JAVA国际化的实现
JAVA国际化的实现的国际化由两部分组成：
（１）页面国际化处理
（２）ＪＡＶＡ类的源代码处理
一、给如下资源文件添加需要国际化的内容
1、ApplicationResources.properties
ApplicationResources_zh_CN.properties 中文
ApplicationResources_en_US.properties 英文
2、ApplicationResources.properties
ApplicationResources_zh_CN.properties 中文
ApplicationResources_en_US.properties 英文
二、在strutis.xml文件中作如下配置
<message-resources parameter="resources.activetitle.ApplicationResources"/>
<message-resources parameter="resources.menutitle.GlobalUITitle" key='globaluititle'/>
<message-resources parameter="resources.menutitle.UITitle" key='uititle'/>
<message-resources parameter="resources.menutitle.MenuTitle" key='menutitle'/> <message-resources parameter="resources.activetitle.ApplicationResources"></message-resources>
三、写Constants类里写处理资源文件及国际化的方法，主要用于在JAVA源代码中处理国际化问题
该类如下：
public class Constants {
public static MessageResources MESSAGE = MessageResources.getMessageResources("Reseveinfo");
public static MessageResources MESSAGE_UITITLE_RES = MessageResources
.getMessageResources("resources.menutitle.UITitle");
public static MessageResources MESSAGE_GLOBAL_RES = MessageResources
.getMessageResources("resources.menutitle.GlobalUITitle");
public static MessageResources MESSAGE_MENU_RES = MessageResources
.getMessageResources("resources.menutitle.MenuTitle");
public static MessageResources MESSAGE_APP_RES = MessageResources
.getMessageResources("resources.activetitle.ApplicationResources");
public static String [] disposeLanguage(Locale locale){
String []pagesign = new String[6];
pagesign[0] = MESSAGE_APP_RES.getMessage(locale, "pages.first");
pagesign[1] = MESSAGE_APP_RES.getMessage(locale, "pages.previous");
pagesign[2] = MESSAGE_APP_RES.getMessage(locale, "pages.next");
pagesign[3] = MESSAGE_APP_RES.getMessage(locale, "pages.end");
pagesign[4] = MESSAGE_APP_RES.getMessage(locale, "pages.no");
pagesign[5] = MESSAGE_APP_RES.getMessage(locale, "pages.page");
return pagesign;
}
// 处理语言国际化
public static String disposeLanguageApp(Locale locale,String str,Object [] args){
String retStr="";
if(locale == null || StringUtils.isEmpty(str))
return retStr;
if(args == null){
retStr=MESSAGE_APP_RES.getMessage(locale,str);
}else{
retStr=MESSAGE_APP_RES.getMessage(locale,str,args);
}
retStr=StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
// 处理语言国际化
public static String disposeLanguageApp(Locale locale,String str){
String retStr = "";
if (locale == null || StringUtils.isEmpty(str))
return retStr;
retStr = MESSAGE_APP_RES.getMessage(locale, str);
retStr = StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
// 处理语言国际化
public static String disposeLanguageUititle(Locale locale,String str,Object [] args){
String retStr="";
if(locale == null || StringUtils.isEmpty(str))
return retStr;
if(args == null){
retStr=MESSAGE_UITITLE_RES.getMessage(locale,str);
}else{
retStr=MESSAGE_UITITLE_RES.getMessage(locale,str,args);
}
retStr=StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
// 处理语言国际化
public static String disposeLanguageUititle(Locale locale,String str){
String retStr = "";
if (locale == null || StringUtils.isEmpty(str))
return retStr;
retStr = MESSAGE_UITITLE_RES.getMessage(locale, str);
retStr = StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
// 处理语言国际化
public static String disposeLanguageGlobal(Locale locale,String str,Object [] args){
String retStr="";
if(locale == null || StringUtils.isEmpty(str))
return retStr;
if(args == null){
retStr=MESSAGE_GLOBAL_RES.getMessage(locale,str);
}else{
retStr=MESSAGE_GLOBAL_RES.getMessage(locale,str,args);
}
retStr=StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
// 处理语言国际化
public static String disposeLanguageGlobal(Locale locale,String str){
String retStr = "";
if (locale == null || StringUtils.isEmpty(str))
return retStr;
retStr = MESSAGE_GLOBAL_RES.getMessage(locale, str);
retStr = StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
// 处理语言国际化
public static String disposeLanguageMenu(Locale locale,String str,Object [] args){
String retStr="";
if(locale == null || StringUtils.isEmpty(str))
return retStr;
if(args == null){
retStr=MESSAGE_MENU_RES.getMessage(locale,str);
}else{
retStr=MESSAGE_MENU_RES.getMessage(locale,str,args);
}
retStr=StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
// 处理语言国际化
public static String disposeLanguageMenu(Locale locale,String str){
String retStr = "";
if (locale == null || StringUtils.isEmpty(str))
return retStr;
retStr = MESSAGE_MENU_RES.getMessage(locale, str);
retStr = StringUtils.isEmpty(retStr) ? "" : retStr;
return retStr;
}
}
//===========================================================================================
例如：在JAVA源代码中处理国际化问题
ui.title.log.page.usercode=用户代码
Constants.disposeLanguageUititle(locale,"ui.title.log.page.usercode"))); //"用户代码"
四、处理JSP页面的国际化问题
ui.title.order.orderid=订单号
<bean:message key="ui.title.order.orderid" bundle="uititle"/>
<bean:message bundle="uititle" key="ui.title.order.orderid"> <!----></bean:message>
注：在标签 <bean:message 中的bundl属性的值是<message-resources parameter="resources.menutitle.UITitle" key='uititle'/>
中的 key值
<message-resources key="uititle" parameter="resources.menutitle.UITitle"></message-resources>
