config-server的bootstrap.yml的配置如下：

server:port: 9010
spring:application:name: configcloud:config:server:git:#码云的用户名和密码及地址username: **** password: ****uri: https://gitee.com/lijiaxi118/blog-repo
eureka:client:service-url:defaultZone: http://localhost:9001/eureka/

3、SpringCloud Config Client端配置

config-client pom.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.1.2.RELEASE</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.lee.self</groupId><artifactId>user</artifactId><version>0.0.1-SNAPSHOT</version><name>user</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version><spring-cloud.version>Greenwich.SR1</spring-cloud.version></properties><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-config</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-netflix-eureka-client</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-openfeign</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bus-amqp</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!-- 增加swagger ui展示 --><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.4.0</version></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.4.0</version></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-dependencies</artifactId><version>${spring-cloud.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build><repositories><repository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/milestone</url></repository></repositories></project>复制代码

config-client的bootstrap.yml配置:

spring:application:name: usercloud:config:discovery:service-id: configenabled: trueprofile: proeureka:client:service-url:defaultZone: http://localhost:9001/eureka/server:port: 9005
ribbon:eureka:enabled: true复制代码

4、测试

启动注册中心eureka

启动config server 访问localhost:9010/user-dev.yml监测是否启动成功

启动config client

在client项目中写一个测试类如下

测试类如下

@Component
@RefreshScope
@Data
@ConfigurationProperties(prefix = "spring.redis")
public class RedisConfig {private String host;private String port;
}@RestController
@RequestMapping("/test")
public class ConfigController {@Autowiredprivate RedisConfig redisConfig;@RequestMapping("/print")public String print() {return "host:" +"\t" + redisConfig.getHost()+"====Port:"+redisConfig.getPort();}
}复制代码

页面访问http://localhost:9005/test/print,查看结果

修改gitee中的user-dev.yml文件

使用postman的post请求访问http://localhost:9010/actuator/bus-refresh

继续浏览器访问http://localhost:9005/test/print查看结果是否更新

自此config的刷新基本完成，最后一步在gitee中配置webhooks，每一次push修改之后都会自动的通知到各个客户端

4、配置仓库中的webhooks

点击gitee中的管理——》webhooks，填入外网访问的路径即可。
