Java springboot B2B2C o2o多用戶商城 springcloud架構 (六)分佈式配置中心(Spring Cloud Config)

1、簡介

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

2、構建Config Server

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 {
public static 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

spring.application.name=config-server
server.port= 8888
spring.cloud.config.server.git.uri=https: //github.com/forezp/SpringcloudConfig/
spring.cloud.config.server.git.searchPaths=respo
spring.cloud.config.label=master
spring.cloud.config.server.git.username=your username
spring.cloud.config.server.git.password=your password

  

  • spring.cloud.config.server.git.uri:配置git倉庫地址
  • spring.cloud.config.server.git.searchPaths:配置倉庫路徑
  • spring.cloud.config.label:配置倉庫的分支
  • spring.cloud.config.server.git.username:訪問git倉庫的用戶名
  • spring.cloud.config.server.git.password:訪問git倉庫的用戶密碼

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

1
foo = foo version 3

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

{ "name" : "foo" , "profiles" :[ "dev" ], "label" : "master" ,
"version" : "792ffc77c03f4b138d28e89b576900ac5e01a44b" , "state" : null , "propertySources" :[]}

  架構代碼以下:架構
