本质是报错2022-06-09 22:07:27.934 ERROR 15656c.a.cloud.nacos.NacosConfigProperties : create config service error!properties=NacosConfigProperties{serverAddr=‘null’, encode=‘null’, group=‘DEFAULT_GROUP’, prefix=‘null’, fileExtension=‘properties’, timeout=3000, endpoint=‘null’, namespace=‘null’, accessKey=‘null’, secretKey=‘null’, contextPath=‘null’, clusterName=‘null’, name=‘null’, sharedDataids=‘null’, refreshableDataids=‘null’, extConfig=null},e=,
即无法从配置文件中获取参数，或者说没有配置文件

原因

这是因为开启了nacos的配置中心依赖，此时nacos会从bootstrap中获取配置服务的信息，所以此时的报错并不是针对服务发现的配置错误，而是配置中心没有配置信息的错误

springcloud配置nacos启动报错

错误2

此时配置了bootstrap配置文件和依赖，但是不知道为什么已经报错，无法正常识别配置，只能配合ymal来使用

只从配置文件中获取到了服务节点名字，但是nacos服务地址不知道，所以找不到服务，导致[CLIENT-BEAT] failed to send beat: {“cluster”:“DEFAULT”,“ip”:“172.17.120.213”,“metadata”:{“preserved.register.source”:“SPRING_CLOUD”},“period”:5000,“port”:8005,“scheduled”:false,“serviceName”:“DEFAULT_GROUP@@aimermall-member”,“stopped”:false,“weight”:1.0}心跳验证失败

springcloud配置nacos启动报错
此时的错误是由于服务发现的配置出错，没有找到服务发现的配置中心，需要在application.yml配置服务发现的信息

总结

nacos的配置文件分为配置中心和服务发现两种配置信息，bootstrap.properties
application.yml分别是配置中心和服务发现的配置信息，标准填写为：

服务发现配置

在 application.properties’中配置 Nacos server 的地址：

server.port=8070
spring.application.name=service-provider

spring.cloud.nacos.discovery.server-addr=127.0.0.1:8848

配置中心配置

在 bootstrap.properties 中配置 Nacos server 的地址和应用名
spring.cloud.nacos.config.server-addr=127.0.0.1:8848

spring.application.name=example
