采用注解实现实体类文件User.java:

import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.Id;import javax.persistence.Table;import org.hibernate.annotations.GenericGenerator;@Entity@Table(name="myuser")public class User {@Id@GeneratedValue(generator="system-uuid")@GenericGenerator(name = "system-uuid",strategy="uuid")@Column(length=32)private String id;@Column(length=32)private String name;@Column(length=32)private String password;public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

实体类操作接口UseDao.java:

public interface UserDao {public String check(String name,String password);}

具体实现类UserDaoimpl.java:

import java.util.List;import javax.management.Query;import org.hibernate.Session;import org.hibernate.SessionFactory;public class UserDaoimpl implements UserDao{private SessionFactory sessionFactory;public void setSessionFactory(SessionFactory sessionFactory) {this.sessionFactory = sessionFactory;}@Overridepublic String check(String name, String password) {String hql = "select user.name ,user.password from User as user where user.name='"+name+"' and user.password ='"+password+"'";org.hibernate.Query query = sessionFactory.getCurrentSession().createQuery(hql);List list = query.list();  if (list.size() > 0) {return "ok";}return "no";}}

管理接口Manager.java:

public interface Manager {public String check(String name,String password); }

管理实现类ManagerImpl.java:

import com.dao.UserDao;public class ManagerImpl implements Manager{private UserDao userDao;public void setUserDao(UserDao userDao) {this.userDao = userDao;}public String check(String name,String password) {return userDao.check(name, password);}}

控制类Controler.java:

import javax.annotation.Resource;import javax.enterprise.inject.Model;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import com.dao.UserDao;import com.eneity.User;import com.manager.Manager;@Controller@RequestMapping("/login")public class Controler {@Resourceprivate Manager manager;public void setManager(Manager manager) {this.manager = manager;}@RequestMapping("/check")public String check(User user,org.springframework.ui.Model model) {String string = manager.check(user.getName(), user.getPassword());if (string.equals("ok")) {model.addAttribute("name",user.getName());return "/ok";}return "/no";}}

登录主页面index.jsp(加入了BootStrap实现效果)：

ok.jsp和no.jsp就不给出了,最终实现效果：
