大陆居民身份证验证方法（java）
1、设置接口
@Constraint(validatedBy = ChineseIdNumberValidator.class) @Target({ElementType.METHOD, ElementType.FIELD, ElementType.PARAMETER}) @Retention(RetentionPolicy.RUNTIME) @Documented public @interface IdNumber { String message() default "{common.IdNumber.Pattern}"; Class<?>[] groups() default {}; Class<? extends Payload>[] payload() default {}; }
2、编写Validator
import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Calendar; import java.util.Date; import java.util.GregorianCalendar; import java.util.HashMap; import java.util.Map; import java.util.logging.Level; import java.util.logging.Logger; import javax.validation.ConstraintValidatorContext; /** * * <p> * 判断18位身份证的合法性 * </p> * 根据〖中华人民共和国国家标准GB11643-1999〗中有关公民身份号码的规定，公民身份号码是特征组合码，由十七位数字本体码和一位数字校验码组成。 * 排列顺序从左至右依次为：六位数字地址码，八位数字出生日期码，三位数字顺序码和一位数字校验码。 * <p> * 顺序码: 表示在同一地址码所标识的区域范围内，对同年、同月、同 日出生的人编定的顺序号，顺序码的奇数分配给男性，偶数分配 给女性。 * </p> * <p> * 1.前1、2位数字表示：所在省份的代码； 2.第3、4位数字表示：所在城市的代码； 3.第5、6位数字表示：所在区县的代码； * 4.第7~14位数字表示：出生年、月、日； 5.第15、16位数字表示：所在地的派出所的代码； 6.第17位数字表示性别：奇数表示男性，偶数表示女性； * 7.第18位数字是校检码：也有的说是个人信息码，一般是随计算机的随机产生，用来检验身份证的正确性。校检码可以是0~9的数字，有时也用x表示。 * </p> * <p> * 第十八位数字(校验码)的计算方法为： 1.将前面的身份证号码17位数分别乘以不同的系数。从第一位到第十七位的系数分别为：7 9 10 5 8 4 2 1 * 6 3 7 9 10 5 8 4 2 * </p> * <p> * 2.将这17位数字和系数相乘的结果相加。 * </p> * <p> * 3.用加出来和除以11，看余数是多少？ * </p> * 4.余数只可能有0 1 2 3 4 5 6 7 8 9 10这11个数字。其分别对应的最后一位身份证的号码为1 0 X 9 8 7 6 5 4 3 2。 * <p> * 5.通过上面得知如果余数是2，就会在身份证的第18位数字上出现罗马数字的Ⅹ。如果余数是10，身份证的最后一位号码就是2。 * </p> * * <p> * 对于15位身份证,不需要判断最后一位验证码,最后一位代表性别，奇数表示男性，偶数表示女性 默认使用18位身份证号，15位也支持 * </p> * * @author rooseek * * */ public class ChineseIdNumberValidator implements ConstraintValidator { private final static Map<String, String> code2Province = new HashMap<String, String>() { private static final long serialVersionUID = 1L;
