问题暂时没有解决,在此记录一下

看了很多解决方案,加 ribbon:eureka:enabled: true不管用,名称也一致

后来查了一下注册中心,发根本就没有mysql服务,因此问题是出在了服务没有成功注册,那么肯定是配置文件出了问题.配置文件如下:

server:
  port: 2000
spring:
  application:
    name: atguigu-crowd-mysql
  datasource:
    name: mydb
    type: com.alibaba.druid.pool.DruidDataSource
    url: jdbc:mysql://localhost:3306/project_crowd?serverTimezone=UTC&useUnicode=true&characterEncoding=UTF-8
    username: root
    password: root
    driver-class-name: com.mysql.cj.jdbc.Driver
eureka:
  client:
    register-with-eureka: false #  是否将自己注册到Eureka Server上，默认为true 当前服务本身就是注册中心，不必“自己注册自己”
    fetch-registry: false       # 当前服务本身就是注册中心，不必“从注册中心取回信息”
    service-url:
      defaultZone: http://localhost:1000/eureka
mybatis:
  mapper-locations: classpath:/mybatis/mapper/*.xml #匹配对应的xml文件
  type-aliases-package: com.atguigu.crowd.mapper  # 配置对应的映射接口类所在的包
logging:
  level:
    com.atguigu.crowd.mapper: debug
    com.atguigu.crowd.test: debug
ribbon:
  eureka:
    enabled: true

果然,多加了

 register-with-eureka: false #  是否将自己注册到Eureka Server上，默认为true 当前服务本身就是注册中心，不必“自己注册自己”
 fetch-registry: false       # 当前服务本身就是注册中心，不必“从注册中心取回信息”

把这个删除,那么就会把服务注册到注册中心.问题得到解决.
