1 整体规划

1.1 拓扑架构

1.2 基础设置

1.3 相关组件

2 JHipster Registry定制

2.1 下载源码

Github上下载jhipster-jhipster源码。
https://github.com/jhipster/jhipster-registry/releases

2.2 提交到GitLab

保存到本地Gitlab源码库

2.3 配置文件定制

pom.xml

<dependency>
     <groupId>org.springframework.cloud</groupId>
     <artifactId>spring-cloud-starter-bus-amqp</artifactId>
</dependency>
<dependency>
      <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

application.yml

management:
    security:
        enabled: false
    context-path: /management       # 消息总线的url，这个前缀要加在 /bus/refresh 前面

application-prod.conf

spring:
   rabbitmq:
        host: rmqha_proxy
        port: 56729
        username: guest
        password: guest
        publisher-confirms: true     # 生产者消息确认
        addresses: rmqha_proxy       # 客户端访问server地址, 作为发送者，配置和host一致

2.4 项目构建

在安装了jdk，maven, yarn，nodejs的centos7服务器上执行命令

yarn && yarn install    #前端资源配置生成
mvn -Pprod clean package dockerfile:build   #项目构建并打包成docker镜像，版本号为3.0

2.5 服务启动

docker service create --name base-registry --replicas 1 --network mycloud_base-overlay --constraint node.labels.mycloud.node.type==worker --constraint node.labels.mycloud.node.env==dev --env SPRING_PROFILES_ACTIVE=prod,git --env JHIPSTER_SECURITY_AUTHENTICATION_JWT_SECRET=gdd904a2dffb3eaf28a318b49e0ab986cc51012k --publish 8761:8761 dtr.devops.mycloud.com/common/jhipster-registry:3.0

可通过如下url访问
http://<IP>:8761

3 客户端服务定制

3.1 创建项目

通过jhipster生成一个微服务，名为my-client。

3.2 提交到GitLab

保存到gitLab库git@gitlab.yourcompany.com:root-cloud/mycloud-monitor.git

3.3 配置文件定制

pom.xml

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

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

application-prod.yml

eureka:
    instance:
        prefer-ip-address: true
    client:
        service-url:         # 指向eureka服务器
            defaultZone: http://admin:${jhipster.registry.password}@base-registry:8761/eureka/       

spring: 
   rabbitmq:
        host: rmqha_proxy
        port: 56729
        username: guest
        password: guest
        publisher-confirms: true         # 生产者消息确认
        addresses: rmqha_proxy       # 客户端访问server地址, 作为发送者，配置和host一致

bootstrap-prod.yml

spring:
    cloud:
        config:
            fail-fast: true
            retry:
                initial-interval: 1000
                max-interval: 2000
                max-attempts: 100
            uri: http://admin:${jhipster.registry.password}@base-registry:8761/config       # 指向配置服务器
            # name of the config server\'s property source (file.yml) that we want to use
            name: mq-client
            profile: rd # 注意这里是rd分支，springcloud-config.git上的rd分支
            label: master # toggle to switch to a different version of the configuration as stored in git
jhipster:
    registry:
        password: admin

MyClientApp.java

@(JHipster)RefreshScope     # 加上这个注解 
public class MyClientApp {
    ......
}

3.4 添加测试代码

application-prod.yml

application:
    domain: http://yourcompany.com/2017        # 增加一个配置项

ApplicationProperties

@ConfigurationProperties(prefix = \"application\", ignoreUnknownFields = false)
public class ApplicationProperties {
    private String domain = \"http://default\";
    public String getDomain() {
        return domain;
    }
    public void setDomain(String domain) {
        this.domain = domain;
    }
}

TestResource.java

@RestController
@RequestMapping(\"/management\")
public class TestResource {
private final ApplicationProperties appProperties;

   @GetMapping(\"/mq/property\")
    @Timed
    public ResponseEntity<String> getproperty() {
        return ResponseUtil.wrapOrNotFound(Optional.ofNullable(appProperties.getDomain()));
    }
}
