概述

Spring Cloud實戰(zhàn)-06使用/actuator/bus-refresh端點手動刷新配置 + 使用Spring Cloud Bus自動更新配置 中說到了@RefreshScope實現(xiàn)配置刷新，這里我們來通過一個例子再來感受下。

4個微服務工程：

• Eureka Server ： https://github.com/yangshangwei/springcloud-o2o/tree/master/eureka-server 8762端口
• Artisan Config (Config Server)：https://github.com/yangshangwei/springcloud-o2o/tree/master/artisan_config 9898端口
• Artisan Order (Config Client) ：https://github.com/yangshangwei/springcloud-o2o/tree/master/artisan_order 8081端口
• 配置文件存儲中心： https://github.com/yangshangwei/spring-cloud-config-center/blob/master/artisan-order-dev.yml

配置屬性給artisan-order模塊使用

我們在遠端Git上增加幾個自定義的屬性

通過config server來訪問下 ，確保能正常訪問

http://localhost:9898/artisan-order-dev.yml

---

配置文件

@ConfigurationProperties 參考之前的博客： Spring Boot2.x-03Spring Boot基礎-基于properties的類型安全的配置

---

注解說明 見注釋

package com.artisan.order.config;import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.cloud.context.config.annotation.RefreshScope; import org.springframework.stereotype.Component;@Data @Component //@ConfigurationProperties：告訴springboot將本類中所有屬性和配置文件中相關的配置進行綁定； // prefix="customized"：指出將配置文件中customized下的所有屬性進行一一映射 @ConfigurationProperties(prefix = "customized") // 需要動態(tài)刷新配置，加上該注解 @RefreshScope public class CustomizedConfig {private String apiUrl;private String apiCode; }

測試下

package com.artisan.order.controller;import com.artisan.order.config.CustomizedConfig; import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController;@RestController @Slf4j public class CustomizedController {@Autowiredprivate CustomizedConfig customizedConfig;@GetMapping("/customizedPro")public String getCustomizedProperties(){String apiUrl = customizedConfig.getApiUrl();String apiCode = customizedConfig.getApiCode();log.info("apiUrl:{}, apiCode:{}",apiUrl,apiCode);return "apiUrl:" + apiUrl + " , apiCode:" + apiCode;} }

啟動服務，訪問 http://localhost:8081/customizedPro

將遠端的配置修改下

再次訪問 http://localhost:8081/customizedPro

還是沒變。。。。

接下來通過curl POST手工刷新下吧，或者在git上設置webhooks 自動更新

---

使用curl 手工刷新配置

curl -v -X POST http://localhost:9898/actuator/bus-refresh

無需重啟，再次訪問 http://localhost:8081/customizedPro

至此，通過@RefreshScope+手工刷新的方式實現(xiàn)了無需重啟應用刷新配置的功能。

通過RabbitMQ實現(xiàn)自動刷新請移步我的另外一篇博客：Spring Cloud實戰(zhàn)-06使用/actuator/bus-refresh端點手動刷新配置 + 使用Spring Cloud Bus自動更新配置
