我想用Maven構建一個Spring MVC webapp，它使用EclipseLink作爲JPA提供程序並在Wildfly應用程序服務器上運行。不幸的是，我無法讓它運行。我想使用最新版本的一切。設置簡單的Spring MVC，EclipseLink，Wildfly，Maven項目
我收到以下錯誤，當我嘗試在Wildfly 8.2或Tomcat運行8 web應用程序：
01：25：11648 WARN [org.springframework.web.context.support.XmlWebApplicationContext ] （MSC服務線程1-1）例外情況下過程中遇到的 初始化 - 取消刷新嘗試： org.springframework.beans.factory.BeanCreationException：

A谷歌搜索了很多，但我沒有找到任何有用的東西。我認爲persistence.xml或pom.xml中缺少一些東西，但我無法弄清楚。 The whole exception is here.
Here is the file hierarchy of my project. (I cannot share image on SO yet)
，因爲我有一個從數據庫表生成〜30個單位我沒開實體包。
這裏是我的pom.xml：

正如在例外中提到的那樣，您需要在persistence.xml文件的中提供一個元素，並在應用程序服務器中配置數據源的名稱。您可以參考Java EE教程https://docs.oracle.com/javaee/7/tutorial/persistence-intro003.htm –

或者，您可以將事務類型切換爲RESOURCE_LOCAL，並在持久性內提供到數據庫的連接.xml已經在您的文件中實現。 – 2015-04-01 09:55:03
目前我沒有足夠的時間來開發此應用程序。只要我可以繼續，我會發佈一個aswer。謝謝彼得羅斯！ – LordScone 2015-04-02 18:57:03
