为什么我的应用程序（struts + spring + jpa）在本地计算机上运行良好，但是GAE给了我500英镑服务器错误＆＃39;当我要求custom-i18n时

============ 

When I try to test i18n, I found app works well in local machine, 
then when I deployed it to GAE, and I got '500 Server Error'.

以下是详细信息：

我发了一封请求：     ENGLISH（http://pang-kimwah.appspot.com/local?lang=en_US&path=http://pang-kimwah.appspot.com/index.jsp）     要么     中文（http://pang-kimwah.appspot.com/local?lang=zh_CN&path=http://pang-kimwah.appspot.com/index.jsp）

我得到了这个：     错误：服务器错误     服务器遇到错误，无法完成您的请求。     请在30秒后再试一次。

最后：     因为struts2-tag＆lt; s：i18n＆gt; GAE不支持/不允许，     所以我新建了一个标签＆lt; my：i18n＆gt;代替＆lt; s：i18n＆gt;通过java.util.Locale.setDefault（语言）。     我认为（不确定）导致异常的键是：java.util.Locale.setDefault（）。     我不知道为什么app在本地机器上运行良好但是GAE？

1 个答案:

答案 0 :(得分：0)

  • 显然，java.util.Locale.setDefault（）是异常的原因。
  • 所以，我删除了语句：'Locale.setDefault（new Locale（lang））;'的 java文件关联i18n-request的动作。
  • 然后i18n无效（总是英语），打开GAE Logs，我发现了 问题的关键：
   Uncaught exception from servlet
    java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle, key welcome

        ......
  • 好吧，我重命名了所有属性（例如shop_en_US.properties）文件 就像这种模式shop_en.properties。
  • 然后，问题解决了。
