2. Create table users 

CREATE TABLE users (
   id INT NOT NULL auto_increment,
   username VARCHAR(30) default NULL,
   password  VARCHAR(32) default NULL,
   PRIMARY KEY (id)
);

INSERT INTO users('username', 'password') VALUES ("admin", "12345678");

3. Create model Users

Create model Users in package com.realtut.model.

File: Users.java 

package com.realtut.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import static javax.persistence.GenerationType.IDENTITY;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "users", catalog = "testdb")
public class Users implements java.io.Serializable {

    private Integer id;
    private String username;
    private String password;

    public Users() {
    }

    public Users(String username, String password) {
        this.username = username;
        this.password = password;
    }

    @Id
    @GeneratedValue(strategy = IDENTITY)

    @Column(name = "id", unique = true, nullable = false)
    public Integer getId() {
        return this.id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    @Column(name = "username", length = 30)
    public String getUsername() {
        return this.username;
    }

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

    @Column(name = "password", length = 32)
    public String getPassword() {
        return this.password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

4. Create UserDao interface

File: UserDao.java 

package com.realtut.dao;

import com.realtut.model.Users;

public interface UserDao {
 public Users findByUserName(String username);
}

5. Create UserDaoImpl class

File: UserDaoImpl .java 

package com.realtut.dao;

import java.util.ArrayList;
import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import com.realtut.model.Users;

@Repository
public class UserDaoImpl implements UserDao {
    @Autowired
    private SessionFactory sessionFactory;

    public Users findByUserName(String username) {
        Session session = null;

        try {
            session = sessionFactory.openSession();
            List<Users> users = new ArrayList<Users>();
            users = session.createQuery("from Users where username=?")
                    .setParameter(0, username).list();
            if (users.size() > 0) {
                return users.get(0);
            }
        } catch (HibernateException e) {
            e.printStackTrace();
        }
        return null;
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

6. Create UserService class

File: UserService.java 

package com.realtut.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.realtut.dao.UserDao;
import com.realtut.model.Users;

@Service("userService")
public class UserService {
    @Autowired
    private UserDao userDao;

    public boolean isUsers(String username, String password) {
        Users user = userDao.findByUserName(username);
        if (user != null && user.getPassword().equals(password)) {
            return true;
        }
        return false;
    }

    public UserDao getUserDao() {
        return userDao;
    }

    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
}

7. Update web.xml

        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

8. Spring annotation configuration class

File: ApplicationConfig.java 

package com.realtut.config;

import java.io.IOException;
import java.util.Properties;

import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

import com.realtut.dao.UserDaoImpl;

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = { "com.realtut" })
@PropertySource("classpath:application.properties")
public class ApplicationConfig {

    @Autowired
    Environment evn;

    @Bean
    public InternalResourceViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setViewClass(JstlView.class);
        viewResolver.setPrefix("/WEB-INF/view/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

    @Bean
    public DriverManagerDataSource dataSource() throws IOException {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(evn.getProperty("jdbc.driverClassName"));
        dataSource.setUrl(evn.getProperty("jdbc.url"));
        dataSource.setUsername(evn.getProperty("jdbc.username"));
        dataSource.setPassword(evn.getProperty("jdbc.password"));
        return dataSource;
    }

    @Bean
    public LocalSessionFactoryBean sessionFactory() throws IOException {
        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
        sessionFactory.setDataSource(dataSource());
        sessionFactory.setPackagesToScan(new String[] { "com.realtut.model" });
        sessionFactory.setHibernateProperties(hibernateProperties());
        return sessionFactory;
    }

    @Bean
    @Autowired
    public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) {
        HibernateTransactionManager txManager = new HibernateTransactionManager();
        txManager.setSessionFactory(sessionFactory);
        return txManager;
    }

    @Bean
    @Autowired
    public UserDaoImpl userDao(SessionFactory sessionFactory) {
        UserDaoImpl userDao = new UserDaoImpl();
        userDao.setSessionFactory(sessionFactory);
        return userDao;
    }

    Properties hibernateProperties() {
        return new Properties() {
            {
                setProperty("hibernate.dialect", evn.getProperty("hibernate.dialect"));
                setProperty("hibernate.format_sql", evn.getProperty("hibernate.format_sql"));
                setProperty("hibernate.show_sql", evn.getProperty("hibernate.show_sql"));
