就是想试一下自定义的注解

一个简单的springboot工程

浏览器发请求后，http://localhost:9999/savePhone?phone=123

没有任何错误产生，校验实现的断点都没走

why？？？？

自定义注解，校验电话号

@Documented
@Constraint(validatedBy = PhoneValidator.class)
@Retention(RetentionPolicy.RUNTIME)
@Target({METHOD, TYPE, ANNOTATION_TYPE, CONSTRUCTOR, FIELD, PARAMETER})
public @interface Phone {

    String message() default "电话号格式错误";

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

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

}

电话号校验实现，电话号必须有长度，必须是数字，长度为11位

@Component
public class PhoneValidator implements ConstraintValidator<Phone, String> {

    @Override
    public boolean isValid(String content, ConstraintValidatorContext constraintValidatorContext) {
        return StringUtils.hasLength(content) && NumberUtil.isNumber(content) && content.length() == 11;
    }
}

controller

@Validated
@RestController
public class ValidationController {

    @GetMapping("/savePhone")
    public R<String> savePhone(@RequestParam("phone") @Phone(message = "请检查电话号！") String phone) {

        return R.success();
    }
}
