* (non-Javadoc)
	 * @see com.opensymphony.xwork2.ActionSupport#execute()
	 */
	@Override
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		//查找账号相符的用户
		List<User>userlist=userDao.findByName(username);
		//使用简化的for语句对集合进行遍历并比较用户的密码
		for(User user : userlist){
			if(user.getPassword().equals(password)){
				return SUCCESS;
			}else {
				return ERROR;
			}
		}
		return ERROR;
	}
	

}


处理方法的接口 （ DAO包）

package DAO;

import java.util.List;

import PO.User;

public interface UserDao {
	/**
	 * 加载User实例
	 * @参数id知道需要加载的User实例的主键值
	 * @return 返回加载的User实例
	 * */
	User get(Integer id);
	
	
	/**
	 * 保存User实例
	 * @参数user知道需要保存的User实例
	 * @return 返回刚刚保存的User实例的标识属性值
	 * */
	
	Integer save(User user);
	
	/**
	 * 根据用户名查找User
	 * @参数那么知道查询的用户名
	 * @return返回用户名对呀的全部User
	 * */
	List<User>findByName(String name);
}

实现接口的类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 {

	//实例化一个HibernateTemplate对象，用于执行持久化操作
	private HibernateTemplate ht=null;
	//Hibernate持久化操作所需SessionFactory
	private SessionFactory sessionFactory=null;
	//用户依赖注入的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
		//获取对应表中id为某个值的数据，id为主键索引
		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映射数据表的字段）
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;
		this.password=password;
	}
	/**
	 * @return the intId
	 */
	public Integer getIntId() {
		return intId;
	}
	/**
	 * @param intId the intId to set
	 */
	public void setIntId(Integer intId) {
		this.intId = intId;
	}
	/**
	 * @return the name
	 */
	public String getName() {
		return name;
	}
	/**
	 * @param name the name to set
	 */
	public void setName(String name) {
		this.name = name;
	}
	/**
	 * @return the password
	 */
	public String getPassword() {
		return password;
	}
	/**
	 * @param password the password to set
	 */
	public void setPassword(String password) {
		this.password = password;
	}
}


User.hbm.xml(PO对象的映射文件)
