嵌套注解 @Valid（javax.validation.Valid）

空和非空检查: @Null、@NotNull、@NotBlank、@NotEmpty

Boolean值检查: @AssertTrue、@AssertFalse

长度检查: @Size、@Length

日期检查: @Future、@FutureOrPresent、@Past、@PastOrPresent

其它检查: @Email、@CreditCardNumber、@URL、@Pattern、@ScriptAssert、@UniqueElements

数值检查: @Min、@Max、@Range、@DecimalMin、@DecimalMax、@Digits

SpringBoot自定义配置

只是为了开启快速失败

   @Bean
    public LocalValidatorFactoryBean localValidatorFactoryBean(Environment environment) {
        LocalValidatorFactoryBean factoryBean = new LocalValidatorFactoryBean();
        MessageInterpolatorFactory interpolatorFactory = new MessageInterpolatorFactory();
        factoryBean.setMessageInterpolator(interpolatorFactory.getObject());
        String[] activeProfiles = environment.getActiveProfiles();
        for (String activeProfile : activeProfiles) {
            if ("PRO" .equalsIgnoreCase(activeProfile)) {
                factoryBean.setValidationPropertyMap(Collections
                    .singletonMap(HibernateValidatorConfiguration.FAIL_FAST, Boolean.TRUE.toString()));
                break;
            }
        }
        return factoryBean;
    }

自定义的校验状态(重复注解1.8以下不支持)

import javax.validation.Constraint;
import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
import javax.validation.Payload;
import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Repeatable;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;
import java.util.Objects;

/**

@Repeatable(IsValidState.IsValidStates.class)
@Target({ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = IsValidState.ValidStateValidator.class)
public @interface IsValidState {

    String message() default "无效状态";

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

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

    int[] states();

    class ValidStateValidator implements ConstraintValidator<IsValidState, Number> {

        private IsValidState validState;

        @Override
        public void initialize(IsValidState validState) {
            this.validState = validState;
        }

        @Override
        public boolean isValid(Number value, ConstraintValidatorContext context) {
            if (Objects.isNull(value)) {
                return true;
            }
            int[] states = validState.states();
            for (int state : states) {

                    return true;
                }
            }
            return false;
        }
    }

    @Documented
