快要疯了。 Spring 3.0.x Hibernate 3.6.5 JPA - 无法配置EntityManagerFactory

标签： hibernate spring gwt jpa

过去几个小时我一直在发疯。我根本无法使用JPA配置Spring，Hibernate。

我有一个默认的GWT项目。唯一非默认的事情是我决定使用JSON与服务器进行双向通信。我正在使用jax-rs（jersey）来做到这一点。

我的war目录在尝试将spring或hibernate添加到项目之前看起来像这样：

  • 战
  • 战/项目名称
  • 战/ WEB-INF
  • war / WEB-INF / classes（和子目录）
  • 战/ lib中
  • 战/ LIB / ASM-3.1.jar
  • 战/ LIB / flexjson-2.1.jar
  • 战/ LIB / GWT-的servlet.jar
  • 战/ LIB /杰克逊核-ASL-1.7.1.jar
  • 战/ LIB /杰克逊 - JAXRS-1.7.1.jar
  • 战/ LIB /杰克逊映射器-ASL-1.7.1.jar
  • 战/ LIB /杰克逊-XC-1.7.1.jar
  • 战/ LIB / Jersey的客户端 - 1.7.jar
  • 战/ LIB /球衣核-1.7.jar
  • 战/ LIB / Jersey的JSON-1.7.jar
  • 战/ LIB /球衣 - 服务器 - 1.7.jar
  • 战/ LIB /抛放-1.1.jar
  • 战/ LIB / JSR311-API-1.1.1.jar
  • 战/ web.xml中

还不错，13个JARS和一个包含几行的XML文件。它非常紧凑，我让JSON按预期来回传递。完善。现在我所要做的就是添加ORM。我在过去的项目中使用过Spring和hibernate，但我从来没有真正配置它们。

问题是，您如何找到如何配置它们？如果你谷歌它，你会发现数以百万计的教程（其中大部分是过时的）。 hibernate教程很棒，我几乎100％肯定我可以轻松地进行简单的休眠（事实上我很久以前做过）。但我想坚持使用行业惯例，并将Hibernate与Spring和JPA一起使用。

我在这里找到了这个教程，它似乎是最新的： http://www.javacodegeeks.com/2010/05/gwt-2-spring-3-jpa-2-hibernate-35.html

但我要进入圈子。问题后的问题。在我启动GWT应用程序后，我得到了这个：

  1. 有谁知道为什么我遇到上述错误？
  2. 有人可以向我推荐一个关于如何配置这些框架的非常简单的（及时更新！）教程吗？这不是我不理解hibernate。我在过去3年里一直使用它（虽然在过去的几个月中只是以Grails的形式出现了很多）。

    3. 由于

4 个答案:

答案 0 :(得分：3)

应用程序似乎正在寻找validation provider。将hibernate-validator 4.x添加到类路径中。

答案 1 :(得分：1)

您使用的是哪个版本的GWt？ GWT2.3及更高版本具有验证器实现。您需要在类路径中进行详细添加。

答案 2 :(得分：1)

我收到了同样的错误消息：

  

org.springframework.beans.factory.BeanCreationException：创建名为'myName'的bean时出错......：   调用init方法失败;嵌套异常是javax.persistence.PersistenceException：   [PersistenceUnit：MyPersistenceUnit]无法配置EntityManagerFactory“

原来，其中一个新添加的Entity类没有定义主键@Id。希望将来帮助某人。

答案 3 :(得分：0)

“如果您不想使用hibernate bean验证，可以添加它 行到你的休眠persistence.xml文件：

  <validation-mode>NONE</validation-mode>"

这样可以在不添加类路径的情况下解决问题。
