上述问题仅在字段验证时存在。我该如何解决这个问题？感谢您的任何建议..

Answer 1

所提到的错误是由于依赖版本可能存在冲突而发生的。

WildFly 已经在 \modules\system\layers\base\org\hibernate 中提供了 hibernate-core 和 hibernate-validator 依赖项em>.

在 WildFly10 的情况下，依赖项的版本如下:

• hibernate-core-5.0.7.Final
• hibernate-validator-5.2.3.Final

因此，在您的 pom.xml 上，您可以按照提供的方式放置 Hibernate 依赖项，并让容器使用它自己的:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.1.0.Final</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-validator</artifactId>
    <version>5.2.4.Final</version>
    <scope>provided</scope>
</dependency>

但是如果您想提供自己的依赖项，如 WildFly 10 documentation 中所述，你应该提供一个 jboss-deployment-structure.xml，你基本上告诉 WildFly 忽略它自己的依赖关系:

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="org.hibernate" slot="main" />
        </exclusions>
    </deployment>
</jboss-deployment-structure>

这样，容器将加载与您的应用程序一起打包并且存在于您的 WAR 的 WEB-INF/lib 文件夹中的依赖项。

编辑

转到source code之后在 PersistenceUtilHelper.isLoadedWithoutReference 中，人们注意到，在 Hibernate 5.1 中，它不再引用类 FieldInterceptionHelper，在第 119 行发生错误。而在 5.0 版中它是 still does .

我还建议您添加最新版本的 hibernate-entitymanager 依赖项，以便与其他 Hibernate 依赖项保持一致:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.1.0.Final</version>
</dependency>
