springcloud~配置中心实例搭建

server端

build.gradle相关

dependencies {

    compile('org.springframework.cloud:spring-cloud-config-server',

            'org.springframework.cloud:spring-cloud-starter-netflix-eureka-server'

    )

    testCompile('org.springframework.boot:spring-boot-starter-test')

}

dependencyManagement {

    imports {

        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"

    }

}

bootstrap.yml配置

server:

  port: 8200

spring:

  application:

    name: lind-config-server

  cloud:

    config:

      server:

        git:

          uri: https://github.com/bfyxzls/lindconfig.repo.git/

          search-paths: config-repo

          username: bfyxzls@sina.com

          password: xxxx

启动项相关

@EnableDiscoveryClient

@EnableConfigServer

@SpringBootApplication

class Application {

  public static void main(String[] args) {

    // demo http://localhost://8200/email-svt.yml

    SpringApplication.run(Application.class, args);

  }

}

客户端

build.gradle相关

dependencies {

    compile('org.springframework.boot:spring-boot-starter-web',

            'org.springframework.cloud:spring-cloud-starter-config',

            'org.springframework.cloud:spring-cloud-starter-netflix-eureka-server')

    testCompile('org.springframework.boot:spring-boot-starter-test')

}

dependencyManagement {

    imports {

        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"

    }

}

bootstrap.yml配置

spring:

  application:

    name: lind

  cloud:

    config:

      uri: http://localhost:8200

      profile: svt

      label: master #当 ConfigServer 的后端存储的是 Git 的时候，默认就是 master

eureka:

  client:

    serviceUrl:

      defaultZone: http://localhost:8761/eureka/

启动项相关

@EnableEurekaClient

@SpringBootApplication

public class Application {

  public static void main(String[] args) {

    SpringApplication.run(Application.class, args);

  }

}

@RestController

public class HomeController {

  @Autowired

  private Environment profile;

  @RequestMapping("/")

  public String index(@RequestParam String key) {

    return key + "=" + profile.getProperty(key);

  }

}

配置文件仓库

这是一个GIT仓库，主要存储我们的配置文件的，以application.name作为文件名，profile作为后缀，我们客户端就是某个应用程序，它以后从仓库获取配置信息。

程序配置例子

lind.yml 默认的配置

lind.svt.yml 测试环境配置，将集成默认配置

lind.production.yml 生成环境配置，将集成默认配置
