单条语句插入多个值

@Mapper
public interface UserMapper {
void batchSave(List<User> userList);
}

<insert id="batchSave">
insert into user(name, password) values
<foreach collection="list" item="user" separator=",">
(#{user.name}, #{user.password})
</foreach>
</insert>

@RunWith(SpringRunner.class)
@SpringBootTest
public class SbMybatis02ApplicationTests {
@Test
public void testBatchSave(){
User user1 = new User();
user1.setName("关羽");
user1.setPassword("guanyu");
User user2 = new User();
user2.setName("张飞");
user2.setPassword("zhangfei");
List<User> userList
= new ArrayList<>();
userList.add(user1);
userList.add(user2);
userMapper.batchSave(userList);
}
}

多条语句插入多个值

@Mapper

}

<insert id="batchSave">
<foreach collection="list" item="user" separator=";">

(#{user.name}, #{user.password})
</foreach>
</insert>

@RunWith(SpringRunner.class)

}
}
