1、設置接口

@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、編寫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>* 判斷18位身份證的合法性* </p>* 根據〖中華人民共和國國家標準GB11643-1999〗中有關公民身份號碼的規定，公民身份號碼是特征組合碼，由十七位數字本體碼和一位數字校驗碼組成。* 排列順序從左至右依次為：六位數字地址碼，八位數字出生日期碼，三位數字順序碼和一位數字校驗碼。* <p>* 順序碼: 表示在同一地址碼所標識的區域范圍內，對同年、同月、同 日出生的人編定的順序號，順序碼的奇數分配給男性，偶數分配 給女性。* </p>* <p>* 1.前1、2位數字表示：所在省份的代碼； 2.第3、4位數字表示：所在城市的代碼； 3.第5、6位數字表示：所在區縣的代碼；* 4.第7~14位數字表示：出生年、月、日； 5.第15、16位數字表示：所在地的派出所的代碼； 6.第17位數字表示性別：奇數表示男性，偶數表示女性；* 7.第18位數字是校檢碼：也有的說是個人信息碼，一般是隨計算機的隨機產生，用來檢驗身份證的正確性。校檢碼可以是0~9的數字，有時也用x表示。* </p>* <p>* 第十八位數字(校驗碼)的計算方法為： 1.將前面的身份證號碼17位數分別乘以不同的系數。從第一位到第十七位的系數分別為：7 9 10 5 8 4 2 1* 6 3 7 9 10 5 8 4 2* </p>* <p>* 2.將這17位數字和系數相乘的結果相加。* </p>* <p>* 3.用加出來和除以11，看余數是多少？* </p>* 4.余數只可能有0 1 2 3 4 5 6 7 8 9 10這11個數字。其分別對應的最后一位身份證的號碼為1 0 X 9 8 7 6 5 4 3 2。* <p>* 5.通過上面得知如果余數是2，就會在身份證的第18位數字上出現羅馬數字的Ⅹ。如果余數是10，身份證的最后一位號碼就是2。* </p>** <p>* 對于15位身份證,不需要判斷最后一位驗證碼,最后一位代表性別，奇數表示男性，偶數表示女性 默認使用18位身份證號，15位也支持* </p>** @author rooseek***/ public class
