自定义注解

/**
 * 手机号校验
 */
@Target({ElementType.FIELD, ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@Constraint(validatedBy = {MobilePhoneValidator.class})
public @interface MobilePhoneValid {

    String message() default "手机格式异常";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

校验规则

/**
 * @Description 手机校验
 */
@Slf4j
public class MobilePhoneValidator implements ConstraintValidator<MobilePhoneValid, String> {


    private static final int PHONE_LENGTH =11;

    private static final Pattern pattern = Pattern.compile("^[1]\\d{10}#34;);

    @Override
    public boolean isValid(String phone, ConstraintValidatorContext context) {
        if(StrUtil.isBlank(phone)){
            log.warn("MolbiePhoneValidator phone is blank, phone = {}", phone);
            return false;
        }

        if(phone.length() != PHONE_LENGTH){
            log.warn("MolbiePhoneValidator phone length valid fail, phone = {}", phone);
            return false;
        }


        if(!pattern.matcher(phone).matches()){
            log.warn("MolbiePhoneValidator phone pattern valid fail, phone = {}", phone);
            return false;
        }

        return true;
    }
}

使用

    /**
     *  账号
     */
    @MobilePhoneValid
    private String account;

备注：利用@Constraint注解，大家可以举一反三。
