转载 struts中文的解决 发表时间: 2002-9-13 上午9:10 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. All rights reserved. * */ package com.huahang.tj.struts.filters;
import javax.servlet.*; import java.io.IOException;
/** * <p>Filter 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. Configuration of this filter is based on * the following initialization parameters:</p> * <ul> * <li><strong>encoding</strong> - The character encoding to be configured * for this request, either conditionally or unconditionally based on * the <code>ignore</code> initialization parameter. This parameter * is required, so there is no default.</li> * <li><strong>ignore</strong> - If set to "true", any character encoding * specified by the client is ignored, and the value returned by the * <code>selectEncoding()</code> method is set. If set to "false, * <code>selectEncoding()</code> is called <strong>only</strong> if the * client has not already specified an encoding. By default, this * parameter is set to "true".</li> * </ul> * * <p>Although this filter can be used unchanged, it is also easy to * subclass it and make the <code>selectEncoding()</code> method more * intelligent about what encoding to choose, based on characteristics of * the incoming request (such as the values of the <code>Accept-Language</code> * and <code>User-Agent</code> headers, or a value stashed in the current * user's session.</p> * * @author <a href="mailto:[email protected]">John Wong</a> * * @version $Id: SetCharacterEncodingFilter.java,v 1.1 2002/04/10 13:59:27 johnwong Exp $ */ public class SetCharacterEncodingFilter implements Filter {
// ----------------------------------------------------- Instance Variables

}

// Conditionally select and set the character encoding to be used if (ignore || (request.getCharacterEncoding() == null)) { String encoding = selectEncoding(request); if (encoding != null) request.setCharacterEncoding(encoding); }
// Pass control on to the next filter chain.doFilter(request, response);
}
/** * 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; else this.ignore = false;
}
// ------------------------------------------------------ Protected Methods

return (this.encoding);
}
}//EOC 加上这个后,在action中就可以直接从form中接收gb2312编码的数据了,返回时自然也是gb2312了。 但是这个好像需要servlet 2.2以上的容器
综合上面的方法,我解决了struts中的中文问题,现在还没发现新的问题。
