Google Cloud Endpoints - 无法加载服务

Question

一些非常奇怪的事情刚刚开始发生。 我们在 Google Cloud Endpoints 上的 API 无法启动。 在尝试部署到新的测试环境后就发生了这种情况。 现在我们也无法部署到旧的测试环境。

我们一如既往地部署 API：

gcloud endpoints services deploy openapi.json

请注意，我们在 openapi 中将“host”更改为新的测试 URL。

openapi.json

{
    "swagger": "2.0",
        "info": {
        "version": "1.2.0",
        "title": "Our App API"
    },
    "host": "test2-ourappapi.appspot.com",
    "basePath": "/_ah/api",
    "schemes": [
        "https"
    ],
    "consumes": [
        "application/json"
    ],
    "produces": [
        "application/json"
    ],
    "paths": {
       ...
    }
}

现在部署到 GAE 后，这会出现在日志中。

研究后，似乎一种解决方法是注释掉 web.xml 中的行（见下文）。

我可以确认这有效。 但是，文档表明删除这些行会绕过 GCE 对端点的管理。

发生什么事了？

请注意，我已更新到最新的 Google Cloud SDK。 设置项目后，我还运行了“gcloud auth application-default login”。

Answer 1

我想我发现了问题。 这是在 POM 中。

<dependency>
    <groupId>com.google.endpoints</groupId>
    <artifactId>endpoints-management-control-appengine-all</artifactId>
    <version>1.0.14</version>
</dependency>

当版本更改为1.0.15时似乎可以工作。 我还不太相信它。 所以，我还得再用一段时间。
