Spring Cloud Netflix 文档 中只提到了一部分主要的配置。这篇文章的主要内容就是列出全部的配置项目。
Eureka Client
Eureka Client的配置分为两部分，client的配置和Instance的配置，可以分别在EurekaClientConfigBean和EurekaInstanceConfigBean这两个ConfigBean中查看所有的配置项。这两个类在spring-cloud-netflix-eureka-client模块里，在spring-cloud-netflix-eureka-client.jar文件中。
在spring-cloud-netflix-eureka-client.jar的META-INF文件夹下，有一个spring-configuration-metadata.json文件，这个文件列出来此模块所有的配置项的名称，数据类型，默认值等信息，文件全部内容如下：

}Eureka Server
Eureka Server包含三部分配置，eureka.instance.registry、eureka.dashboard和eureka.server。这三个配置对应的配置属性类分别是InstanceRegistryProperties、EurekaDashboardProperties、EurekaServerConfigBean。这三个类在spring-cloud-netflix-eureka-server模块中，spring-cloud-netflix-eureka-client.jar文件里。同时在此Jar包下的META-INF文件夹下，同样也有一个spring-configuration-meta.json文件，内容如下：

}总结
Spring Cloud的文档简洁明了，短小精悍，学习过程大部分信息都要通过阅读源码来获取。如上，大家可以通过属性配置类文件或者配置元数据文件来获取全面的信息。
