标签的，另外，本例子还涉及一个字符编码过滤器的编写及配置，下面是struts的常用标签库：1. <SPAN style="FONT-SIZE: large"><%@ page pageEncoding="UT F-8"%>2. <%@ taglib uri="/tags-bean" prefix="bean" %>3. <%@ taglib uri="/tags-bean-el" prefix="bean -el" %>4. <%@ taglib uri="/tags-html" prefix="html" % >5. <%@ taglib uri="/tags-logic" prefix="logic" % >6. <%@ taglib uri="/tags-logic-el" prefix="logic-el" %>7. <%@ taglib uri="/tags-nested" prefix="neste d" %>表单验证在HelloForm中：/*** Method validate* @param mapping* @param request* @return ActionErrors*/public ActionErrors validate(ActionMapping mapping,HttpServletRequest request) {ActionErrors errors=new ActionErrors();//保存所有错误信息if(name==null||name.trim().length()==0){errors.add("name",new ActionMessage(""));}if(hobby==null||hobby.length<1){errors.add("hobby",newActionMessage("hello.error.hobby"));}if(age<5){errors.add("age",new ActionMessage("hello.error.age",5));}return errors;}/*** Method reset* @param mapping* @param request*/public void reset(ActionMapping mapping, HttpServletRequest request) {age=5;//初始化数据}在包com.struts的文件ApplicationResources.properties添加=\u540D\u5B57\u4E0D\u80FD\u4E3A\u7A7Ahello.error.hobby=\u7231\u597D\u5FC5\u987B\u586B\u5199hello.error.age=\u5E74\u9F84\u4E0D\u80FD\u5C0F\u4E8E5\u5C81效果：提交对象属性提交数据量很大时，我有必要把某些对象的属性在前台用‘对象.属性’的形式进行提交，这样后台不会因为属性多而烦恼。
