struts实现多国语言切换
1 准备资源文件。
资源文件命名格式：filename_language_country.properties.
中文文件名为index_zh_cn.properties。
日文文件名为 index_ja_jp.properties。
英文文件名为 index_en.properties。
英文文件内容：
index.jsp.welcome=colimas library management system
index.jsp.name=name
index.jsp.userid=user id
index.jsp.pass=password
中文文件内容：
index.jsp.welcome=\u4f60\u597d
index.jsp.name=\u59d3\u540d
index.jsp.userid=\u7528\u6237\u540d
index.jsp.pass=\u5bc6\u7801
日文文件内容：
index.jsp.welcome=\u3044\u3089\u3063\u3057\u3083\u3044\u307e\u305b
index.jsp.name=\u59d3\u540d
index.jsp.userid=\u30e6\u30fc\u30b6\u30fcid
index.jsp.pass=\u30d1\u30b9\u30ef\u30fc\u30c9
\uxxxx是中文被转换后的ascii码。可以使用native2ascii.exe工具转换。
2 struts-config.xml里配置资源文件 <message-resources parameter="resources.config.index" />
resources.config.index是classes目录下的resources/config子目录的index__xx_xx.properties文件.
struts根据你的浏览器的语言设置调用不同语言的资源文件。
例如：如果你的ie默认语言为中文则。
struts将使用index_zh_cn.properties。而在
struts-config.
xml里只需写出“index”即可

jsp.welcome属性
selectlanguageaction.do调用action实现语言转换。

string lan=myform.getlanguage();
switch((new integer(lan)).intvalue()){
case 0 :
request.getsession().setattribute(globals.locale_key,locale.china);
break;
case 1:
request.getsession().setattribute(globals.locale_key, locale.japan);
break;
case 2:
request.getsession().setattribute(globals.locale_key, locale.english);
break;
default:
request.getsession().setattribute(globals.locale_key, locale.english);
break;
}
return mapping.findforward("index");
}
}
form
/*

* window - preferences - java - code style - code templates
*/
package com.nova.colimas.web.form;
import org.apache.struts.action.actionform;
/**
* @author tyrone
**/
public class selectlanguageform extends actionform {
private string language;
public void reset() {
this.language="";
return;
}
/**
* @return returns the language.
*/
public string getlanguage() {
return language;
}
/**
* @param language the language to set.
*/
public void setlanguage(string property1) {
this.language = property1;
}
}
结果1 ie默认语言为中文：
启动画面
切换为日语
切换为英文
