报错java.net.UnknownHostException: nacos-payment-provider

环境 Springboot3.0.2，SpringCload22.0.0
服务都已经注册到nacos了，但是在使用RestTemplate 调用服务提供者时报错

java.net.UnknownHostException: nacos-payment-provider
	at java.base/sun.nio.ch.NioSocketImpl.connect(NioSocketImpl.java:560) ~[na:na]

这是因为nacos在2021年之前不再默认集成Ribbon，所以需要在调用项目的pom文件中添加依赖
