我正在开发 Struts 2 应用程序，试图为 10 位数字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是否有任何方式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 {

public void setDob(String dob) {
this.dob = dob;

最佳答案
使用 stringlenth validator 可以验证字符串的长度。检查stringlength validator .
并且使用date validator ，您可以验证日期格式。检查date validator .
如果您想使用 validate() 验证日期时间选择器，您应该使用逻辑来解析选择器返回的值，如果您没有使用 SimpleDateFormat其他日期时间库，如 JODA并且不关心时区，那么您应该为日期时间创建 ThreadLocal 解析器。
