这是我的web.xml

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.5"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <servlet>
    <servlet-name>Upload</servlet-name>
    <servlet-class>Upload</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>Upload</servlet-name>
    <url-pattern>/upload</url-pattern>
  </servlet-mapping>

    <servlet>
        <servlet-name>SystemServiceServlet</servlet-name>
        <servlet-class>com.google.api.server.spi.SystemServiceServlet</servlet-class>
        <init-param>
            <param-name>services</param-name>
            <param-value>com.company.game.GameApi</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>SystemServiceServlet</servlet-name>
        <url-pattern>/_ah/spi/*</url-pattern>
    </servlet-mapping>

</web-app>

我有一个Google Cloud Endpoint api,GameApi,除了加载花费太长时间的blob之外,它一直运行正常。所以我决定使用Upload servlet on the google website to upload my blobs from user。我基本上将blob文件的xml代码添加到端点api的现有xml代码中,从而生成上面显示的xml。但是从不调用Upload servlet。我在localhost上测试,我可以在_BlobUploadSession_表中看到前端(即android应用程序)已成功将图像发送到具有正确回调URL的blobstore。我知道servlet没有被调用,因为我在入口处有一个println语句。

我是否需要更改web.xml?我是否允许将端点与servlet结合起来,就像我在web.xml中一样?

查看https://cloud.google.com/developers/articles/how-to-build-mobile-app-with-app-engine-backend-tutorial

<servlet>
  <display-name>Remote API Servlet</display-name>
  <servlet-name>RemoteApiServlet</servlet-name>
  <servlet-class>com.google.apphosting.utils.remoteapi.RemoteApiServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
  <servlet-name>RemoteApiServlet</servlet-name>
  <url-pattern>/remote_api</url-pattern>
</servlet-mapping>

虽然我的Android Studio Cloud Endpoints gradle已成功同步,但在上传到GAE时,以下格式(您正在使用)导致错误和上传失败:

<servlet>
    <servlet-name>Upload</servlet-name>
    <servlet-class>Upload</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>Upload</servlet-name>
    <url-pattern>/upload</url-pattern>
  </servlet-mapping>

我需要做的是列出完整的servlet类路径。在你的情况下:

<servlet>
    <servlet-name>Upload</servlet-name>
    <servlet-class>com.company.game.Upload</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>Upload</servlet-name>
    <url-pattern>/upload</url-pattern>
  </servlet-mapping>

希望这有助于某人。
