校验规则

package com.XX.assess.util;import cn.hutool.core.util.StrUtil;
import com.XX.assess.annotation.Mobile;import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;/*** 自定义校验规则* @author super*/
public class MobileValidator implements ConstraintValidator<Mobile,String> {/*** 是否必填，默认不必填*/private boolean required = false;/*** 初始化，获取是否必填* @param constraintAnnotation*/@Overridepublic void initialize(Mobile constraintAnnotation) {required = constraintAnnotation.required();}/*** 判断是否校验手机号* @param value* @param context* @return*/@Overridepublic boolean isValid(String value, ConstraintValidatorContext context) {// 必填，则去校验手机号格式if (required){return ValidatorUtil.Mobile(value);}else {// 如果不必填，手机号为空，返回tureif (StrUtil.isEmpty(value)){return true;}else {// 否则校验手机号格式return ValidatorUtil.Mobile(value);}}}
}

校验方法

package com.XX.assess.util;import cn.hutool.core.util.StrUtil;import java.util.regex.Matcher;
import java.util.regex.Pattern;/*** @author 校验工具类*/
public class ValidatorUtil {private static final Pattern mobile_pattern = Pattern.compile("[1]([3-9])[0-9]{9}$");public static boolean Mobile(String mobile) {if (StrUtil.isEmpty(mobile)){return false;}Matcher matcher = mobile_pattern.matcher(mobile);return matcher.matches();}
