在微服务中使用jhipster应用程序

Question

首先，我是Jhipster的新手。我已经创建了jhipster网关(前端)与angular无应用程序(后端)。

我希望这将不会工作，因为后端不存在/工作，所有的服务调用都将通过后端访问数据库。

当我尝试使用http://localhost:8080访问前端时，我可以看到一切都在工作。我不确定是怎么做到的。有人能解释一下吗？

JHipster v6.10.5用于此目的。

谢谢Shirish

/**
 * The Employee entity.
 * @author Shirish Bathe
 */
entity Employee {
    name String required unique
    dept String
}

现在我有了使用http://localhost:8080的访问网关，并尝试访问employee实体。我可以在表格中看到(假的)数据。

因此，即使后端应用程序不存在，应用程序也可以正常工作。多么?我错过了什么吗？

网关包含整个UI。微服务在您定义实体时开始发挥作用。这些不是由网关管理的(但UI是)。这张概览图很好地描述了架构：
