在gwt.xml中设置语言环境不起作用 [英] Setting locales in gwt.xml do not work

问题描述

 < module rename-to =UIGenerator> 
<继承了name =com.google.gwt.http.HTTP/> 
<继承了name =com.google.gwt.xml.XML/> 
<继承了name =com.google.gwt.i18n.I18N/> 
< inherits name =com.google.gwt.i18n.CldrLocales/> 
< set-configuration-property name =locale.useragentvalue =Y/> 
< extend-property name =localevalues =de/> 
< extend-property name =localevalues =fr/> 
< set-property name =localevalue =de，fr/> 
< set-property-fallback name =localevalue =de/> 
< entry-pointclass =mypackage.UIGeneratorEntryPoint/> 
< / module> 
  

但是每当我尝试使用语言环境时，它都会返回默认的英语。

  LocaleInfo.getAvailableLocaleNames（）;此返回数组的字符串只有一个值 - 默认
  

如果我设置了它，其他！

预先感谢您！

解决方案

运行应用程序，因为你的gwt.xml无效。

  [致命错误]：13：53：元素类型set-configuration-属性必须后跟任一属性规范，>或/>。 
  

在 value 之前放置一个空格，如下所示：

 < set-configuration-property name =locale.useragentvalue =Y/> 
  

我在同一个上下文中发布了一个答案。

请查看如何将语言环境设置为GWT DateBox

In my module xml file I have this:

 <module rename-to="UIGenerator">
 <inherits name="com.google.gwt.http.HTTP" />
 <inherits name="com.google.gwt.xml.XML" />
 <inherits name="com.google.gwt.i18n.I18N" />
 <inherits name="com.google.gwt.i18n.CldrLocales" />
 <set-configuration-property name="locale.useragent"value="Y" />
 <extend-property name="locale" values="de" />
 <extend-property name="locale" values="fr" />
 <set-property name="locale" value="de, fr" />
 <set-property-fallback name="locale" value="de" />
 <entry-pointclass="mypackage.UIGeneratorEntryPoint" />
 </module>

But every time when I try to use locales it returns me default one which is English.

   LocaleInfo.getAvailableLocaleNames(); this return Array of String with only one value   - default 

IF I set It works but only for German without others!

Thank you in advance!

解决方案

I got an error while running application because of invalid your gwt.xml.

[Fatal Error] :13:53: Element type "set-configuration-property" must be followed by either attribute specifications, ">" or "/>".

put a space before value as shown below:

<set-configuration-property name="locale.useragent" value="Y" /> 

I have posted a answer in the same context.

Please have a look at How do I set locale to GWT DateBox

Complete Code:

Note: just change com.gwt.test.client.GWTTestProject it with you actual Entry Point clas in your gwt.xml file.
