设置简单 Spring MVC、EclipseLink、Wildfly、Maven 项目

Question

我想用 Maven 构建一个 Spring MVC webapp，它使用 EclipseLink 作为 JPA 提供程序并在 Wildfly 应用程序服务器上使用运行s。不幸的是，我无法做到运行。我想使用所有的最新版本。

当我尝试运行 Wildfly 8.2 或 Tomcat 8 上的网络应用程序时出现以下错误：

01:25:11,648 WARN [org.springframework.web.context.support.XmlWebApplicationContext] (MSC service thread 1-1) Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException:

Error creating bean with name 'emf' defined in ServletContext resource [/WEB-INF/spring-servlet.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException:

Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.6.0.v20150309-bf26070): org.eclipse.persistence.exceptions.EntityManagerSetupException Exception Description: Predeployment of PersistenceUnit [MovieTime] failed.

Internal Exception: Exception [EclipseLink-28010] (Eclipse Persistence Services - 2.6.0.v20150309-bf26070): org.eclipse.persistence.exceptions.EntityManagerSetupException Exception Description: PersistenceUnitInfo MovieTime has transactionType JTA, but does not have a jtaDataSource defined.

A 在 Google 上搜索了很多，但没有找到任何有用的信息。我认为 persistence.xml 或 pom.xml 中缺少某些内容，但我不知道是什么。 The whole exception is here.

Here is the file hierarchy of my project. (I cannot share image on SO yet)

我没有打开实体包，因为我有大约 30 个从数据库表生成的实体。

这是我的 pom.xml:

好的，我通过将交易类型更改为 RESOURCE_LOCAL 解决了这个错误。
