在分佈式系統中,因爲服務數量巨多,爲了方便服務配置文件統一管理,實時更新,因此須要分佈式配置中心組件。在Spring Cloud中,有分佈式配置中心組件spring cloud config ,它支持配置服務放在配置服務的內存中(即本地),也支持放在遠程Git倉庫中。在spring cloud config 組件中,分兩個角色,一是config server,二是config client。html
建立一個spring-boot項目,取名爲config-server,其pom.xml:java

在程序的入口Application類加上@EnableConfigServer註解開啓配置服務器的功能,代碼以下:git

@SpringBootApplication
@EnableConfigServer
public
class
ConfigServerApplication {

void
main(String[] args) {
SpringApplication.run(ConfigServerApplication.
class
, args);
}
}

須要在程序的配置文件application.properties文件配置如下:github

若是Git倉庫爲公開倉庫,能夠不填寫用戶名和密碼,若是是私有倉庫須要填寫,本例子是公開倉庫,放心使用。spring
遠程倉庫github.com/forezp/Spri… 中有個文件config-client-dev.properties文件中有一個屬性:apache

foo = foo version

啓動程序:訪問http://localhost:8888/foo/dev服務器
