在GAE中将多种服务打包到Java 8的war文件中 [英] Packaging multiple services into a war file for Java 8 in GAE

问题描述

在Google App Engine(GAE)中，您可以将多个服务打包到一个分解的WAR文件(也称为EAR文件)中，但前提是您的应用程序在Java 7下运行.这不适用于Java 8:

In Google App Engine (GAE), you can package multiple services into a single exploded WAR file (a.k.a EAR file) but only if your app is running under Java 7. This does not work for Java 8:

使用服务的App Engine应用程序被组织为 解压缩的Java Enterprise Archive(EAR)目录结构.这 顶级EAR目录包含一个META-INF子目录，以及一个 应用中每个服务的单独目录.请注意，EAR是 仅支持Java 7运行时，不支持Java 8运行时.

An App Engine application that uses services is organized as an unpacked Java Enterprise Archive (EAR) directory structure. The top-level EAR directory contains a single META-INF subdirectory, and a separate directory for each service in the app. Note that EAR is supported for the Java 7 runtime only, not for the Java 8 runtime.

我在GAE文档中找不到任何指示如何将多个服务打包到单个WAR文件中的东西.

I couldn't find anything in the GAE docs that indicates how you package multiple services into a single WAR file.

我意识到我可以为每种服务创建一个单独的WAR文件，但是Google提供的用于测试您的应用的本地开发服务器仅接受一个WAR文件.我可以使用不同的端口运行开发服务器的多个实例，但这似乎有些混乱.

I realize that I can create a separate WAR file for each service but the local dev server supplied by Google for testing your app only accepts a single WAR file. I could run multiple instances of the dev server using different ports but that seems kind of messy.

推荐答案

Google确实提供了解决方案，但文档记录在最晦涩的位置:

Google does have a solution but they documented in the most obscure location:

https://cloud.google.com/appengine /docs/standard/java/tools/migrate-gradle

很容易忽略这一点，因为文档的标题是:

It was easy to overlook this because the title of the document is:

迁移到基于Cloud SDK的Gradle插件

Migrating to the Cloud SDK-based Gradle plugin

如果您是从头开始构建应用程序，则不会迁移任何内容，因此可以轻松跳过此文档.确实应该在以下位置对此文件进行记录:

If you are building an app from scratch, you are not migrating anything and would easily skip this documentation. It should really have been documented at:

https://cloud.google.com/appengine/docs /standard/java/tools/gradle

可以在以下位置找到一些其他说明:
