搭建简单的 Spring MVC、EclipseLink、Wildfly、Maven 项目答案

【问题标题】：Setup of simple Spring MVC, EclipseLink, Wildfly, Maven project搭建简单的 Spring MVC、EclipseLink、Wildfly、Maven 项目
【发布时间】：2015-04-01 00:08:07
【问题描述】：

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 应用程序服务器上运行。不幸的是，我无法让它运行。我想使用所有东西的最新版本。

当我尝试在 Wildfly 8.2 或 Tomcat 8 上运行 webapp 时出现以下错误：

01:25:11,648 警告 [org.springframework.web.context.support.XmlWebApplicationContext] （MSC 服务线程 1-1）上下文期间遇到异常初始化 - 取消刷新尝试： org.springframework.beans.factory.BeanCreationException：

在 ServletContext 资源中创建名称为“emf”的 bean 时出错 [/WEB-INF/spring-servlet.xml]：init方法调用失败；嵌套异常是 javax.persistence.PersistenceException:

异常 [EclipseLink-28018]（Eclipse 持久性服务 - 2.6.0.v20150309-bf26070）：org.eclipse.persistence.exceptions.EntityManagerSetupException 异常描述：PersistenceUnit [MovieTime] 的预部署失败了。

内部异常：异常 [EclipseLink-28010]（Eclipse 持久性服务 - 2.6.0.v20150309-bf26070）： org.eclipse.persistence.exceptions.EntityManagerSetupException 异常说明：PersistenceUnitInfo MovieTime 有 transactionType JTA，但没有定义 jtaDataSource。

谷歌搜索了很多，但我没有发现任何有用的信息。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：

【问题讨论】：

如异常中所述，您需要在persistence.xml文件的中提供一个元素，并在应用程序中配置数据源的名称服务器。您可以参考docs.oracle.com/javaee/7/tutorial/persistence-intro003.htm 的 Java EE 教程
或者，您可以将 transaction-type 切换为 RESOURCE_LOCAL 并在 persistence.xml 中提供与数据库的连接，这已在您的文件中实现。
目前我没有足够的时间来开发这个应用程序。一旦我可以继续，我会发布一个回答。谢谢佩特罗斯！

【解决方案1】：

好的，我通过将事务类型更改为 RESOURCE_LOCAL 解决了这个错误。
