说假话,你们的方法都做的复杂了,Java本身就支持多国言语编码,不需要写任何顺序,可以很简单的完成。秘诀就是两点:
1、所有HTML/JSP页面全部采用UTF-8编码
2、客户端浏览器完全支持UTF-8编码
步骤:1、首先把所有的HTML/JSP的ContentType都设为UTF-8
2、然后对于JSP顺序中的非ASCII码提示信息都不应该写在顺序外面,都应该放在application.properties外面一致管理。
3、对HTML用native2ascii工具一致做一次处置,把HTML中的非ASCII码都转换为Unicode编码。
4、针对不同的言语,写不同的application.properties,比如说简体中文是application_zh_CN.properties,繁体中文是application_zh_TW.properties这样,然后对这些配置信息文件同样用native2ascii工具处置一次,把非ASCII码统统转为Unicode编码。
5、在Servlet的request.getCharacterEncoding()获得客户端的操作系统默认编码,然后set到Struts的HTTPSession的Locale中。
OK!现在不同的客户拜访,就会显示不同的言语版本了。你可以看看此时你的浏览器的字符集,就是UTF-8。现在你的网站和Google一样了,嘿嘿,其实你有心的话,看看你的浏览器拜访Google的时分是什么字符集吧
切记:所有的HTML/JSP都要设为UTF-8编码,所有的文件中的非ASCII码字符都要用native2ascii工具转为用ASCII表示的Unicode编码。--------------------------------------------------------------------------------原创----------------------------------------上面所述是我从网上下的一篇于中文问题的处置方案,确切的说应该是关于Struts的国际化问题,下面我结合我的实践谈谈详细如何完成Struts的国际化问题,我对实际不是十分精通,我只能完全凭自己的了解和实践来讲述,所以下面讲的内容可能不是十分正确,还请大家原谅。但有一点可以肯定,我通过自己的努力处置了Struts的中文问题,并完成Struts的国际化,其实一切并不复杂,下面是详细步骤:
0.遇到的问题(这些问题也许不会同时出现)a.中文数据从数据库中到jsp中后就变成了"????"b.做好的中文properties文件,其中的中文value在页面显示乱码c.jsp文件中的中文到浏览器后显示时也是乱码(建议不要在jsp文件中输出中文,尽量放在properties文件中)d.由jsp传给bean的中文值,再由bean传回页面又是乱码e.当改换本地浏览器的言语选项时,Web应用顺序不能自动根据你的locale选择适宜的*.properties文件。招致Web应用顺序不能国际化。1.环境:Web服务器: Tomcat 5.0.19操作系统: Win2000 ServerJVM : jdk 1.4数 据 库: Oracle 8.1.7开发工具: struts studio 5.2 pro for eclipse2.先将所有*.jsp 网页中扫尾处参与
%@ page language="java" contentType="text/html; charset=utf-8" %再设置html:html locale = "true"
3.然后编辑好两个*.properties文件,放在classes文件夹下你指定的中央,这里是放在/web-inf/classes/com/wiley 下,它们分别是:
ApplicationResources.properties (英文资源文件)ApplicationResources_zh.properties (中文资源文件)随便用什么工具编写都行啊!4.将ApplicationResources_zh.properties转码成gb2312。上面引文说要转成UTF-8,结果我试了,不行。转成gb2312就行了,操作是。将ApplicationResources_zh.properties更名为ApplicationResources_xx.properties在DOS命令行进入ApplicationResources_xx.properties所在的文件夹运用命令:native2ascii -encoding gb2312 ApplicationResources_xx.properties ApplicationResources_zh.properties(至于你为什么会出现“native2ascii不是内部命令”,,请查其它资料,可能你要设置环境变量,由于他是jdk的文件夹bin下的一个应用顺序)5.腰带接上去配置struts-config.xml,很简单,我们参与:
message-resources parameter="com.wiley.ApplicationResources"/ 就行了;
到此已能处置大少数中文问题。如上面所说的a,b,e 现在打开浏览器,选择菜单:工具》internet选项》言语,将“中文-中国[zh-cn]”删掉,添加一个“英语-英国[zh-gb]”确定后,重启 Tomcat,输出网址你就会发现,你的页面的文本信息就会用的是ApplicationResources.properties (英文资源文件)中的内容。假如换回“中文-中国[zh-cn]”,它就会显示ApplicationResources_zh.properties (中文资源文件)中的中文内容。
至于问题“c.jsp文件中的中文到浏览器后显示时也是乱码” 你就要用与第4步相似的方法来重新对*.jsp 文件编码,这时-encoding的参数就要用UTF-8了,假如你用的也是struts studio 5.2 pro for eclipse工具,这一步就免了。它会自动用UTF-8的格式存储。至于问题“d.由jsp传给bean的中文值,再由bean传回页面又是乱码”的处置,我只是加了个过滤器。你可以现在web.xml中参与:filterfilter-nameSet Character Encoding/filter-namefilter-classcom.wiley.SetCharacterEncodingFilter/filter-classinit-paramparam-nameencoding/param-nameparam-valueutf-8/param-value/init-paraminit-paramparam-nameignore/param-nameparam-valuetrue/param-value/init-param/filterfilter-mappingfilter-nameSet Character Encoding/filter-nameservlet-nameaction/servlet-name/filter-mapping
然后在你指定的包内加个java文件 我放在了/web-inf/classes/com/wiley 里,下面是源代码:/** XP Forum** Copyright (c) 2002-2003 RedSoft Group. All rights reserved.**/package com.huahang.tj.struts.filters;
import javax.servlet.*;import java.io.IOException;
/*** pFilter that sets the character encoding to be used in parsing the* incoming request, either unconditionally or only if the client did not* specify a character encoding.

}
/*** Place this filter into service.** @param filterConfig The filter configuration object*/public void init(FilterConfig filterConfig) throws ServletException {
this.filterConfig = filterConfig;this.encoding = filterConfig.getInitParameter("encoding");String value = filterConfig.getInitParameter("ignore");if (value == null)this.ignore = true;else if (value.equalsIgnoreCase("true"))this.ignore = true;else if (value.equalsIgnoreCase("yes"))this.ignore = true;elsethis.ignore = false;

return (this.encoding);
}
}//EOC到此我遇到的中文问题已全部失掉处置,并从中了解到struts的国际化的深刻含义。我团体觉得struts作为一个功能弱小的应用框架,应该早就思索到它的国际化问题,并在实际应用中不会很复杂,只需我们遵照一些规则,就可以尽情享用struts给我们带来的无穷乐趣。希望以上所述对大家有所协助。
