7.4.2??建立业务控制器
建立一个简单的业务控制器实现类，如代码7.21所示。
代码7.21??AJAX校验示例的业务控制器
?
package?ch7;
import?java.util.Date;
import?com.opensymphony.xwork2.ActionSupport;
public?class?Reg_ajax_Action?extends?ActionSupport?{
????private?String?name;
????private?int?age;
????private?Date?birthday;
????//属性的getter和setter方法
?public?String?getName()?{
????????return?name;
????}
????public?void?setName(String?name)?{
????????this.name?=?name;
????}
????public?int?getAge()?{
????????return?age;
????}
????public?void?setAge(int?age)?{
????????this.age?=?age;
????}
????public?Date?getBirthday()?{
????????return?birthday;
????}
????public?void?setBirthday(Date?birthday)?{
????????this.birthday?=?birthday;
????}
}
?
该Action非常简单，只是定义了3个相应的属性。在配置文件中加入如下内容：
<action name="Reg_ajax_Action" class="ch7.Reg_ajax_Action">
????????????<result name="input">/ch7/reg-ajax.jsp</result>
</action>
7.4.3??建立校验规则文件
建立一个Reg_ajax_Action-validation.xml校验规则文件，如代码7.22所示。
