快速集成示例

配置信息服务端

1. pom导入依赖

启动类

@SpringBootApplication
@EnableConfigServer
public class SpringcloudConfigTestApplication {

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

}

2.application.yml配置github远程

#
server:
  port: 5001

#
spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        git:
       # 远程github仓库
          uri: https://github.com/LaiHouWen/temp.git
          username: github 账号
          password: github 密码
# 本地仓库
#          uri: D:\eclipse_workspace\springcloud\springcloud-config-server\src\main\resources\configs

# actuator
#http://localhost:5001/actuator
management:
  endpoints:
    web:
      exposure:
        include: "*"

# 打印log日志
logging:
  level:
    root: warn
    org.springframework.cloud: debug

github远程仓库上的配置文件

客户端

1. pom导入依赖

        <java.version>1.8</java.version>
        <spring-cloud.version>Hoxton.SR8</spring-cloud.version>
    </properties>

                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2.启动类

@SpringBootApplication
@EnableEurekaClient
@EnableDiscoveryClient
public class SpringcloudConfigClientApplication {

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

}

controller请求

@RestController
public class HelloController {

    @GetMapping("/index")
    public Object getIndex(){
        return "获取配置中心的config";
    }

}

3.application.yml 配置类

server:
  port: 8006

bootstrap.yml 拉取配置类

spring:
  cloud:
    config:
    # 建议配置文件名为服务名
      name: hello
      uri: http://localhost:5001/
  profiles:
   #测试环境配置
    active: test
