# fluent-sql # 前言
不知道大家有没有这样的感觉就笔者而言用了这么多年的Mybatis再怎么说也应该“日久生情”了吧结果可惜啊可惜Mybatis这尊大佛还是让我爱不起来。随着开发水平的提高和对写代码这件事情本身如何更为优雅的深入研究后让早已真正爱上面向对象模式开发的我硬着头皮偶尔得**强制**切换到面向SQL编程属实是令人头秃。这不我这次任性了一回手撸了一个java代码写SQL的东东这就是**Fluent SQL。**
# **这是个啥**
大家肯定很好奇Fluent SQL是个啥咱们先从Fluent来理解。
| fluent | 英[ˈfluːənt] 美[ˈfluːənt] |
| ------ | ------------------------------------------------------------ |
| adj. | (说话)流利的; (文体) 流畅的; (动作、曲线等) 优美自然的; (河水等) 畅流的; |
顾名思义,我们想要写出**”优美自然的SQL“**,同时又想要**流畅地**写出SQL那就快来试试我这个组件吧。组件很轻量级可以非常快速集成项目中可以用于替换mybatis的XML。
作为Java程序员首选是使用Java代码来处理业务而非将大多业务都放在XML里面向SQL编程。都2302年了我们也该寻求点不同的东西了。

## 单表查询
单表查询可以省略结果映射,程序自动使用主表实体进行自动映射
```java
class Test {
public static void main(String[] args) {
// 单表查询所有字段
List<SaasTenant> tenants = select().from(SaasTenant.class).list();
// 单表查询指定字段,条件 年龄小于50
List<SaasTenant> points = select(SaasTenant::getId, SaasTenant::getName).from(SaasTenant.class)
.matching(where(SaasTenant::getAge).lt(50))
.list();
}
}
```
