# 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:26 >>>>>>>testPlusSelectOneWithLambda:109 >>>>>>>testPlusSelectOne:119 --------------- >>>>>>>testFlexSelectOne:19 >>>>>>>testPlusSelectOneWithLambda:104 >>>>>>>testPlusSelectOne:98 --------------- >>>>>>>testFlexSelectOne:15 >>>>>>>testPlusSelectOneWithLambda:94 >>>>>>>testPlusSelectOne:95 --------------- >>>>>>>testFlexSelectOne:16 >>>>>>>testPlusSelectOneWithLambda:90 >>>>>>>testPlusSelectOne:87 --------------- >>>>>>>testFlexSelectOne:15 >>>>>>>testPlusSelectOneWithLambda:93 >>>>>>>testPlusSelectOne:55 --------------- >>>>>>>testFlexSelectOne:10 >>>>>>>testPlusSelectOneWithLambda:60 >>>>>>>testPlusSelectOne:48 --------------- >>>>>>>testFlexSelectOne:8 >>>>>>>testPlusSelectOneWithLambda:54 >>>>>>>testPlusSelectOne:51 --------------- >>>>>>>testFlexSelectOne:8 >>>>>>>testPlusSelectOneWithLambda:57 >>>>>>>testPlusSelectOne:56 --------------- >>>>>>>testFlexSelectOne:9 >>>>>>>testPlusSelectOneWithLambda:69 >>>>>>>testPlusSelectOne:55 --------------- >>>>>>>testFlexSelectOne:7 >>>>>>>testPlusSelectOneWithLambda:56 >>>>>>>testPlusSelectOne:55 ``` ::: 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： ```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： ``` --------------- >>>>>>>testFlexSelectTop10:12 >>>>>>>testPlusSelectTop10WithLambda:56 >>>>>>>testPlusSelectTop10:53 --------------- >>>>>>>testFlexSelectTop10:10 >>>>>>>testPlusSelectTop10WithLambda:57 >>>>>>>testPlusSelectTop10:56 --------------- >>>>>>>testFlexSelectTop10:9 >>>>>>>testPlusSelectTop10WithLambda:51 >>>>>>>testPlusSelectTop10:47 --------------- >>>>>>>testFlexSelectTop10:9 >>>>>>>testPlusSelectTop10WithLambda:50 >>>>>>>testPlusSelectTop10:48 --------------- >>>>>>>testFlexSelectTop10:8 >>>>>>>testPlusSelectTop10WithLambda:51 >>>>>>>testPlusSelectTop10:47 --------------- >>>>>>>testFlexSelectTop10:9 >>>>>>>testPlusSelectTop10WithLambda:50 >>>>>>>testPlusSelectTop10:47 --------------- >>>>>>>testFlexSelectTop10:8 >>>>>>>testPlusSelectTop10WithLambda:50 >>>>>>>testPlusSelectTop10:49 --------------- >>>>>>>testFlexSelectTop10:7 >>>>>>>testPlusSelectTop10WithLambda:50 >>>>>>>testPlusSelectTop10:47 --------------- >>>>>>>testFlexSelectTop10:6 >>>>>>>testPlusSelectTop10WithLambda:46 >>>>>>>testPlusSelectTop10:49 --------------- >>>>>>>testFlexSelectTop10:8 >>>>>>>testPlusSelectTop10WithLambda:48 >>>>>>>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： ```java 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： ```java LambdaQueryWrapper 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");

mapper.updateByQuery(flexAccount, queryWrapper); ``` Mybatis-Plus 的代码如下： ```java 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");
