Mybatis batch 批量处理

@Test
public void batch() throws IOException {
    InputStream inputStream= Resources.getResourceAsStream("mybatis-config.xml");
    //读取mybatis 配置文件创建sqlsessionFactory
    SqlSessionFactory sqlSessionFactory= new SqlSessionFactoryBuilder().build(inputStream);
    inputStream.close();
    //获取sqlsession
    SqlSession sqlSession=sqlSessionFactory.openSession(ExecutorType.BATCH,false); //默认 single
    //获取对应mapper
    userMapper mapper=sqlSession.getMapper(userMapper.class);

    user userobj1=new user();
    userobj1.setId(1);
    userobj1.setName("11");
    mapper.insert(userobj1);

    user userobj2=new user();
    userobj2.setId(1);
    userobj2.setName("11");
    mapper.insert(userobj2);

    sqlSession.commit();
}

mybatis  有三种执行器

package org.apache.ibatis.session;

public enum ExecutorType {
    SIMPLE,     //默认 普通执行器
    REUSE,      // 重用预处理语句  (prepared statement)
    BATCH;       //重用语句并执行批量更新

    private ExecutorType() {
    }
}
