注：本文篇幅有点长，所以建议各位下载源码学习。（如需要请收藏！转载请声明来源，谢谢！）

代码下载：https://gitee.com/hong99/spring/issues/I1N1DF

继上文：spring整合各种服务注册中心(zk、eureka、nacos、consul)

nacos相关配置可参考配置中心：

spring的整合分布式配置中心(ACM diamond nacos Apollo)-nacos

注意：基于原有项目请参照：spring整合各种配置中心

注意这里的端口8848与服务的端口一致！

#端口
server.port=8081
#dataId
dataId=hong
#nacos配置
nacos.config.server-addr=127.0.0.1:8848
#host
nacos.config.host=127.0.0.1
#服务名称
spring.application.name=hong-provide-service
#nacos注册
nacos.discovery.server-addr=127.0.0.1:8848

@SpringBootApplication(scanBasePackages = "com.hong.springboot")
@NacosPropertySource(dataId = "hong", autoRefreshed = true,first = true)
@EnableNacosConfig(globalProperties = @NacosProperties(serverAddr = "127.0.0.1:8848"))
public class Application  implements CommandLineRunner {

    @NacosInjected
    private NamingService namingService;

    @Value("${spring.application.name}")
    private String applicationName;

    @Value("${server.port}")
    private Integer serverPort;


    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }

    @Override
    public void run(String... args) throws Exception {
        // 通过Naming服务注册实例到注册中心
        namingService.registerInstance(applicationName, "127.0.0.1", serverPort);
    }
}

结果

总结：注意要区分开 springmvc、springboot、spring cloud都是不同的集成方式，这里没有用到springcloud看了好多文章spring boot都是直接用spring cloud方式去集成，当然也可以，但是要区分开来....，总体来说nacos非常容易上手和功能及文档强大，并且可以作注册和配置中心给力！

注意了：目前HASHICORP禁止了VAULT在中国使用，所以使用国外的注册中心存在一定风险~！

请注意，中国出口管控条例禁止HASHICORP 在中华人民共和国境内销售或以其他方式提供企业版VAULT。鉴于此原因，未经HASHICORP 的书面同意，不得在中华人民共和国境内使用、部署或安装HASHICORP 的VAULT 企业版本软件。

各个注册中心对比

参考：

最后

不管是zk、nacos、consul或者是其他，当然因为注册中心实在有太多了，但都大同小异所以，只实现几种，但是需要用后更需要了解具体解决业务和场景的考虑，而不是单纯为了用工具...，类似zk基于cp，而nacos是基于ap，之间的区别与场景。还有一点需要考虑的是虽然现在技术没有国界，但是随着贸易摩擦目前使用的开源产品很可能随时闭源或停更，还是用国产，因为基于维护升级及安全的考虑，以及更容易上手，并且在性能及相关社区都非常活跃，当然注册中心大部分场景是基于rpc框架结合使用比如dubbo，后续会继续更新，请关注留意。
