更轻量

MyBatis-Flex 除了 MyBatis 本身，再无任何第三方依赖，因此会带来更高的自主性、把控性和稳定性。在任何一个系统中，依赖越多，稳定性越差。

更灵活

MyBatis-Flex 提供了非常灵活的 QueryWrapper，支持关联查询、多表查询、多主键、逻辑删除、乐观锁更新、数据填充、数据脱敏等等。

更高的性能

MyBatis-Flex 通过独特的架构，没有任何 MyBatis 拦截器、在 SQL 执行的过程中，没有任何的 SQL Parse，因此会带来指数级的性能增长。

MyBatis-Flex 和同类框架「功能」对比

MyBatis-Flex 主要是和 MyBatis-Plus 与 Fluent-MyBatis 对比，内容来源其官网、git 或者 网络文章，若有错误欢迎纠正。

• MyBatis-Plus：老牌的 MyBatis 增强框架，开源于 2016 年。
• Fluent-MyBatis：阿里云开发的 MyBatis 增强框架（来自于阿里云·云效产品团队）

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);

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：

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);

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：

QueryWrapper queryWrapper = new QueryWrapper()
    .where(FLEX_ACCOUNT.ID.ge(100));
mapper.paginate(page, pageSize, 20000, queryWrapper);

MyBatis-Plus 的代码如下：

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：

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");

使用 MyBatis 原生功能

我们使用 MyBatis-Flex 作为 MyBatis 的增强框架进行代码开发，并不会影响原有的 MyBatis 的任何功能。
