概述
Spring Cloud实战-06使用/actuator/bus-refresh端点手动刷新配置 + 使用Spring Cloud Bus自动更新配置 中说到了@RefreshScope实现配置刷新，这里我们来通过一个例子再来感受下。
4个微服务工程：
- 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
- 配置文件存储中心： https://github.com/yangshangwei/spring-cloud-config-center/blob/master/artisan-order-dev.yml
配置属性给artisan-order模块使用
我们在远端Git上增加几个自定义的属性
通过config server来访问下 ，确保能正常访问
http://localhost:9898/artisan-order-dev.yml
配置文件
@ConfigurationProperties 参考之前的博客： Spring Boot2.x-03Spring Boot基础-基于properties的类型安全的配置
注解说明 见注释
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：告诉springboot将本类中所有属性和配置文件中相关的配置进行绑定；
// prefix="customized"：指出将配置文件中customized下的所有属性进行一一映射
@ConfigurationProperties(prefix = "customized")
// 需要动态刷新配置，加上该注解
@RefreshScope
public class CustomizedConfig {
private String apiUrl;
private String apiCode;
}
测试下
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 {
@Autowired
private 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;
}
}
启动服务，访问 http://localhost:8081/customizedPro
将远端的配置修改下
再次访问 http://localhost:8081/customizedPro
还是没变。。。。
接下来通过curl POST手工刷新下吧，或者在git上设置webhooks 自动更新
使用curl 手工刷新配置
curl -v -X POST http://localhost:9898/actuator/bus-refresh
