在类路径中找不到休眠验证器

Question

我写自定义注释

package ru.tinkoff.bpm.verificationcheckservice.support.validation

import org.hibernate.validator.constraints.CompositionType
import org.hibernate.validator.constraints.ConstraintComposition
import org.hibernate.validator.constraints.URL
import javax.validation.Constraint
import javax.validation.Payload
import javax.validation.ReportAsSingleViolation
import javax.validation.constraints.NotBlank
import kotlin.annotation.AnnotationRetention.RUNTIME
import kotlin.annotation.AnnotationTarget.FIELD
import kotlin.reflect.KClass

@ConstraintComposition(CompositionType.AND)
@URL
@NotBlank
@ReportAsSingleViolation
@Target(FIELD)
@Retention(RUNTIME)
@Constraint(validatedBy = [])
annotation class NotBlankUrl(
    val message: String = "must be not blank and valid URL",
    val groups: Array<KClass<*>> = [],
    val payload: Array<KClass<out Payload>> = []
)

我为 build.gradle.kts

添加依赖

implementation("org.springframework.boot:spring-boot-starter-data-jpa")
implementation("org.springframework.boot:spring-boot-starter-validation")
implementation("org.hibernate:hibernate-validator:7.0.1.Final")

Gradle 在报告中解决 https://scans.gradle.com/s/ddjce3iwnldt4/dependencies?dependencies=valida&expandAll&focusedDependency=WzEsOCwxNDk2LFswLDEsWzE5XV1d

但是当我启动应用程序时我看到错误

The Bean Validation API is on the classpath but no implementation could be found

Action:

Add an implementation, such as Hibernate Validator, to the classpath

为什么 spring 无法识别验证器？

Answer 1

Hibernate Validator 6 及更低版本实现了 Java EE Bean 验证 API。

Hibernate Validator 7 实现了（较新的）Jakarta Bean Validation API，它几乎相同，但 javax.validation 包重命名为 jakarta.validation。

据我所知，Spring 框架仍在使用 Java EE Bean 验证。

所以你所做的是行不通的。消息正确，没有实现 Java EE Bean Validation；只有 Jakarta Bean Validation 的实现，Spring Framework 不支持它。

目前，如果您想使用 Spring Framework，您只能使用 Hibernate Validator 6。

在类路径中找不到休眠验证器

hibernate validator not found in classpath

hibernate-validator

spring-validator

spring-boot
