启动类

@EnableConfigServer @SpringBootApplication public class ConfigServer { public static void main(String[] args) { SpringApplication.run(ConfigServer.class, args); } }

properties

spring.application.name=config-server server.port=8767 spring.cloud.config.server.git.uri=https://github.com/roncoo-eshop/roncoo-eshop-config spring.cloud.config.server.git.searchPaths=config-file spring.cloud.config.label=master spring.cloud.config.server.git.username=roncoo-eshop spring.cloud.config.server.git.password=roncoo123456

其实config服务器配置好了是能直接访问的 http://localhost:8767/defaultName/dev 其中defaultName是我们在git上properties中配的defaultName = leo这个字段

然后 修改需要统一配置的服务，加上config客户端依赖

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency>

给yml加上，8767是我们config服务器

spring.application.name=config-client spring.cloud.config.label=master spring.cloud.config.profile=dev spring.cloud.config.uri= http://localhost:8767/ server.port=8764 eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/ feign.hystrix.enabled=true

此时的情况是：只要在git上config-file文件夹下的properties，config-server都会加载，然后我们在项目中不用写任何properties，直接在项目中@Value就可以和写了properties取得一样的效果，只是这个值是从git上取得的。 使用config的好处是项目要改properties，比如dev改pro，不用重启项目了，直接改git，git一改，项目读取的就是git，也自动跟着改了。
