#google-apis-explorer 中的 Umbrella 异常

Question

在将 Google Cloud Endpoints Java 框架升级到 v2，以及使用 Google API Explorer #google-apis-explorer 从 Java 7 升级到 Java 8 后，资源管理器会打开 API 列表，但当打开 API 方法执行调用时，没有任何返回，似乎找不到 API 方法 并抛出这个 Umbrella 异常，即使调用 API 工作正常。

您如何注释您的 API？迁移后我遇到了同样的问题，问题是小写的httpMethod，在迁移之前我的API看起来像这样：

@ApiMethod(name = "getSomething", httpMethod = "get")

但迁移后你必须使用大写的httpMethods：

@ApiMethod(name = "getSomething", httpMethod = "GET")

或

@ApiMethod(name = "getSomething", httpMethod = HttpMethod.GET)
