Question

我正在使用带有Hibernate的JPA的Spring Boot应用程序，并尝试在WebSphere应用程序服务器7.0.0.33上进行部署。

我包含以下依赖项

有人对此有所了解吗？

Answer 1

这里有两件事：

您无需单独声明Hibernate依赖项。 spring-boot-starter-data-jpa的声明将包含您需要的一切。因此，删除所有手动声明的依赖项，并通过执行mvn dependency:list来验证设置。这应该在类路径上显示JPA 2.1 API JAR，因为Hibernate 4.2.x版本需要JPA 2.1。另外，单独引导Boot应用程序以验证它是否正常工作（使用Spring Data JPA存储库编写集成测试将有效地实现相同的目的）。
部署到WebSphere 7将要求您将ClassLoader层次结构配置为父级，以便类路径查找首先检查应用程序JAR，而不是容器提供的JAR。如果启用了parent-first（并且这是正确的默认值），将首先找到WebSphere发布的JPA JAR（标准7为1.0，带有JPA功能包的7为2.0），并且它们都不适用于最近的Hibernate （因为它需要JPA 2.1）。

Answer 2

WebSphere 7.0内置了JPA 1.0，它不会运行JPA 2.0。对于JPA 2.0，您将需要安装JPA功能包。查看此帖子了解更多详情 - websphere 7 and (application based) open-jpa 2

为什么将Spring Boot应用程序部署到WebSphere 7应用服务器会导致ClassCastException？
