1.使ApplicationResources.properties支持中文建立一个ApplicationResources_ISO.properties文件,把应用程序用的message都写进去,然后在dos下执行这个命令,native2ascii -encoding gb2312 ApplicationResources_ISO.properties ApplicationResources.properties这样就会将ISO编码的ApplicationResources转换成GB2312编码的格式了,同时保存到ApplicationResources.properties.native2ascii这个工具是jdk自带的一个东东,所以如果path都设定正确就可以直接运行了,你可以在$java_home$/bin下找到他。转换后的中文类似于这个样子iso 格式下 :tj.type=商品车类型gb2312格式下 :tj.type=/u5546/u54c1/u8f66/u7c7b/u578b然后在struts-config.xml中设置应用这个资源文件 <message-resources parameter="com.huahang.tj.ApplicationResources" key="org.apache.struts.action.MESSAGE" />开发jsp时在jsp的开头写上<%@ page contentType="text/html; charset=gb2312" %>,将字符集设置成gb2312就可以了。2.使数据库操作支持中文。数据库操作支持中文一直让我比较头痛,但是感谢善解人衣向我推荐了www.chinaxp.org,这个网站是用struts框架开发的,而且开放源码,下载了源码后发现它的中文处理得很好,阅读部分源码,没有发现什么特殊的字符集转换,很纳闷,偶然看到楼上网友留言知道原来servlet可以统一设置字符转换。chinaxp.org就是这么做的。在web.xml中加上 <filter> <filter-name>Set Character Encoding</filter-name> <filter-class>com.huahang.tj.struts.filters.SetCharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>GB2312</param-value> </init-param> <init-param> <param-name>ignore</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>Set Character Encoding</filter-name> <servlet-name>action</servlet-name> </filter-mapping>这里会涉及一个bean,源码如下:/* * XP Forum * * Copyright (c) 2002-2003 RedSoft Group.
