Question

我正在尝试按照有关设置Spring MVC的教程来使用Google App Engine。出于这个问题的目的，我正在使用Eclipse，Maven和Ubuntu开发环境。

我能够成功构建我的应用程序，如下面的代码段所示：

但是，当我尝试启动应用程序时，我在控制台中收到以下错误消息：

16-Aug-2010 18:56:30 com.google.apphosting.utils.jetty.JettyLogger info

这怎么可能？从maven构建输出中，它清楚地显示了为构建创建的WEB-INF目录。

以下是目标目录

上的tree输出

我错过了一些完全明显的东西吗？ +代表任何有用的答案！

Answer 1

想出来。

在eclipse中，我需要检查运行配置

在Arguements标签上有一个节目参与部分

它被设置为： --port=8888 /home/james/workspace/springappengine/war

我需要将其更改为以下内容，以便加载展开的war目录： --port=8888 /home/james/workspace/springappengine/target/springappengine

希望这会帮助其他人处于相同的情况，检查运行配置，默认设置对我不起作用！

Maven创建了WEB-INF，但是GAE看不到它
