我正在开发 Struts 2 应用程序，试图为 10 位数的手机号码提供验证。

我只允许 10 位数字，但即使我输入 10 位数字，它仍然显示验证错误消息，并且还想知道有什么方法可以购买我们可以对日期时间选择器 DOJO 标签执行验证。

在我的 bean 类中它是long类型

package model;


public class Empmodel {
private String firstname;

    return dob;

    this.dob = dob;

使用stringlenth验证器可以验证字符串的长度。检查字符串长度验证器。

并且使用date验证器可以验证日期格式。检查日期验证器。

如果您想使用验证日期时间选择器，validate()您应该使用解析选择器返回的值的逻辑，SimpleDateFormat如果您不使用其他日期时间库（如JODA）并且不关心时区，那么您应该ThreadLocal为日期时间创建解析器。
