在网上收集了一些关于Struts中文显示的资料,你试一下。对你的问题,完全可参考。
我在新的(2003.8.6)JSPStudio中加入了中文处理的代码,人兴趣可到ftp://210.36.70.51下载。一、
我在网上下载了一个 struts 结构的源程序,数据库是 MySQL,数据库里的字段只能输入一个汉字,超过的不显示。而且不能进行中文操作,页面显示乱码,我猜可能是建立连接时需要进行字符集的转换,这是一个外国人写的程序,我没找到到数据库连接的语句,不知如何是好,如果您肯帮助我,麻烦您把邮箱留一下,我 classes 发到您的邮箱里,请您帮我看一下应该怎样改?我万分感谢!加一个转换中文的:
package com.aurel.track.user;
public class ToChinese { /**
* 处理中文
* @param ss 待处理的字符串
* @return 处理之后的字符串
*/
public String toChinese(String ss) {
//处理中文问题
if (ss != null) {
try {
String temp_p = ss;
byte[] temp_t = temp_p.getBytes("ISO8859-1");
ss = new String(temp_t);
}
catch (Exception e) {
System.err.println("toChinese exception:" + e.getMessage());
System.err.println("The String is:" + ss);
}
}
return ss;
}
}
在得到参数的时候,比如RegistrationForm
在RegistrationForm方法里面加上ToChinese mychinese = new ToChinese();,就像下面的一样:
public final class RegistrationForm extends ActionForm {
ToChinese mychinese = new ToChinese();
得到参数时:
public void setLoginName ( String loginName ) {
this.loginName = mychinese.toChinese( loginName );
}
}
就可以了,跟平常java的中文处理没什么两样

作者 fishandfly1.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。

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:

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> is called <strong>only</strong> if the

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。
如果是gb2312或者其他的什么encoding才需要转化的。
你是不是要实现struts的多语言界面显示?
