简述
偶然看到一篇关于阿里新orm框架的文章,好奇的点了进去。开发后端多年,看到这个还是有点兴奋的。常用mysql的orm框架mybatis、jpa,到后来的优化框架mybatis-plus都是用过,他们或多或少都有优缺点吧。程序员本就是日常革新技术的职业,所以了解更多的框架绝对不会有错误。所以我尝试着把自己学习该框架的过程,记录下来,尽可能去掉一些项目工程中用不到的功能,展示一些实用有帮助的代码。
特性
首先分享一下码云上的项目链接:码云地址
看一下官方给出的特性图
给出对几个特性乍一看还是很全面的,其中比较吸引我的是两点。
1、从图中给出的语法,和sql十分相近,不仔细看还以为是直接sql语句扔了上来。看上去就比较实用。
2、No xml&mapper,虽然mybatis-plus已经做到实用 IService接口实现大部分的sql操作
项目搭建
springboot搭建一项目的过程就不过多赘述了,这里说下我实用的springboot版本
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.5.5</version> <relativePath/> <!-- lookup parent from repository --> </parent>
代码结构如下:
maven依赖引入-fluent-mybatis
<properties> <fluent-mybatis.version>1.8.7</fluent-mybatis.version> </properties> <dependencies> <!-- 引入fluent-mybatis 运行依赖包, scope为compile --> <dependency> <groupId>com.github.atool</groupId> <artifactId>fluent-mybatis</artifactId> <version>${fluent-mybatis.version}</version> </dependency> <!-- 引入fluent-mybatis-processor, scope设置为provider 编译需要,运行时不需要 --> <dependency> <groupId>com.github.atool</groupId> <artifactId>fluent-mybatis-processor</artifactId> <scope>provided</scope> <version>${fluent-mybatis.version}</version> </dependency> </dependencies>
完整maven依赖如下
