一、使用@Constraint注解，指定自定义校验类的class
import java.lang.annotation.*;
import io.github.msidolphin.easyvalidator.annotation.Constraint;
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD})
@Constraint(validatedBy = SexValidator.class)
public @interface Sex {
String msg() default ""; // 仅支持msg字段
}二、自定义校验类继承ConstraintValidator抽象类并重写validate方法
import io.github.msidolphin.easyvalidator.constraint.BaseConstraint;
import io.github.msidolphin.easyvalidator.validator.ConstraintValidator;
public class SexValidator extends ConstraintValidator<String> {
@Override
public void validate(String gender, BaseConstraint constraint) {
if (!"male".equals(gender) && !"female".equals(gender)) {
throw new RuntimeException(constraint.getMessage());
}
}
}class Main {
public static void main(String[] args){
User user = new User();
Validator.is(user).get("sex").custom(SexValidator.class);
}
