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：

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
* users session.</p>

protected string selectencoding(servletrequest request) {

}
}//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。
