Mybatis-Flex 和同类框架「性能」对比

本文主要是展示了 Mybatis-Flex 和 Mybaits-Plus 的「性能」对比。Mybaits-Plus 是一个非常优秀 Mybaits 增强框架， 其开源于 2016 年，有很多的成功案例。

本文只阐述了「性能」方面的对比，「功能」对比请参考 这里。

测试方法

使用 h2 数据库，在初始化的时候分别为 mybatis-flex 和 mybatis-plus 创建两个不同的数据库， 但是完全一样的数据结构、数据内容和数据量（每个库 2w 条数据）。

开始之前先进行预热，之后通过打印时间戳的方式进行对比，谁消耗的时间越少，则性能越高（每次测试 10 轮）。

::: tip 测试说明

在以下的所有测试中，有可能因为每个人的电脑性能不同，测试的结果会有所不同。 :::

测试单条数据查询

Mybatis-Flex 的代码如下：

QueryWrapper queryWrapper = new QueryWrapper();
queryWrapper.where(FLEX_ACCOUNT.ID.ge(100)
.or(FLEX_ACCOUNT.USER_NAME.eq("admin" + ThreadLocalRandom.current().nextInt(10000))));
mapper.selectOneByQuery(queryWrapper);

Mybatis-Plus 的代码如下：

QueryWrapper queryWrapper = new QueryWrapper();
queryWrapper.ge("id", 100);
queryWrapper.or();
queryWrapper.eq("user_name", "admin" + ThreadLocalRandom.current().nextInt(10000));
queryWrapper.last("limit 1");
mapper.selectOne(queryWrapper);

::: tip 测试结论

Mybatis-Flex 的查询单条数据的速度，大概是 Mybatis-Plus 的 5 ~ 8 倍。 :::

测试列表(List)数据查询

要求返回的数据为 10 条数据。

Mybatis-Flex 的代码如下：

QueryWrapper queryWrapper = new QueryWrapper();
queryWrapper.where(FLEX_ACCOUNT.ID.ge(100).or(FLEX_ACCOUNT.USER_NAME
.eq("admin" + ThreadLocalRandom.current().nextInt(10000))))
.limit(10);
mapper.selectListByQuery(queryWrapper);

Mybatis-Plus 的代码如下：

QueryWrapper queryWrapper = new QueryWrapper();
queryWrapper.ge("id", 100);
queryWrapper.or();
queryWrapper.eq("user_name", "admin" + ThreadLocalRandom.current().nextInt(10000));
queryWrapper.last("limit 10");
mapper.selectList(queryWrapper);

>>>>>>>testPlusSelectTop10:77

::: tip 测试结论

Mybatis-Flex 的查询 10 条数据的速度，大概是 Mybatis-Plus 的 5 倍左右。 :::

分页查询

Mybatis-Flex 的代码如下：

QueryWrapper queryWrapper = new QueryWrapper()
    .where(FLEX_ACCOUNT.ID.ge(100))
    .or(FLEX_ACCOUNT.USER_NAME.like("admin"))
    .or(FLEX_ACCOUNT.NICKNAME.eq("Michael"))
    .or(FLEX_ACCOUNT.EMAIL.eq("michael@gmail.com"));
mapper.paginate(page, pageSize, 10000, queryWrapper);

Mybatis-Plus 的代码如下：

LambdaQueryWrapper<PlusAccount> queryWrapper = new LambdaQueryWrapper<>();
    queryWrapper.ge(PlusAccount::getId, 100);
    queryWrapper.or();
    queryWrapper.like(PlusAccount::getUserName, "admin");
    queryWrapper.or();
    queryWrapper.eq(PlusAccount::getNickname, "Michael");
    queryWrapper.or();
    queryWrapper.eq(PlusAccount::getEmail, "michael@gmail.com");
Page<PlusAccount> p = Page.of(page,pageSize,10000, false);
mapper.selectPage(p, queryWrapper);

数据更新

Mybatis-Flex 的代码如下：

FlexAccount flexAccount = new FlexAccount();
flexAccount.setUserName("testInsert" + i);
flexAccount.setNickname("testInsert" + i);
flexAccount.addOption("key1", "value1");
flexAccount.addOption("key2", "value2");
flexAccount.addOption("key3", "value3");
flexAccount.addOption("key4", "value4");
flexAccount.addOption("key5", "value5");

QueryWrapper queryWrapper = QueryWrapper.create()
    .where(FLEX_ACCOUNT.ID.ge(9200))
    .and(FLEX_ACCOUNT.ID.le(9300))
    .and(FLEX_ACCOUNT.USER_NAME.like("admin"))
    .and(FLEX_ACCOUNT.NICKNAME.like("admin"));

mapper.updateByQuery(flexAccount, queryWrapper);

Mybatis-Plus 的代码如下：

PlusAccount plusAccount = new PlusAccount();
plusAccount.setUserName("testInsert" + i);
plusAccount.setNickname("testInsert" + i);
plusAccount.addOption("key1", "value1");
plusAccount.addOption("key2", "value2");
plusAccount.addOption("key3", "value3");
plusAccount.addOption("key4", "value4");
plusAccount.addOption("key5", "value5");

LambdaUpdateWrapper<PlusAccount> updateWrapper = new LambdaUpdateWrapper<>();
updateWrapper.ge(PlusAccount::getId, 9000);
updateWrapper.le(PlusAccount::getId, 9100);
updateWrapper.like(PlusAccount::getUserName, "admin");
updateWrapper.like(PlusAccount::getNickname, "admin");

mapper.update(plusAccount, lambdaUpdateWrapper);
