hibernate - Hibernate Validation Framework 无法加载 javax PersistenceProvider

Question

我正在使用 SpringBoot 版本 2.1.2.RELEASE。作为 spring-boot-starter-web 的一部分，我在类路径中获得了 hibernate-validator:6.0.14.Final 。我也有 spring-boot-starter-data-jpa。

我正在使用验证器来验证服务的输入数据。数据经过验证和处理后，我使用 JPA 存储库将数据保存到 DB。

该应用程序作为战争部署在 Tomcat 服务器上。当我运行应用程序时，我得到以下异常：

看起来它无法找到 PersistenceProvider。

我尝试了以下事情：

1. 如果我禁用验证器，则数据库的持久性工作正常。这意味着它只有验证不起作用。

2. 我检查了 tomcat 类加载日志。我看到以下内容：

   [从文件加载javax.persistence.spi.PersistenceProvider：/app/tomcatprofile/webapps/billing-service/WEB-INF/lib/javax.persistence-api-2.2.jar]

此外，在网上检查错误我发现 javax.persistence.spi.PersistenceProvider 已被弃用。不知道它是如何被验证框架引用的。

我今天尝试的另一件事，如果我将 javax.persistence-api.jar 放在 tomcat lib 目录中，它开始工作正常。
