# 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);
|
|
```
|
|
|
|

|
## 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);
|
|
```

## 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<PlusAccount> queryWrapper = new LambdaQueryWrapper<>();
|
|
queryWrapper.ge(PlusAccount::getId, 100);
|
|
queryWrapper.eq(PlusAccount::getEmail, "michael@gmail.com");
|
|
Page<PlusAccount> p = Page.of(page, pageSize, 20000, false);
|
|
mapper.selectPage(p, queryWrapper);
|
|
```
|
|

## 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);
|
|
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);
