# 基于 Kotlin 扩展 Mybatis-Flex
|
||||
## 快速开始
|
||||
|
||||
在开始之前，我们假定您已经：
|
||||
|
||||
- 熟悉 Kotlin 环境配置及其开发
|
||||
- 熟悉 关系型 数据库，比如 MySQL
|
||||
- 熟悉 Kotlin 构建工具，比如 Gradle、Maven
|
||||
|
||||
> 当前章节涉及到的 [演示源码](https://gitee.com/mybatis-flex/mybatis-flex/tree/main/mybatis-flex-test/mybatis-flex-spring-kotlin-test) 已经全部上传
|
||||
>
|
||||
> 在开始之前，您也可以先下载到本地，导入到 idea 开发工具后，在继续看文档。
|
||||
|
||||
|
||||
## 特点
|
||||
|
||||
- 本模块基于 Mybatis-Flex 核心库 ，只做扩展不做改变
|
||||
- 结合 Kotlin 特性、DSL让数据库操作更简单
|
||||
|
||||
## Hello World 文档
|
||||
|
||||
**第 1 步：创建 Kotlin 项目，并添加 Kotlin 的扩展依赖**
|
||||
|
||||
>如何创建 Kotlin 项目可参考 [官方文档](https://www.kotlincn.net/docs/tutorials/jvm-get-started.html)
|
||||
|
||||
需要添加的主要依赖：
|
||||
|
||||
**【Kotlin】**
|
||||
|
||||
```kotlin
|
||||
dependencies {
|
||||
implementation("com.mybatis-flex:mybatis-flex-kotlin:1.5.7")
|
||||
compileOnly("com.mybatis-flex:mybatis-flex-processor:1.5.7")
|
||||
}
|
||||
```
|
||||
|
||||
**【Maven】**
|
||||
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>com.mybatis-flex</groupId>
|
||||
<artifactId>mybatis-flex-kotlin</artifactId>
|
||||
<version>${mybatis-flex.version}</version>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
**第 2 步：创建数据库表与配置数据源**
|
||||
|
||||
> 请参考 [快速开始](../intro/getting-started.md) 创建数据库表与配置数据源，
|
||||
> 或者使用演示源码中的内嵌数据库快速体验
|
||||
|
||||
**第 3 步：编写实体类**
|
||||
|
||||
```kotlin
|
||||
@Table("tb_account")
|
||||
class Account {
|
||||
|
||||
@Id
|
||||
var id: Long
|
||||
var userName: String
|
||||
var age: Integer
|
||||
var birthday: Date
|
||||
|
||||
}
|
||||
```
|
||||
|
||||
- 使用 `@Table("tb_account")` 设置实体类与表名的映射关系
|
||||
- 使用 `@Id` 标识主键
|
||||
|
||||
**第 4 步：开始使用**
|
||||
|
||||
添加测试类，进行功能测试：
|
||||
|
||||
```kotlin
|
||||
fun main() {
|
||||
//加载数据源(为了方便演示这里使用了演示源码中的内嵌数据源)
|
||||
val dataSource: DataSource = EmbeddedDatabaseBuilder()
|
||||
.setType(EmbeddedDatabaseType.H2)
|
||||
.addScript("schema.sql")
|
||||
.addScript("data-kt.sql")
|
||||
.build()
|
||||
//启动并配入数据源
|
||||
buildBootstrap { +dataSource }.start()
|
||||
//条件过滤查询并打印
|
||||
filter<Account> {
|
||||
ACCOUNT.ID `=` 1 and
|
||||
(ACCOUNT.AGE `in` listOf(18,19) or (ACCOUNT.BIRTHDAY between ("2020-01-10" to "2020-01-12")) )
|
||||
}.forEach(::println)
|
||||
//查询全部数据并打印
|
||||
//ACCOUNT.all<Account>().forEach(::println)
|
||||
}
|
||||
```
|
||||
执行的SQL：
|
||||
```sql
|
||||
SELECT * FROM `tb_account` WHERE`id` = 1 AND (`age` IN (18, 19) OR `birthday`BETWEEN '2020-01-10' AND '2020-01-12' )
|
||||
```
|
||||
控制台输出：
|
||||
|
||||
```txt
|
||||
Account(id=1, userName=张三, age=18, birthday=Sat Jan 11 00:00:00 CST 2020)
|
||||
```
|
||||
|
||||
> 以上的示例中， `ACCOUNT` 为 MyBatis-Flex 通过 APT
|
||||
> 自动生成，只需通过静态导入即可，无需手动编码。更多查看 [在Kotlin中使用注解处理器](../others/kapt.md)
|
||||
>
|
||||
> 若觉得 APT 使用不习惯，也可以使用代码生成器来生成。点击 [代码生成器文档](../others/codegen.md) 了解。
|
||||
|
||||
## 更多使用
|
||||
|
||||
- 功能 1：[Bootstrap简化配置]()
|
||||
- 功能 2：[简单查询]()
|
||||
- 功能 3：[表实体扩展]()
|
||||
- 功能 4：[SQL扩展/中缀]()
|
||||
- 功能 5：[Mapper扩展]()
