   4、利用struts默认把Locale放到session中的特性，可以采用编程的方式手动切换语言设置 参见：ChangeLanguageAction.java public class LangAction extends Action { @Override public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { Locale l=null; //Locale locale = Locale.getDefault(); String lang=request.getParameter("lang"); if("cn".equals(lang)){ l=new Locale("zh","CN"); }else if("en".equals(lang)){ l=new Locale("en","US"); } //request.getSession().setAttribute(Globals.LOCALE _KEY, l); this.setLocale(request, l); return mapping.findForward("success"); } } ------------------------------------- jstl             ：

">    消息文本的国际化，分为三个步骤： * 创建消息 * 传递消息 * 显示消息 public class LoginAction extends Action {@Override public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { LoginActionForm laf = (LoginActionForm)form; String username = laf.getUsername(); String password = laf.getPassword();ActionMessages messages = new ActionMessages(); try { UserManager.getInstance().validate(username, password); //创建国际化消息文本 ActionMessage message = new ActionMessage("user.login.success", username); //ActionMessage message = new ActionMessage("user.login.success", new Object[]{username}); messages.add("loginSuccess1", message); messages.add("loginSuccess2", message); //传递国际化消息文本 this.saveMessages(request, messages); return mapping.findForward("success"); }catch(UserNotFoundException unfe) { //创建国际化消息文本 ActionMessage message = new ActionMessage("user.not.found", username); messages.add("error1", message); //传递国际化消息文本 this.saveErrors(request, messages); }catch(PasswordErrorException pee ) { //创建国际化消息文本 ActionMessage message = new ActionMessage("user.password.error"); messages.add("error2", message); //传递国际化消息文本 this.saveErrors(request, messages); } //return mapping.findForward("error"); return mapping.getInputForward(); }} 如何创建消息？ * 理解ActionMessage和ActionMessages的区别如何传递消息？ * 理解saveMessages和saveErrors的区别如何显示消息？ * 通过标签显示消息（可以显示提示消息和错误消息，既能读取MESSAGE_KEY也能读取ERROR_KEY）           -----------------------    * 通过标签显示消息（只能显示错误消息），只能读取ERROR_KEY  -----------------------------
