上述问题仅在字段验证期间存在。我该如何解决这个问题？谢谢你的任何建议..

Answer 1

由于可能存在依赖关系版本的冲突，所提到的错误正在发生。

WildFly已在＆lt; wildfly_dir＆gt; \ modules \ system \ layers \ base \ org \ hibernate <中提供 hibernate-core 和 hibernate-validator 依赖项/ em>的

对于WildFly10，依赖关系＆＃39;版本如下：

hibernate-core-5.0.7.Final

hibernate-validator-5.2.3.Final

因此，在 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>

但如果你想提供自己的依赖关系，如WildFly 10 documentation所述，你应该提供一个 jboss-deployment-structure.xml ，你基本上告诉WildFly忽略它＆＃ 39;自己的依赖：

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

这样，容器将加载随应用程序打包并存在于WAR的 WEB-INF / lib 文件夹中的依赖项。

修改

在转到PersistenceUtilHelper.isLoadedWithoutReference的{{3}}后，人们注意到，在Hibernate 5.1中，它不再引用错误发生在第119行的类FieldInterceptionHelper。而在版本5.0中source code。

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>

Answer 2

以下对我有用：

hibernate-core-5.1.0.Final
hibernate-entitymanager-5.1.0.Final
hibernate-validator-5.2.4.Final

java.lang.ClassNotFoundException：org.hibernate.bytecode.instrumentation.internal.FieldInterceptionHelper
