SpringCloud 项目整合 nacos 出现报错

首先 - - >  检查对应的yml 配置 文件

server:
  port: 8081
spring:
  application:
    name: user-service
  datasource:
    url: jdbc:mysql://localhost:3306/cloud_user?useSSL=false

    driver-class-name: com.mysql.jdbc.Driver
  #Naocs配置

    nacos:
      server-addr: localhost:8848
      config:

      discovery:
        cluster-name: HZ
        namespace: public # 命名空间，填ID
    ribbon:
