# 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](./comparison.md)。 ## 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）。 测试源码： [https://gitee.com/mybatis-flex/mybatis-benchmark](https://gitee.com/mybatis-flex/mybatis-benchmark) ::: 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： ```java 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： ```java 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); ``` 10 轮的测试结果： ``` --------------- >>>>>>>testFlexSelectOne:134 >>>>>>>testPlusSelectOneWithLambda:989 >>>>>>>testPlusSelectOne:830 --------------- >>>>>>>testFlexSelectOne:75 >>>>>>>testPlusSelectOneWithLambda:732 >>>>>>>testPlusSelectOne:795 --------------- >>>>>>>testFlexSelectOne:65 >>>>>>>testPlusSelectOneWithLambda:938 >>>>>>>testPlusSelectOne:714 --------------- >>>>>>>testFlexSelectOne:105 >>>>>>>testPlusSelectOneWithLambda:740 >>>>>>>testPlusSelectOne:669 --------------- >>>>>>>testFlexSelectOne:57 >>>>>>>testPlusSelectOneWithLambda:691 >>>>>>>testPlusSelectOne:773 --------------- >>>>>>>testFlexSelectOne:65 >>>>>>>testPlusSelectOneWithLambda:693 >>>>>>>testPlusSelectOne:695 --------------- >>>>>>>testFlexSelectOne:56 >>>>>>>testPlusSelectOneWithLambda:754 >>>>>>>testPlusSelectOne:665 --------------- >>>>>>>testFlexSelectOne:56 >>>>>>>testPlusSelectOneWithLambda:714 >>>>>>>testPlusSelectOne:717 --------------- >>>>>>>testFlexSelectOne:57 >>>>>>>testPlusSelectOneWithLambda:696 >>>>>>>testPlusSelectOne:671 --------------- >>>>>>>testFlexSelectOne:59 >>>>>>>testPlusSelectOneWithLambda:739 >>>>>>>testPlusSelectOne:659 ``` ::: tip 测试结论 > MyBatis-Flex 的查询单条数据的速度，大概是 MyBatis-Plus 的 5 ~ 10+ 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： ```java 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： ```java 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); ``` 10 轮的测试结果： ``` --------------- >>>>>>>testFlexSelectTop10:90 >>>>>>>testPlusSelectTop10WithLambda:743 >>>>>>>testPlusSelectTop10:678 --------------- >>>>>>>testFlexSelectTop10:85 >>>>>>>testPlusSelectTop10WithLambda:692 >>>>>>>testPlusSelectTop10:684 --------------- >>>>>>>testFlexSelectTop10:84 >>>>>>>testPlusSelectTop10WithLambda:692 >>>>>>>testPlusSelectTop10:670 --------------- >>>>>>>testFlexSelectTop10:85 >>>>>>>testPlusSelectTop10WithLambda:737 >>>>>>>testPlusSelectTop10:667 --------------- >>>>>>>testFlexSelectTop10:85 >>>>>>>testPlusSelectTop10WithLambda:691 >>>>>>>testPlusSelectTop10:684 --------------- >>>>>>>testFlexSelectTop10:97 >>>>>>>testPlusSelectTop10WithLambda:760 >>>>>>>testPlusSelectTop10:666 --------------- >>>>>>>testFlexSelectTop10:80 >>>>>>>testPlusSelectTop10WithLambda:673 >>>>>>>testPlusSelectTop10:637 --------------- >>>>>>>testFlexSelectTop10:81 >>>>>>>testPlusSelectTop10WithLambda:653 >>>>>>>testPlusSelectTop10:639 --------------- >>>>>>>testFlexSelectTop10:82 >>>>>>>testPlusSelectTop10WithLambda:659 >>>>>>>testPlusSelectTop10:636 --------------- >>>>>>>testFlexSelectTop10:81 >>>>>>>testPlusSelectTop10WithLambda:654 >>>>>>>testPlusSelectTop10:656 ``` ::: tip 测试结论 MyBatis-Flex 的查询 10 条数据的速度，大概是 MyBatis-Plus 的 5~10 倍左右。 ::: ## 分页查询 MyBatis-Flex 的代码如下： ```java QueryWrapper queryWrapper = new QueryWrapper() .where(FLEX_ACCOUNT.ID.ge(100)); mapper.paginate(page, pageSize, 20000, queryWrapper); ``` MyBatis-Plus 的代码如下： ```java LambdaQueryWrapper queryWrapper = new LambdaQueryWrapper<>(); queryWrapper.ge(PlusAccount::getId, 100); queryWrapper.eq(PlusAccount::getEmail, "michael@gmail.com"); Page p = Page.of(page, pageSize, 20000, false); mapper.selectPage(p, queryWrapper); ``` 10 轮的测试结果： ``` --------------- >>>>>>>testFlexPaginate:90 >>>>>>>testPlusPaginate:671 --------------- >>>>>>>testFlexPaginate:78 >>>>>>>testPlusPaginate:643 --------------- >>>>>>>testFlexPaginate:80 >>>>>>>testPlusPaginate:638 --------------- >>>>>>>testFlexPaginate:79 >>>>>>>testPlusPaginate:613 --------------- >>>>>>>testFlexPaginate:75 >>>>>>>testPlusPaginate:627 --------------- >>>>>>>testFlexPaginate:72 >>>>>>>testPlusPaginate:606 --------------- >>>>>>>testFlexPaginate:69 >>>>>>>testPlusPaginate:585 --------------- >>>>>>>testFlexPaginate:70 >>>>>>>testPlusPaginate:589 --------------- >>>>>>>testFlexPaginate:69 >>>>>>>testPlusPaginate:586 --------------- >>>>>>>testFlexPaginate:68 >>>>>>>testPlusPaginate:585 ``` ::: tip 测试结论 Mybatis-Flex 的分页查询速度，大概是 Mybatis-Plus 的 5~10 倍左右。 ::: ## 数据更新 Mybatis-Flex 的代码如下： ```java 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： ```java PlusAccount plusAccount = new PlusAccount(); plusAccount.setUserName("testInsert" + i); plusAccount.setNickname("testInsert" + i);
