Question

为什么Yeoman Jhipster generator会为JHipster UAA生成JHipster Registry服务注册代码，即使我们指定在JHipster Registry应用生成期间我们不会使用Microservice

以下是我在Micorservice应用程序生成期间选择的选项

? (1/16) Which *type* of application would you like to create? Microservice application
? (2/16) What is the base name of your application? service
? (3/16) As you are running in a microservice architecture, on which port would like your server to run? It should be unique to avoid port conflicts. 8081
? (4/16) What is your default Java package name? com.test

################ Jhipster registry not to be used ##########################
? (5/16) Do you want to use the JHipster Registry to configure, monitor and scale your microservices and gateways? No

################ Use Jhipster UAA #######################################
? (6/16) Which *type* of authentication would you like to use? [BETA] Authentication with JHipster UAA server (the server must be generated separately)
? (7/16) What is the folder path of your UAA application? ../uaa

? (8/16) Which *type* of database would you like to use? SQL (H2, MySQL, MariaDB, PostgreSQL, Oracle)
? (9/16) Which *production* database would you like to use? PostgreSQL
? (10/16) Which *development* database would you like to use? H2 with in-memory persistence
? (11/16) Do you want to use Hibernate 2nd level cache? No
? (12/16) Would you like to use Maven or Gradle for building the backend? Maven
? (13/16) Which other technologies would you like to use?
? (14/16) Would you like to enable internationalization support? No
? (15/16) Besides JUnit and Karma, which testing frameworks would you like to use?
? (16/16) Would you like to install other generators from the JHipster Marketplace? No

在生成应用程序后选择这些选项后，UAA内的application-dev.yml具有以下配置

jhipster:
    http:
        version: V_1_1 # To use HTTP/2 you will need SSL support (see above the "server.ssl" configuration)
    # CORS is only enabled by default with the "dev" profile, so BrowserSync can access the API
    cors:
        allowed-origins: "*"
        allowed-methods: GET, PUT, POST, DELETE, OPTIONS
        allowed-headers: "*"
        exposed-headers:
        allow-credentials: true
        max-age: 1800
    security:
        client-authorization:
            access-token-uri: http://uaa/oauth/token
            token-service-id: uaa ############ Why does it need service ID if it's not dependenty on Jhipster Registry
            client-id: internal
            client-secret: internal

以下是UAA

的两行

access-token-uri: http://uaa/oauth/token
token-service-id: uaa

可以看出，微服务配置是为了寻找名为uaa的服务而创建的。如果此应用程序不依赖于Jhipster Registry或任何其他注册表，为什么此配置正在寻找已注册的服务名称？

我希望我只需要指定UAA URL和凭据，这应该是没有注册表的。

感谢任何帮助。

很抱歉，您的回答很晚。生成的代码中唯一真正不必要的部分是“ token-service-id”，因为它专门用于在应用程序堆栈内部（例如Netflix Eureka，Consul等）进行服务发现。

如果没有服务发现，则仍然需要您的应用程序才能访问UAA。因此，仅保留access-token-uri就足够了，而无需填充token-service-id标志。

如果您的应用程序能够解析提供的URI，则基本上可以正常工作。但是，如果没有，请随时在GitHub上发布问题。

没有注册表的JHIpster微服务应用程序为UAA注册表生成配置
