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" style="margin-top: 0cm; margin-right: 0cm; margin-bottom: 0pt; margin-left: 0cm; padding: 0px;">????????????<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。

该校验规则文件也是一个标准的校验规则文件。
