新建pojo

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.stereotype.Component;
import lombok.Data;
@ConfigurationProperties("jacky.info")
@RefreshScope
@Component
@Data
public class MyProperties {
    int age;
}

新建启动测试类：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
@EnableDiscoveryClient
@RestController
public class NacosProviderApplication {
    public static void main(String[] args) {
        SpringApplication.run(NacosProviderApplication.class, args);
    }
    @Autowired
    private MyProperties myProperties;
    @RequestMapping("test/{id}")
    public String test(@PathVariable Integer id) {
        return "服务提供者 test - id = " + id + " >>> " + myProperties.getAge();
    }
}

nacos页面端新建配置信息：
