添加依賴關係的最方便的方法是經過Spring Boot啓動器org.springframework.cloud:spring-cloud-starter-config
。還有一個Maven用戶的父pom和BOM(spring-cloud-starter-parent
)和用於Gradle和Spring CLI用戶的Spring IO版本管理屬性文件。示例Maven配置:git
的pom.xmlgithub
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.3.5.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Brixton.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> <!-- repositories also needed for snapshots and milestones -->
那麼你能夠建立一個標準的Spring Boot應用程序,像這個簡單的HTTP服務器:spring
@SpringBootApplication @RestController public class Application { @RequestMapping("/") public String home() { return "Hello World!"; } public static void main(String[] args) { SpringApplication.run(Application.class, args); } }
當它運行它將從端口8888上的默認本地配置服務器接收外部配置,若是它正在運行。要修改啓動行爲,您可使用bootstrap.properties
(如application.properties
)更改配置服務器的位置,但用於應用程序上下文的引導階段),例如bootstrap
spring.cloud.config.uri: http://myconfigserver.com
引導屬性將在/env
端點中顯示爲高優先級屬性源,例如服務器
$ curl localhost:8080/env { "profiles":[], "configService:https://github.com/spring-cloud-samples/config-repo/bar.properties":{"foo":"bar"}, "servletContextInitParams":{}, "systemProperties":{...}, ... }
(名爲「configService:<遠程存儲庫的URL> / <文件名>」的屬性源包含值爲「bar」的屬性「foo」,是最高優先級)app
