Spring|Spring Cloud基础之Config Server配置中心简单搭建 SpringCloud基础之ConfigServer配置中

首先需要在Discovery Service章节中的创建Discovery Server服务
创建Config Server服务

//导入包，实际是通过Spring Initializr导入的，Eureka Discovery,Config Server,Actuactor spring-cloud-config-server spring-cloud-starter-netflix-eureka-server spring-boot-starter-actuator //配置启动类注解EnableConfigServer @SpringBootApplication @EnableConfigServer @EnableDiscoveryClient public class ConfigServerApplication { public static void main(String[] args) { SpringApplication.run(ConfigServerApplication.class, args); } } //配置文件 server.port=8888 spring.cloud.config.server.git.uri=https://github.com/bu6030/scf-config-repository.git spring.application.name=config-server eureka.client.service-url.defaultZone=http://localhost:8761/eureka

启动时需要默认的SpringCloudserver已经启动
通过url可以找到对应的配置内容

//配置的Endpoint规则几种方式 GET /{application}/{profile}[/{label}] /myap/dev/master,/myapp/prod/v2,/myapp/default GET /{application}-{profile}.(yml | properties) /myapp-dev.yml,/myapp-prod.properties,/myapp-default.properties GET /{label}-{application}-{profile}.(yml | properties) /master/myapp-dev.yml,/v2/myapp-prod.properties,/master/myapp-default.properties//http://localhost:8888/config-client-app.yml返回内容： some: other: property: global property: app specific overridden value //http://localhost:8888/config-client-app.properties返回内容 some.other.property: global some.property: app specific overridden value //http://localhost:8888/config-client-app/prod返回内容 { "name": "config-client-app", "profiles": [ "prod" ], "label": null, "version": "1cb37c9ba1fa4c17d2ae7489c2e592eba1688547", "state": null, "propertySources": [ { "name": "https://github.com/bu6030/scf-config-repository.git/config-client-app-prod.properties", "source": { "some.property": "profile specific value", "some.other.property": "profile specific value" } }, { "name": "https://github.com/bu6030/scf-config-repository.git/config-client-app.properties", "source": { "some.property": "app specific overridden value" } }, { "name": "https://github.com/bu6030/scf-config-repository.git/application.properties", "source": { "some.property": "global", "some.other.property": "global" } } ] } //http://localhost:8888/config-client-app/default返回内容 { "name": "config-client-app", "profiles": [ "default" ], "label": null, "version": "1cb37c9ba1fa4c17d2ae7489c2e592eba1688547", "state": null, "propertySources": [ { "name": "https://github.com/bu6030/scf-config-repository.git/config-client-app.properties", "source": { "some.property": "app specific overridden value" } }, { "name": "https://github.com/bu6030/scf-config-repository.git/application.properties", "source": { "some.property": "global", "some.other.property": "global" } } ] }

配置config client

//导入包，实际是通过Spring Initializr导入的，Eureka Discovery,Config Client,Actuactor sspring-cloud-starter-config spring-cloud-starter-netflix-eureka-client spring-boot-starter-actuator //配置启动类注解EnableConfigServer @SpringBootApplication @EnableDiscoveryClient @RestController public class ConfigClientAppApplication { @Autowired private ConfigClientAppConfiguration properties; @Value("${some.other.property}") private String someOtherPorperty; public static void main(String[] args) { SpringApplication.run(ConfigClientAppApplication.class, args); } @RequestMapping("/") public String printConfig(){ StringBuffer sb = new StringBuffer(); sb.append(properties.getProperty()); sb.append(" || "); sb.append(someOtherPorperty); return sb.toString(); } } @Component @ConfigurationProperties(prefix="some") public class ConfigClientAppConfiguration { private String property; public String getProperty() { return property; } public void setProperty(String property) { this.property = property; } } //配置文件 server.port=8080 spring.application.name=config-client-app spring.cloud.config.discovery.enabled=true eureka.client.service-url.defaultZone=http://localhost:8761/eureka

【Spring|Spring Cloud基础之Config Server配置中心简单搭建】修改配置文件后自动刷新通过调用http://localhost:8080/actuato...刷新接口
配置文件需要增加

management.endpoints.enabled-by-default=true management.endpoints.web.exposure.include=refresh,health,bus-refresh //启动类增加RefreshScope后，@Value也可以刷新 @SpringBootApplication @EnableDiscoveryClient @RestController @RefreshScope public class ConfigClientAppApplication { @Autowired private ConfigClientAppConfiguration properties; @Value("${some.other.property}") private String someOtherPorperty; public static void main(String[] args) { SpringApplication.run(ConfigClientAppApplication.class, args); } @RequestMapping("/") public String printConfig(){ StringBuffer sb = new StringBuffer(); sb.append(properties.getProperty()); sb.append(" || "); sb.append(someOtherPorperty); return sb.toString(); } } //刷新服务的方式， http://localhost:8080/actuator/refresh http://localhost:8080/actuator/bus-refresh
