java - Google App Engine 上传多模块项目 - 配置错误 : XML error validating

Question

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

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:

用于受众营销前端的 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-frontend</module>   
    <threadsafe>true</threadsafe>

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

用于受众营销后端的 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 :

Default module

The default module is defined by explicitly giving a module the name "default," or by not including the name parameter in the module's config file. Requests that specify no module or an invalid module are routed to the default module. You can use the Admin Console to designate a default version for a module, when appropriate.

因此我想默认的模块不应该有元素。更正是针对

用于受众营销前端的 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-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，然后我就可以上传并运行我的应用了。
