Google App Engine 上传多模块项目 - 错误配置：验证 XML 错误

Question

我为 Google App Engine 构建了一个在开发服务器中运行良好的 2 模块应用程序。但是当我尝试上传它时，我收到了这个错误：

Bad configuration: XML error validating /Users/mosofsky/Developer/AudienceMarketing/audiencemarketing-ear/target/audiencemarketing-ear-1.0/audiencemarketing-frontend-1.0.war/WEB-INF/appengine-web.xml against /Users/mosofsky/.m2/repository/com/google/appengine/appengine-java-sdk/1.9.15/appengine-java-sdk/appengine-java-sdk-1.9.15/docs/appengine-web.xsd

这是我的两个 appengine-web.xml 文件：

appengine-web.xml 用于受众营销前端

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>audience-marketing</application> 
    <version>${appengine.app.version}</version>
    <module>audiencemarketing-frontend</module>   
    <threadsafe>true</threadsafe>

    <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
    </system-properties>
</appengine-web-app>

受众营销后端的 appengine-web.xml：

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>audience-marketing</application>
    <version>${appengine.app.version}</version>
    <module>audiencemarketing-backend</module>
    <threadsafe>true</threadsafe>

    <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
    </system-properties>

    <instance-class>B8</instance-class>
    <basic-scaling>
        <max-instances>11</max-instances>
    </basic-scaling>

</appengine-web-app>

这是我的 application.xml 文件：

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd" version="5">
  <display-name>appengine-modules-ear</display-name>
  <module>
    <web>
      <web-uri>audiencemarketing-frontend-1.0.war</web-uri>
      <context-root>/audiencemarketing-frontend</context-root>
    </web>
  </module>
  <module>
    <web>
      <web-uri>audiencemarketing-backend-1.0.war</web-uri>
      <context-root>/audiencemarketing-backend</context-root>
    </web>
  </module>
  <library-directory>lib</library-directory>
</application>

我假设通过在 application.xml 文件中首先列出 Audiencemarketing-frontend 它应该被视为默认模块。

我做错了什么？

Answer 1

根据https://cloud.google.com/appengine/docs/java/modules/routing：

默认模块

默认模块是通过显式指定模块名称来定义的 “默认”或不包括模块的名称参数 配置文件。没有指定模块或无效模块的请求是 路由到默认模块。您可以使用管理控制台 适当时为模块指定默认版本。

因此，我想默认的模块不应该有元素。更正是针对

appengine-web.xml 用于受众营销前端

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>audience-marketing</application> 
    <version>${appengine.app.version}</version>
<!--    <module>audiencemarketing-frontend</module>   OFFENDING LINE REMOVED -->
    <threadsafe>true</threadsafe>

    <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
    </system-properties>
</appengine-web-app>

这解决了问题，然后我可以上传并运行我的应用程序。
