springcloud20---Config加入eureka

Config server也可以加用户名和密码。Config client通过用户名和密码访问。

Config server也可以做成高可用集群。

Config与eureka配置使用。把Config server注册到eureka。Config client也要注册到eureka。

配置属性加解密：

配置在git仓库里面是明文，

下载jce8 :

http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

下载之后解压：

里面是2个加解密的策略文件。用这2个策略文件替换jdk里面的策略文件就可以了。
