java struts2 国际化配置

1.struts.properties
struts.custom.i18n.resources=language.message,language.bizMessage,language.format,language.messages,language.language
struts.objectFactory =spring
struts.objectFactory.spring.autoWire =type
struts.ui.theme=simple
struts.locale=zh_CN
struts.i18n.encoding=UTF-8
struts.configuration.xml.reload=false
struts.multipart.parser=jakarta
struts.multipart.maxSize=100000000
struts.devMode=true
2.配置文件名称必须以language.*  ------*.properties格式开头；



3.页面添加切换按钮

function changeLocalKey(localKey){
$.ajaxSettings.async = false;
$.getJSON(getContextPath()
+ '/common/changeLocalKey.action?random=' + Math.random(),
{
        "localKey" :localKey  //参数设定
}, function(data) {
window.location.reload();
});
}

4.java中action
/**
* 国际化语言选择
*
* @param email
* @return
*/
public String changeLocalKey() throws Exception {
    Locale currentLocable=null;
if(StringUtils.isNotEmpty(localKey)){
if(localKey.equals("chinese")){
currentLocable=new Locale("zh", "CN");
}
            if(localKey.equals("english")){
            currentLocable=new Locale("en", "US");
}
if(localKey.equals("japanese")){
currentLocable=new Locale("ja", "JP");
}
}
else{
currentLocable=Locale.getDefault();
}
ActionContext.getContext().setLocale(currentLocable);
Envir.getSession().setAttribute("WW_TRANS_I18N_LOCALE", currentLocable);
return SUCCESS;
}
5.如果初始化需要默认自定义语言添加如下配置 web.xml
<filter-mapping> 
        <filter-name>i18nFilter</filter-name> 
        <url-pattern>*.action</url-pattern> 
</filter-mapping>
<filter> 
       <filter-name>i18nFilter</filter-name> 
        <filter-class>com.canon.shwg.core.interceptor.I18nFilter</filter-class> 
</filter>
