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

public class StudentTest {

    public static void main(String[] args) {
        String resource = "com/hbk/map/mybatis-config.xml";
        try {
            Reader reader = Resources.getResourceAsReader(resource);
            SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(reader);
            SqlSession sqlSession = sqlSessionFactory.openSession();
            sqlSession.update("deleteById", 2);
            sqlSession.commit();
            sqlSession.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
