我用JHipster 5.1.0生成了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?

启动用于用户登录的网关后，它无法获取访问令牌并引发错误：

答案 0 :(得分：2)
Feign Client的URI中的主机名不能包含下划线（例如coherence_uaa）。
有一个related JHipster issue，其中_受微服务基本名称的限制，在UAA中也应受限制。 Pull Request fixing that is available here
