Part 4: 在文章中介绍Java SPI提到了“文件的内容为接口的实现类，多个实现类用换行符分隔”， 而在Java SPI 官方文档中的介绍时是这么介绍的：The name of the configuration file is the fully qualified class name of the service provider, in which each component of the name is separated by a period (.), and nested classes are separated by a dollar sign ($).
所以多个类用点隔开，如果是嵌套类则用$隔开。 这里是否有歧义？ （百技268期第四组）
