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>> = []
)

我添加了 build.gradle.kts 的依赖项

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 在报告中解决它 https://scans.gradle.com/s/ddjce3iwnldt4/dependency?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不识别验证器？

Answer 1

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

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

据我所知，Spring Framework 仍在使用 Java EE Bean Validation。

所以你所做的事情是行不通的。该消息是正确的，您的类路径中没有Java EE Bean Validation 的实现；只是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。
