Jhipster 控制中心不显示应用程序

Question

我刚刚创建了一个新的 Jhipster 7.0.1 项目，我正在尝试使用 Jhipster 控制中心。

在官方页面，它说：

一旦应用程序在服务器（consul 或 eureka）上注册，它就会 将在列表中可用。

我刚刚启动了我的所有微服务，它们都在 Jhipster 注册表中注册，但它们仍然没有显示在控制中心上。

我是不是忘记做某事了？我没有做任何额外的配置，只是创建项目并启动。

Answer 1

要使用 JHipster 控制中心，您必须编辑

src/main/docker/jhipster-control-center.yml

将其配置为使用您选择的发现服务（在您的情况下是带有 JHipster 注册表的 Eureka）。

说明在

jhipster-control-center.yml

文件注释中，您必须在

jhipster-control-center.yml

中设置2个环境变量，并从

ports

文件中的

jhipster-registry.yml

中删除“127.0.0.1：”前缀。

Answer 2

此处不列出实例信息。我有 jhipster-registry 和 jhipster-control-center 通过 Docker 运行，我的测试服务通过 IntelliJ 运行。我以这种方式配置我的文件，基本上我更改了 EUREKA_CLIENT_SERVICE_URL_DEFAULTZONE 变量以使用容器服务名称，因为它们都位于同一网络上。 jhipster-control-center 没有作为注册实例出现在 eureka 中。

## How to use JHCC docker compose
# To allow JHCC to reach JHipster application from a docker container note that we set the host as host.docker.internal
# To reach the application from a browser, you need to add '127.0.0.1 host.docker.internal' to your hosts file.
### Discovery mode
# JHCC support 3 kinds of discovery mode: Consul, Eureka and static
# In order to use one, please set SPRING_PROFILES_ACTIVE to one (and only one) of this values: consul,eureka,static
### Discovery properties
# According to the discovery mode choose as Spring profile, you have to set the right properties
# please note that current properties are set to run JHCC with default values, personalize them if needed
# and remove those from other modes. You can only have one mode active.
#### Eureka
#       - EUREKA_CLIENT_SERVICE_URL_DEFAULTZONE=http://admin:[email protected]:8761/eureka/
#### Consul
#       - SPRING_CLOUD_CONSUL_HOST=host.docker.internal
#       - SPRING_CLOUD_CONSUL_PORT=8500
#### Static
# Add instances to "MyApp"
#       - SPRING_CLOUD_DISCOVERY_CLIENT_SIMPLE_INSTANCES_MYAPP_0_URI=http://host.docker.internal:8081
#       - SPRING_CLOUD_DISCOVERY_CLIENT_SIMPLE_INSTANCES_MYAPP_1_URI=http://host.docker.internal:8082
# Or add a new application named MyNewApp
#       - SPRING_CLOUD_DISCOVERY_CLIENT_SIMPLE_INSTANCES_MYNEWAPP_0_URI=http://host.docker.internal:8080
# This configuration is intended for development purpose, it's **your** responsibility to harden it for production

#### IMPORTANT
# If you choose Consul or Eureka mode:
# Do not forget to remove the prefix "127.0.0.1" in front of their port in order to expose them.
# This is required because JHCC need to communicate with Consul or Eureka.
# - In Consul mode, the ports are in the consul.yml file.
# - In Eureka mode, the ports are in the jhipster-registry.yml file.
