MyBatis offers various methods for performing query operations, including querying data by name. The steps for querying data by name using MyBatis are as follows:

  1. Develop a Mapper interface for defining query methods. For example:
public interface UserMapper {
    User findByName(String name);
}
  1. Write the query statement in the XML file corresponding to the Mapper interface. For example:
<select id="findByName" resultType="com.example.User">
    SELECT * FROM user WHERE name = #{name}
</select>
  1. Set the paths for Mapper interface and XML file in the configuration file. For example:
<mappers>
    <mapper resource="com/example/UserMapper.xml"/>
</mappers>
  1. Perform query operations using MyBatis’s SqlSession object. For example:
SqlSession sqlSession = sqlSessionFactory.openSession();
try {
    UserMapper userMapper = sqlSession.getMapper(UserMapper.class);
    User user = userMapper.findByName("John");
    System.out.println(user);
} finally {
    sqlSession.close();
}

The above are the basic steps for querying data based on names. You can make adjustments and modifications according to your specific needs.
