我正在尝试将 JHipster 用于使用微服务的项目，但最新的 JHipster Registry 不会让我的网关或微服务访问配置服务器并拒绝它们。

我安装了 JHipster Vagrant DevBox，然后用来docker run -p 8761:8761 jhipster/jhipster-registry运行 JHipster 注册表。然后，我在此之后生成了一个网关和 2 个微服务，并且它起作用了。

但是后来我想使用来自 GitHub 的 JHipster Registry，所以我克隆了它并运行了它（显然它同时已更新到 2.0.0）。遗憾的是，网关和微服务无法访问此注册表。不过，他们仍然能够访问 Docker 镜像注册表（我想 Docker 没有更新它）。但由于它更漂亮，而且可能更新，我想使用最新版本的注册表，与 GitHub 上的相同。所以我尝试用docker pull. 现在它不适用于任何一个注册表——Docker 镜像或 GitHub 克隆。

当注册表正在运行并且我运行网关或微服务时，我得到了 6 倍：

2016-05-10 15:39:07.511 DEBUG 20706 --- [           main] s.n.www.protocol.http.HttpURLConnection  : sun.net.www.MessageHeader@86ba8f5 pairs: {GET /config/gateway/dev/master HTTP/1.1: null}{Accept: application/json, application/*+json}{User-Agent: Java/1.8.0_91}{Host: localhost:8761}{Connection: keep-alive}

然后我得到一个错误：

2016-05-10 15:39:13.781 ERROR 20706 --- [           main] o.s.boot.SpringApplication               : Application startup failed

然后我得到Java异常：

最后是BUILD FAILURE一个 Maven 错误：

在注册表的外壳中，我也得到了这条线 6 次：

2016-05-10 15:39:07.519 DEBUG 17958 --- [io-8761-exec-10] i.g.j.r.s.Http401UnauthorizedEntryPoint  : Pre-authenticated entry point called. Rejecting access

我尝试更新所有内容，并且目前正在尝试降级（因为文档说“我们建议您使用与用于 JHipster 生成器的版本相同的版本标签”，但我认为它不会在 JHipster 之后工作Registry 的最新版本是 2.0.0，JHipster 生成器在 3.0 版本中引入了微服务），我也尝试直接从 central-server-config 复制秘密到应用程序的配置，但显然无济于事。

你能帮我解决这个问题吗？

非常感谢您提前。

编辑：

我尝试使用 将 JHipster 更新到 3.2.1 npm install -g generator-jhipster，这显然有效，但是当我运行时yo jhipster，Yeoman 仍然使用 JHipster 3.1.0。实际上，即使我用 卸载 JHipster npm uninstall -g generator-jhipster，Yeoman 仍然可以使用 JHipster 3.1.0...

编辑：

如果我在本地重新安装所有东西（在我使用的目录中yo jhipster），它工作正常。但是，我仍然无法在 Yeoman 中全局更新 JHipster。当我尝试使用npm install -g generator-jhipster时，它会将 JHipster 全局更新为 3.2.1，但 Yeoman 仍然使用 3.1.0。如果我尝试使用yo/"Update your generators"/generator-jhipster 更新 JHipster，我会收到错误消息：

I've just updated your generators. Remember, you can update
a specific generator with npm by running:

    npm install -g generator-_______

当我尝试运行时，使用sudo会做同样的事情并给我这个：sudo suyo

编辑：

好的，即使使用本地安装它也不起作用...网关确实可以访问注册表，但是当我尝试访问 localhost:8080 时它会显示一个调试页面。实际上，在生成过程中，我permission denied又得到了一个，并且缺少依赖项（gulp-rev）。

我刚刚看到这个：“使用标签拥有稳定版本是明智的：JHipster DevBox标签与JHipster Generator标签相同，因此使用DevBox v3.2.0也意味着使用生成器v3.2.0”上DevBox GitHub页面，所以也许我会删除并再次下载DevBox......

这是因为您将 JHipster Registry 升级到了 2.0.0 版本。这个新版本是安全的，这就是为什么您有 401“未经身份验证”错误，因为您没有提供任何登录名/密码来连接。

3个解决方案：

  • 继续使用与您的 JHipster 版本匹配的旧 JHipster Registry 版本。
  • 将登录名/密码（默认为 admin/admin）添加到您的 Eureka 和 Spring Cloud Config URL。有关保护 JHipster Registry 的详细文档在这里- 在撰写本文时它不完整，但我会尽快更新它
  • 更新到 JHipster v3.2.1，这意味着与 JHipster Registry v2.0.0 一起使用，并且所有内容都将自动配置。

当使用从 github 中提取的最新 JHipster Registry 并在 IntelliJ IDEA 本地运行时，我发现了相同的行为——服务器将启动，但前端无法提供服务。

结果是运行/调试配置中的空白工作目录存在问题。一旦填充完毕，就可以从 IDE 中找到工作了。
