无法从JHipster UAA获取OAUTH2令牌

我用JHipster 5.1.0生成了一个UAA服务器。我选择PostgreSQL作为数据库类型

它连接到我的jhipster注册表，然后我生成了一个微服务和一个网关，如下所示：

$ mkdir coherence-uaa && cd coherence-uaa
$ yo jhipster
? Which *type* of application would you like to create? Microservice UAA service
? 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. 9999
? What is your default Java package name? de.stytex.foobar
? Which *type* of database would you like to use? SQL (H2, MySQL, PostgreSQL, Oracle)
? Which *production* database would you like to use? PostgreSQL
? Which *development* database would you like to use? H2 with disk-based persistence
? Do you want to use Hibernate 2nd level cache? Hazelcast
? Do you want to use a search engine in your application? No
? Would you like to use Maven or Gradle for building the backend? Maven
? Would you like to enable internationalization support? Yes
? Please choose the native language of the application? English
? Please choose additional languages to install
? Which testing frameworks would you like to use?
[...]
$ ./mvnw

$ mkdir coherence-gateway && cd coherence-gateway
$ yo jhipster
? Which *type* of application would you like to create? Microservice gateway
? What is the base name of your application? gateway
? 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. 8080
? What is your default Java package name? de.stytex.foobar
? Which service discovery server do you want to use? JHipster Registry (uses Eureka, provides Spring Cloud Config support and monitoring dashboards)
? Which *type* of authentication would you like to use? Authentication with JHipster UAA server (the server must be generated separately)
? What is the folder path of your UAA application? ../coherence-uaa
? Which *type* of database would you like to use? SQL (H2, MySQL, PostgreSQL, Oracle)
? Which *production* database would you like to use? PostgreSQL
? Which *development* database would you like to use? H2 with disk-based persistence
? Do you want to use Hibernate 2nd level cache? Hazelcast
? Do you want to use a search engine in your application? No
? Do you want to use clustered HTTP sessions? No
? Do you want to use WebSockets? No
? Would you like to use Maven or Gradle for building the backend? Gradle
? Would you like to use the LibSass stylesheet preprocessor for your CSS? No
? Would you like to enable internationalization support? Yes
? Please choose the native language of the application? English

启动用户登录网关后，无法获取访问令牌并引发错误：

coherence\u ua

）

有一个例子是，

\uu

受到微服务基本名称的限制，在UAAs中也应该受到限制

我重新创建了名为“UAA”的UAA服务器，然后问题就解决了。在生成的网关中，名称“UAA”似乎是硬编码的。我仅使用名称“UAA”重新创建了UAA服务器，然后问题就解决了。似乎名称“UAA”是在生成的网关中硬编码的。
