其实不难发现，SPI 机制的具体实现本质上还是通过反射完成的。即：**我们按照规定将要暴露对外使用的具体实现类在 `META-INF/services/` 文件下声明。**

另外，SPI 机制在很多框架中都有应用：Spring 框架的基本原理也是类似的方式。还有 Dubbo 框架提供同样的 SPI 扩展机制，只不过 Dubbo 和 spring 框架中的 SPI 机制具体实现方式跟咱们今天学得这个有些细微的区别，不过整体的原理都是一致的，相信大家通过对 JDK 中 SPI 机制的学习，能够一通百通，加深对其他高深框的理解。

通过 SPI 机制能够大大地提高接口设计的灵活性，但是 SPI 机制也存在一些缺点，比如：
