AppEngine下的RPC序列化策略文件
GWT / AppEngine RPC 接口正在困扰着我！我收到如下错误：
INFO：javax.servlet.ServletContext log：UserService：ERROR：未找到序列化策略文件“/55585D0849A4549E3FCE91B33725B02F.gwt.rpc”；您是否忘记将其包含在此部署中？
每次我启动 Devserver 时。我已在 appengine-web.xml 中正确设置了 public-root（除了 .gwt.rpc 之外，应用程序的其余部分均正常运行） > 文件）。
<static-files>
<include path="**" />
<include path="**.nocache.*" expiration="0s" />
<include path="**.rpc" expiration="0s" />
<include path="**.cache.*" expiration="365d" />
</static-files>
<resource-files>
<include path="**.gwt.rpc" />
</resource-files>
我做错了什么？请帮忙！
The GWT / AppEngine RPC interface is eating at me! I get errors such as this:
INFO: javax.servlet.ServletContext log: UserService: ERROR: The serialization policy file '/55585D0849A4549E3FCE91B33725B02F.gwt.rpc' was not found; did you forget to include it in this deployment?
every time I start the Devserver. I have correctly set the public-root in appengine-web.xml (the rest of the application is served OK except for the .gwt.rpc files).
<static-files>
<include path="**" />
<include path="**.nocache.*" expiration="0s" />
<include path="**.rpc" expiration="0s" />
<include path="**.cache.*" expiration="365d" />
</static-files>
<resource-files>
<include path="**.gwt.rpc" />
</resource-files>
What am I doing wrong? Help please!

经过一番实验后，我得出以下结论：
.rpc文件包含在 appengine 部署（appengine-web.xml文件）中，并注意缓存问题！ （例如序列化策略的更改）appengine-web.xml中使用public-root标记：删除welcome 文件（例如索引.html) 位于war目录的/中，并对 GWT 进行适当的更改以查找其文件更新 servlet
url-pattern标签指向 GWT 生成的目录内war目录对于关联的 servlet对于
tasks（即web hooks），不要更改因此，唯一需要了解 GWT 生成文件夹的地方位于
web.xml中。当然，GWT项目的welcome-file也必须进行改编。希望这对某人有帮助
After some experimenting, here is what I came up with:
.rpcfiles included in the appengine deployment (appengine-web.xmlfile) and beware of caching issues! (e.g. changes in serialization policy)public-roottag inappengine-web.xml: drop thewelcome file(e.g. index.html) in/of thewardirectory and make the appropriate change for GWT to find its filesUpdate the servlets
url-patterntags to point inside GWT generated directory inside thewardirectoryFor servlets associated with
tasks(i.e.web hooks), do not change theurl-patternHence, the only place that requires some knowledge of the GWT generated folder resides in
web.xml. Of course, thewelcome-fileof the GWT project must also be adapted.Hope this helps somebody
我在部署的 GAE 服务器上遇到了同样的问题，直到我为资源文件部分添加了 rpc include 后，错误才消失。这就是我最终得到的结果：
I had the same problem on the deployed GAE server and it wasn't until I added the rpc include for the resource-files section that the error went away. Here's what I ended up with:
