三.发布配置

四.查看”配置列表”

五.编码阶段

1.pom

</project>

2.配置文件（ bootstrap.properties）

这里是配置文件必须使用 bootstrap.properties， bootstrap.properties与application.yml的不同，后期有教程会补上。

spring.application.name=nacos-config-client
server.port=8003
spring.cloud.nacos.config.server-addr=127.0.0.1:8848

3.启动主类（NacosConfig8003）

@SpringBootApplication
public class NacosConfig8003 {
    public static void main(String[] args) {
        SpringApplication.run(NacosConfig8003.class, args);
    }
}

4.测试文件（TestConfigController）

@RestController
@RefreshScope//声明刷新域
public class TestConfigController {

    @Value("${client.user.name}")
    private String name;
    @Value("${client.user.phone}")
    private String phone;

    @GetMapping("/test")
    public String test() {
        return "name:"+name+" phone:"+phone;
    }

}

5.启动

trationDelegate$BeanPostProcessorChecker : Bean 'configurationPropertiesRebinderAutoConfiguration' of type [org.springframework.cloud.autoconfigure.ConfigurationPropertiesRebinderAutoConfiguration$$EnhancerBySpringCGLIB$$f3138e36] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying) 
o.s.c.a.n.c.NacosPropertySourceBuilder   : Loading nacos data, dataId: 'nacos-config-client.properties', group: 'DEFAULT_GROUP'

启动日志中有这两句。说明配置成功。
