Hibernate 作为 TomEE 7 中的 JPA 提供者和 Bean Validator

Question

JPA

在this Article (TomEE 7 and Hibernate 5.2 persistence.xml) 中将 Hibernate 5.2 配置为 Apache Tomcat (TomEE)/8.5.11 (7.0.3) 中的 JPA 实现者

Bean 验证

要将 Hibernate Validator 实现为 Bean Validator，将 hibernate-validator-5.4.0.Final.jar、hibernate-validator-annotation-processor-5.4.0.Final.jar、hibernate-validator-cdi-5.4.0.Final.jar 放在 /lib 文件夹中并删除 bval-core-1.1.2.jar、bval-jsr-1.1.2.jar

但是在部署 webapp 时出现以下错误：

这个问题怎么解决？？？？

Answer 1

如 Hibernate Validator 文档 (here) 中所述，如果应用程序在不提供开箱即用的 CDI 集成的环境中运行，您可以通过添加 hibernate-validator-cdi 来使用 Hibernate Validator CDI 可移植扩展

Apache Tomcat (TomEE)/8.5.11 (7.0.3) 使用开箱即用的 Apache OpenWebBeans 实现 CDI。

从<TomEE>/lib 文件夹中删除hibernate-validator-cdi-5.4.0.Final.jar 后问题已解决。

Answer 2

认为它来自您包含 hibernate-validator 的事实，您可以在 application.properties (WEB-INF) 或 conf/system.properties (global) 中设置解决方法：

org.apache.bval.cdi.BValExtension.active=false
