1，动态属性表单 DynaActionForm
所有变量在struts-config.xml中配置：
    <form-bean name="dynaTestForm" type="org.apache.struts.action.DynaActionForm">
      <form-property name="age" type="java.lang.Integer" initial="18"/>
      <form-property name="name" type="java.lang.String" initial="" />
      <form-property name="birthday" type="java.sql.Date" initial=""/>
    </form-bean>
2，Action中获取动态属性
DynaTestAction.java
public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  DynaActionForm dynaTestForm = (DynaActionForm) form;
  Integer age = (Integer)dynaTestForm.get("age");
  String name = (String)dynaTestForm.get("name");
  Date birthday = (Date)dynaTestForm.get("birthday");
  return mapping.getInputForward(); //返回输入页面
}
3,JSP中使用动态属性
  <HTML:form action="/dynaTest">
   age : <html:text property="age"/><html:errors property="age"/><br/>
   name : <html:text property="name"/><html:errors property="name"/><br/>
   birthday : <html:text property="birthday"/><html:errors property="birthday"/><br/>
   <html:submit/><html:cancel/>
  </html:form>
