五、添加相关类


   1.entity


-
package com.ssh.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
/**
 * Created by mk on 2017/8/5.
 */
@Entity(name="t_user")
public class UserEntity {
    @Id
    @GeneratedValue
    private int id;
    private String name;
    private String password;
    public int getId() {
        return id;
    }
    public void setId(int 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;
    }
}
-


   2.Dao


-
package com.ssh.dao;
import com.ssh.entity.UserEntity;
/**
 * Created by mk on 2017/8/5.
 */
public interface UserDao {
    public int insert(UserEntity userEntity);
}
-


   3.DaoImpl


-
package com.ssh.dao.impl;
import com.ssh.dao.UserDao;
import com.ssh.entity.UserEntity;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
/**
 * Created by mk on 2017/8/5.
 */
@Repository
public class UserDaoImpl implements UserDao {
    @Autowired
    SessionFactory sessionFactory;
    public int insert(UserEntity userEntity) {
        Session session = sessionFactory.getCurrentSession();
        return (Integer)session.save(userEntity);
    }
}
-


   4.Service


-
package com.ssh.service;
import com.ssh.entity.UserEntity;
/**
 * Created by mk on 2017/8/5.
 */
public interface UserService {
    public int insert(UserEntity userEntity);
}
-


   5.ServiceImpl


-
package com.ssh.service.impl;
import com.ssh.dao.UserDao;
import com.ssh.entity.UserEntity;
import com.ssh.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
/**
 * Created by mk on 2017/8/5.
 */
@Service
public class UserServiceImpl implements UserService {
    @Autowired
    UserDao userDao;
    public int insert(UserEntity userEntity) {
        return userDao.insert(userEntity);
    }
}
-


   6.Controller


-
package com.ssh.controller;
import com.ssh.entity.UserEntity;
import com.ssh.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
/**
 * Created by mk on 2017/8/5.
 */
@RequestMapping("/user1")
@Controller
public class userController {
    @Autowired
    UserService userService;
    @RequestMapping("/testindex")
    public String inset(Model model){
        UserEntity userEntity = new UserEntity();
        userEntity.setName("1");
        userEntity.setPassword("123");
        int result = userService.insert(userEntity);
        model.addAttribute("result",result);
        return "/test";
    }
}
-


外.text.jsp

</html>
-


六、建立数据库相关内容


   1.建立数据库


20170807113617679.png


   2.建立表(和entity中的字段类型对应)


-
CREATE TABLE `t_user` (
  `id` int(100) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `password` varchar(255) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=18 DEFAULT CHARSET=utf8;
-


七、配置tomcat
