[nkorange]

@ouyangzhiming 你仔细看下我的回复，路径是客户端的日志路径

[kexianjun]

@nkorange I have encountered the same Exception, here is the nameing.log
naming.log

[kexianjun]

知道原因了，似乎是客户端和服务端不匹配引起的 bug

[tianyichenlian]

怎么解决的，大神@kexianjun

[tianyichenlian]

我的客户端用的1.0.0，服务端也是1.0.0，但是多个启动后，nacos维持5秒心跳时，用不了多久，就都会报这个错。刷屏。

[ouyangzhiming]

nacos-all 1.0.0
alibaba cloud ：0.2.2.RELEASE
spring cloud版本：Greenwich.SR1
spring boot版本：2.1.4.RELEASE

[tianyichenlian]

我是nacos-all 1.0.0
alibaba cloud:0.9.0RELEASE
spring cloud:GREENWISH.SR1
spring boot:2.1.2RELEASE，有心跳报错问题 com.alibaba.nacos.api.exception.NacosException: failed to req API:http://127.0.0.1:8848/nacos/v1/ns/instance/list. code:404 msg: service not found: DEFAULT_GROUP@@localhost

[tianyichenlian]

nacos-all 1.0.0
alibaba cloud ：0.2.2.RELEASE
spring cloud版本：Greenwich.SR1
spring boot版本：2.1.4.RELEASE

求救 ，spring cloud多个服务配置nacos后，单独跑一个服务好好的，控制台心跳信息一直正常，再启动一个服务后，开始运行是好的，运行一会后，就会有一个服务出现如下报错：

nacos-all 1.0.0

spring cloud版本：Greenwich.SR1
spring boot版本：2.1.4.RELEASE

还是有这个问题

[kexianjun]

@tianyichenlian

怎么解决的，大神@kexianjun

我使用的是 nacos-discovery-spring-boot-starter 0.2.1 的版本接入的，之所以报 failed to req API:/nacos/v1/ns/instance after all servers，是因为在注册服务实例的时候，cluster 是这么设置的

public void registerService(String serviceName, Instance instance) throws NacosException {

        LogUtils.LOG.info("REGISTER-SERVICE", "registering service " + serviceName + " with instance:" + instance);

        final Map<String, String> params = new HashMap<String, String>(8);
        params.put("tenant", namespace);
        params.put("ip", instance.getIp());
        params.put("port", String.valueOf(instance.getPort()));
        params.put("weight", String.valueOf(instance.getWeight()));
        params.put("healthy", String.valueOf(instance.isHealthy()));
        params.put("metadata", JSON.toJSONString(instance.getMetadata()));
        if (instance.getService() == null) {
            params.put("serviceName", serviceName);
        } else {
            params.put("service", JSON.toJSONString(instance.getService()));
        }
        params.put("cluster", JSON.toJSONString(instance.getCluster()));

        reqAPI(UtilAndComs.NACOS_URL_INSTANCE, params, "PUT");

cluster 设置成了一个 JSON 串，然后服务端校验不通过导致的；我的做法是排除掉 nacos-discovery-spring-boot-starter 0.2.1 里面的 nacos-client，重新导入正确的 client 包

[tianyichenlian]

请问,nacos的接入必须用集群模式么？我是单机模式报那个错，然后就是服务注册，需要自己在client端，也就是自己的服务里写服务注册代码么，您的那个服务注册的类是自己写的么？不写的话，是不是只有服务发现，没有服务注册。目前作为配置中心，nacos我这里是正常的，就是服务注册维持心跳时，一会就报那个错。总会有个DEFAULT-GROUP@localhost类似的服务找不到，然后持续报那个错

[tianyichenlian]

我找到了这个类，我用的是nacos-client1.0.0，代码里已经不是那么写的了。。但是我还是那个错

可以使用单机模式的；服务注册是需要自己调用 nacos 的 api，然后服务发现就调用 api 添加监听器就可以；心跳报错的问题我过后 debug 一下

[tianyichenlian]

我是spring cloud架构的微服务，添加了自动发现服务的注解，nacos里能发现每个服务。那么服务注册还需要自己在每个服务里写代码调用nacos注册么？

[nkorange]

大家的问题如果不是和楼主的一样，请单独建一个issue。
