MyBatis Insert: Add Database Data

To add data to the database, you need to use MyBatis insert statements. Here are the general steps for adding data to the database using MyBatis:

  1. Mapping of users
public interface UserMapper {
    @Insert("INSERT INTO users (id, name, email) VALUES (#{id}, #{name}, #{email})")
    void insertUser(User user);
}
  1. “Please include all the necessary information in your report.”
  2. The xml file for mapping users
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.example.UserMapper">
    <insert id="insertUser" parameterType="com.example.User">
        INSERT INTO users (id, name, email)
        VALUES (#{id}, #{name}, #{email})
    </insert>
</mapper>
  1. – Database session
  2. – place()
SqlSession sqlSession = sqlSessionFactory.openSession();
try {
    UserMapper userMapper = sqlSession.getMapper(UserMapper.class);

    User user = new User();
    user.setId(1);
    user.setName("John");
    user.setEmail("john@example.com");

    userMapper.insertUser(user);

    sqlSession.commit();
} finally {
    sqlSession.close();
}

In this way, MyBatis will insert the attribute values of the User object into the database table.
