【问题描述】：

我正在尝试遵循有关设置 Spring MVC 以在 Google App Engine 上工作的教程。出于这个问题的目的，我使用的是 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 sn-p 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，它清楚地显示了正在为构建创建的 WEB-INF 目录。

以下是我的目标目录上的tree 输出

james@nevada:~/workspace/springappengine/target$ pwd
/home/james/workspace/springappengine/target

15 directories, 17 files

我是否遗漏了一些非常明显的东西？ +代表任何有用的答案！

谢谢

【问题讨论】：

您是否检查了springappengine.war 文件的内容以确保它与目标目录中的输出匹配？

标签： google-app-engine maven-2 spring-mvc

【解决方案1】：

想通了。

在eclipse中，我需要检查运行配置

在Arguements 选项卡上有一个程序争论部分

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

我需要将其更改为以下内容，以便加载爆炸的战争目录： --port=8888 /home/james/workspace/springappengine/target/springappengine

希望这对处于相同情况的其他人有所帮助，检查运行配置，默认设置对我不起作用！
