俺才学习STRUTS碰到中文问题,研究了一整天,在网上狂搜一通,整理一下成果给大家分享!不足处大家能指正,谢谢!
STRUTS资源文件中文字符集问题
native2ascii -encoding GBK F:\myStruts\src\mystruts\ApplicationResources.properties F:\myStruts\src\mystruts\ApplicationResources_zh_CN.properties将原有的资源文件转换成GBK码。并在WEB.XML文件中加入以下代码(红色部分):
<?xml version="1.0" encoding="GBK"?>

STRUTS中文问题
解决办法1:(未实现)
jakarta-struts-1.0.2-src\src\share\org\apache\struts\util\PropertyMessageResources.java
将第289行的:messages.put(messageKey(localeKey, key),props.getProperty(key));
改成下面的代码:
String sProps = props.getProperty(key);
try
{
sProps = new String(sProps.getBytes("ISO-8859-1"),"GBK");
}
catch (Exception e)
{
e.printStackTrace();
}
messages.put(messageKey(localeKey, key),sProps);
编译后替换原有STRUTS.JAR中的PropertyMessageResources类。
解决办法2:
在工程中加入2个类filters.RequestDumperFilter、filters.SetCharacterEncodingFilter(C:\Program Files\Apache Software Foundation\Tomcat 5.0\webapps\jsp-examples\WEB-INF\classes\filters),修改WEB.XML代码(红色部分)如下:
<?xml version="1.0" encoding="GBK"?>

解决办法3:
对于处理 Struts Framework 中文编码问题有多种方式,在此我们尝试继承 ActionServlet 类并覆盖 process 方法,于子类process 方法中设定请求编码。由此展现ActionServlet 扮演前端Controller 之特质。
首先,点击选择 JBuilder 主菜单 File | New Classes 准备产生一新的类。并继承自org.apache.struts.action.ActionServlet
并将预设的类名称由Untitled1 改为GBKActionServlet。按下 OK 按钮后即产生程序代码。点击选择 JBuilder 主菜单Wizards | Override Methods… 激活覆盖方法精灵,覆盖方法精灵会自动列出父类 ActionServlet 所有可供覆盖之方法。您可于 Available methods 清单方块中选取process (HttpServletRequest request, HttpServletResponseresponse) 方法,完成后按下 OK 按钮。此时我们可修改覆盖后 process 方法程序代码如下:request.setCharacterEncoding ("GBK") ;super.process (request, response) ;
首行程序代码将 process 传入之参数 request 设定为 GBK编码,其余行为同父类。接下来我们将要修改 web.xml部署描述档,以指定 Servlet 之进入点,首先点击选择左上方项目窗格中的 web.xml。此时,左下方结构窗格将出现 web.xml 内 XML 标记之树状结构。您可以点击选择 Servlets 内的 Action 项目。
您可以按下 Servlet class 项目右方 [ … ] 按钮选取新的进入点替换预设之ActionServlet,也就是之我们撰写之util. GBKActionServlet。倘若您非常熟悉 web.xml 结构,同样地可以直接点击选择内容窗格内的 Sources 页次,直接以文字编辑器修改 <servlet-class> 标记的内容。web.xml代码如下:<?xml version="1.0" encoding="UTF-8"?>
