Spring 3休眠JPA 2.0 Maven和值'2.0'錯誤

Question

我試圖從頭創建應用程序。在新的Maven項目中，我添加了很多依賴項，創建persistence.xml，application.xml並修改web.xml。還介紹一些實體和控制器。接下來我嘗試使用MVN碼頭上碼頭運行：跑，然後我得到這個異常：

org.xml.sax.SAXParseException: cvc-complex-type.3.1: Value '2.0' of attribute 'version' of element 'persistence' is not valid with respect to the corresponding attribute use. Attribute 'version' has a fixed value of '1.0'. 

谷歌上搜索我learnd，這可能是因爲我在類路徑中的幾個實現JPA後，和一個他們可能是1.0。但我無法理解，它可能是因爲我只使用最新版本的hibernate entiry manager，並且顯式不添加任何其他實現。哪裏可能有bug？問題可能是因爲我添加了許多彈簧依賴關係？

Answer 1

恕我直言，你的POM，它的依賴和persistence.xml文件看起來不錯。我看不出任何JPA 1.0優先於JPA 2.0的原因，至少在你的應用程序方面。因此，您應該檢查另一端，即您將應用程序部署到的Jetty實例。確保它的庫（提供給應用程序類路徑的庫）不包含JPA 1.0（它的實現與舊的Hibernate版本一樣），因爲那時JPA 1.0有優先權。我真的沒有看到任何其他原因，但在classpath中實現了舊的JPA實現。

或者，只需嘗試下載vanilla Tomcat，解壓縮並部署應用程序（WAR文件）。這將確保您的應用程序正常，這是一個容器的問題。
