在idea原有项目上创建新module-MsgSns

File/New/Module

有时spring网站无法访问时，我们可以把https->改为http

image.png module命名为msgsns 选择Eureka Discovery Client

一路next到finsh

如果maven刷新失败，按下面重新刷新

选择pom.xml文件/

Run Dashboard

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

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

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

image.png image.png

可在eureka后台看不到Client的注册实例信息

image.png

pom.xml中添加依赖

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
</dependency>

在此运行msgsns模块

可以看到成功注册上来了

现在原来的项目wechatTask-guns也注册到Eureka服务上（各个服务）

工程的pom.xml文件加入

        <!--Eureka注册与发现的客户端导入-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            <version>2.1.1.RELEASE</version>
        </dependency>

工程的运行类添加注解

@EnableDiscoveryClient

image.png

在application.yml添加注册配置

eureka:
  client:
    service-url:
      #多台Eureka服务用“，”隔开
      defaultZone: http://localhost:8761/eureka/,http://localhost:8762/eureka/,http://localhost:8763/eureka/  

spring:
  application:
    name: wechat_task

运行wechatTask-guns项目

访问

http://localhost:8761/
