问题2

Failed to read artifact descriptor for org.springframework.cloud:spring-cloud-starter-netflix-eureka-client:jar:2.1.2.RELEASE

到moven仓库查看版本https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-netflix-eureka-client

启动类添加注解

@EnableDiscoveryClient

application.properties改为application.yml格式

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/ #注意在：后面一定要有个空格，否则让你怀疑人生
spring:
  application:
    name: wechatMsgSns

运行eurekaService注册中心模块，并访问

http://localhost:8761/

运行msgSns模块

日志打印可看到是注册上去了

可在eureka后台看不到Client的注册实例信息

pom.xml中添加依赖

   org.springframework.boot
   spring-boot-starter-web

在此运行msgsns模块

可以看到成功注册上来了
