ClassCastException InjectedDataSourceConnectionProvider Spring 3.1.0，Hibernate 4，JPA EntityManagerFactory

Question

使用：

• 春季 3.1.0
• 休眠 4
• JPA 2
• GWT 2.3.0。

[类似于Exception in GWT Dev Mode + Spring 3.1 + Hibernate 4.0.1]

当运行一个非常简单的 GWT 应用程序（使用 Greeting Service）并向应用程序添加 spring 配置（通过 web.xml 和相关的 spring 配置文件）时，在 gwt dev 模式下启动系统时会出现异常（从 Eclipse 内部和命令行 (mvn gwt:run))。

异常如下图：

[警告] 嵌套在 org.springframework.beans.factory.BeanCreationException：在 ServletContext 资源 [/WEB-INF/classes/spring-main-config.xml] 中定义名称为“jgkgwtclasscastissueEntityManagerFactory”的 bean 创建错误：调用 init方法失败；嵌套异常是 javax.persistence.PersistenceException：[PersistenceUnit：jgkgwtclasscastissue-PU] 无法构建 EntityManagerFactory：java.lang.ClassCastException：org.hibernate.ejb.connection.InjectedDataSourceConnectionProvider 无法转换为 org.hibernate.service.jdbc.connections。 spi.ConnectionProvider

目前还不清楚问题出在哪里。有什么建议吗？

Answer 1

在这里发现同样的问题：Exception in GWT Dev Mode + Spring 3.1 + Hibernate 4.0.1

它来自 Hibernate 上的类加载器问题，该问题似乎与 GWT/jetty shell 模式不兼容。该错误仍然在 Hibernate 上打开，但您可以应用补丁（请参阅https://hibernate.onjira.com/browse/HHH-7084）

Answer 2

我记得有时会遇到同样的问题，在我的 lib/ 中，我有 ejb3-persistence.jar，它与升级到 hibernate 4 和 Spring 引入的 hibernate-jpa-2.0-api-1.0.1.Final.jar 冲突3.1.1，我去掉了ejb3-persistence.jar，javax.persistence.PersistenceException: [PersistenceUnit: jgkgwtclasscastissue-PU] Unable to build EntityManagerFactory: java.lang.ClassCastException被排序了。

尝试最早版本的 Hibernate (3.3) 和 Spring (3.0.7)。很多时候，不可能同时使用最新版本 - 会出现神奇的异常。
