找到了其中比较关键的一句：ERROR com.alibaba.nacos.common.remote.client.grpc.GrpcClient - Server check fail, please check server localhost,port 9848 is available , error =java.util.concurrent.ExecutionException: com.alibaba.nacos.shaded.io.grpc.StatusRuntimeException: UNAVAILABLE: io exception
大意是：请检查”服务器localhost 端口9848 ，这个服务器不可用“

本地nacos并没有启动，所以这样提示没有问题，但是问题在于为什么会提示服务器是localhost本地，而不是远程服务器，因为有关nacos的配置全都是配置的远程服务器的地址、端口等。

解决：

检查项目配置是否改掉了配置：没有改成远程的nacos的配置。结果发现配置没有问题，因为整个配置的更改都是直接使用Eclipse的替换的。
但是替换有个问题是：只能替换已有的文本，对应默认的配置是没法替换的。
比如，当前这个问题，就是因为spring.cloud.nacos.config的配置信息中没有配置nacos的配置地址spring.cloud.nacos.config.server-addr（采用的默认的本地地址端口localhost:8848）,
只配置了nacos的服务发现的地址，spring.cloud.nacos.discovery.server-addr=47.109.90.76:8848。
所以，一定要显示同时配置出Nacos的服务注册/发现以及配置的地址，如下：

spring.application.name=your-application-name

spring.cloud.nacos.discovery.server-addr=ip:port
spring.cloud.nacos.discovery.enabled=true
spring.cloud.nacos.username=nacos
spring.cloud.nacos.password=your-password

spring.cloud.nacos.config.server-addr=ip:port
spring.cloud.nacos.config.group=your-group-name
spring.cloud.nacos.config.file-extension=properties
spring.cloud.nacos.config.refresh-enabled=true
