創建微服務項目並註冊到consul

1、生成springboot項目

    方式1：使用idea的"File"->"New"->"Project"方式創建

    方式2：去https://start.spring.io/網站生成項目，然後導入到本地

2、springboot項目添加相關依賴

附上spring-cloud和spring-boot版本對應關係

 

3、修改application.yml內容

完整application.yml文件內容

 

server:

  port: 8080

spring:

  application:

    name: my-user

  cloud:

    consul:

      host: 192.168.47.6

      port: 8500

      discovery:

        service-name: ${spring.application.name}

        acl-token: 6fe90451-ede1-18b7-d3b9-e43ae74c7d51//由於consul配置了acl，所以微服務需要攜帶token進行服務註冊

4、啓動springboot項目

查看consul的ui

 

 

發現"my-user"已經註冊，但是並不完美，它的Tags有紅色的叉叉並且"secure=false"，這是因爲consul是有健康檢查的，接下來解決該問題

5、微服務啓用健康檢查

pom.xml中添加依賴

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-actuator</artifactId>

</dependency>

完整application.yml文件內容

server:

  port: 8080

spring:

  application:

    name: my-user

  cloud:

    consul:

      host: 192.168.47.6

      port: 8500

      discovery:

        service-name: ${spring.application.name}

        acl-token: 6fe90451-ede1-18b7-d3b9-e43ae74c7d51

        health-check-path: /actuator/health

然後再啓動springboot項目即可
