3.3.修改yml😶‍🌫️😶‍🌫️😶‍🌫️

在配置文件之前，先配置好自己的gitee或github

server:
  port: 3344

spring:
  application:
    name:  cloud-config-center
  cloud:
    config:
      server:
        git:
          #gitee上面的仓库地址
          uri: git@gitee.com:hqdmdxz/springcould-config.git
          #搜索目录
          search-paths:
            - sprongcloud-config
          #gitee的账号
          username: 账号
          #gitee的密码
          password: 密码
      #读取分支
      lable: master

#注册到eureka
eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka

3.4.主启动类😶‍🌫️😶‍🌫️😶‍🌫️

@SpringBootApplication
@EnableConfigServer
public class ConfigCenterMain3344 {
    public static void main(String[] args) {
        SpringApplication.run(ConfigCenterMain3344.class);
    }
}

3.5.配置类😶‍🌫️😶‍🌫️😶‍🌫️

因为spring-cloud-config-server还不支持github较新的rsa加密方法

@Configuration
public class MyConfig {
    //Shim to fix the way jGit configures JSch
    static {
        JSch.setConfig("signature.rsa", "com.jcraft.jsch.jce.SignatureRSA");
    }
}

4.1.创建工程😶‍🌫️😶‍🌫️😶‍🌫️

• 1.在父工程下创建

    </dependencies>

4.3.修改yml😶‍🌫️😶‍🌫️😶‍🌫️

server:
  port: 3355
spring:
  application:
    name: config-client
  cloud:
    #客户端配置
    config:
      #分支名称
      label: master
      #配置文件名称
      name: config
      #读取后缀名称
      profile: dev
      #配置中心地址
      uri: http://localhost:3344

#服务注册到eureka
eureka:
  client:
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka,http://eureka7002.com:7002/eureka,http://eureka7003.com:7003/eureka

4.4.主启动类😶‍🌫️😶‍🌫️😶‍🌫️

@SpringBootApplication
@EnableEurekaClient
public class ConfigClientMain3355 {
    public static void main(String[] args) {
        SpringApplication.run(ConfigClientMain3355.class);
    }
}

4.5测试😶‍🌫️😶‍🌫️😶‍🌫️

• 1.启动主程序类
• 2.浏览器访问

5.动态刷新 😶‍🌫️😶‍🌫️😶‍🌫️

5.1.修改3355模块😶‍🌫️😶‍🌫️😶‍🌫️

添加依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

5.2.修改yml😶‍🌫️😶‍🌫️😶‍🌫️

暴露监控端点

#暴露监控端点
management:
  endpoints:
    web:
      exposure:
        include: "*"

5.3.修改业务类 😶‍🌫️😶‍🌫️😶‍🌫️

在业务类上面添加@RefreshScope注解

@RestController
@RefreshScope
public class ConfigClientController {
    @Value("${config.info}")
    private String configInfo;

    @GetMapping("/configInfo")
    public String getConfigInfo(){
        return configInfo;
    }
}

5.4.发送POST刷新😶‍🌫️😶‍🌫️😶‍🌫️

• 在修改内容之后，手动刷新客户端

curl -X POST "http://localhost:3355/actuator/refresh"
