 User类：

package com.baizhidu;

import java.io.Serializable;

public class User implements Serializable {
    private Integer id;
    private String name;
    private String password;

    public User() {
    }

    public User(Integer id, String name, String password) {
        this.id = id;
        this.name = name;
        this.password = password;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer 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;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + ''' +
                ", password='" + password + ''' +
                '}';
    }
}

mybatis-config.xml主配置文件：

UserDAO接口：

package com.baizhidu;

public interface UserDao {
    public void save(User user);
}

配置文件，UserDAOMapper.xml:

    

    
        insert into tb_users(name,password) values (#{name},#{password})
    

TestMyBatis类：

package com.baizhidu;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;


import java.io.IOException;
import java.io.InputStream;

public class TestMyBatis {
    public static void main(String[] args) throws IOException {
        InputStream inputStream= Resources.getResourceAsStream("mybatis-config.xml");
        //获得工厂
        SqlSessionFactory sqlSessionFactory=new SqlSessionFactoryBuilder().build(inputStream);

        //获取session
        SqlSession session=sqlSessionFactory.openSession();
        UserDao userDao=session.getMapper(UserDao.class);//获取dao代理对象

        User user=new User();
        user.setName("suns");
        user.setPassword("123456");
        userDao.save(user);

        session.commit();//update、delete、insert需要自动提交


    }
}
