struts中文的解决(转)

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 -

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=u5546u54c1u8f66u7c7bu578b
然后在struts-config.xml中设置应用这个资源文件

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

Set Character Encoding
com.huahang.tj.struts.filters.SetCharacterEncodingFilter

encoding
GB2312


ignore
true



Set Character Encoding
action

这里会涉及一个bean,源码如下:
/*

*/
package com.huahang.tj.struts.filters;

import javax.servlet.*;
import java.io.IOException;

/**
*

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:


*

    *
  • encoding - The character encoding to be configured
    * for this request, either conditionally or unconditionally based on
    * the ignore initialization parameter. This parameter
    * is required, so there is no default.

  • *
  • ignore - If set to "true", any character encoding
    * specified by the client is ignored, and the value returned by the
    * selectEncoding() method is set. If set to "false,
    * selectEncoding() is called only if the
    * client has not already specified an encoding. By default, this
    * parameter is set to "true".

  • *

*
*

Although this filter can be used unchanged, it is also easy to
* subclass it and make the selectEncoding() method more
* intelligent about what encoding to choose, based on characteristics of
* the incoming request (such as the values of the Accept-Language
* and User-Agent headers, or a value stashed in the current
* user´s session.

protected String selectEncoding(ServletRequest request) {

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。

我的环境是
windows2000 Professional,tomcat 4.04 , struts1.1b2
