spring + hibernate entityManagerFactory / configurations / context .xml

标签： java spring hibernate spring-mvc

我找不到使用spring + hibernate工作context.xml的方法。我无法创建entityManagerFactory的{​​{1}}实例并且无法在entityManagerFactory上的context.xml声明中找到错误。

我收到此错误：

org.springframework.beans.factory.BeanCreationException: 
Error creating bean with name 'entityManagerFactory' defined in PortletContext resource 
[/WEB-INF/spring/portlet-context.xml]: Invocation of init method failed;
nested exception is java.lang.IncompatibleClassChangeError: Implementing class

下面是我的pom.xml

错误说 - java.lang.IncompatibleClassChangeError：实施课程

这意味着在某些点，interface已更改为abstract class（或反之亦然），但实施者原始界面 不已修改并重新编译以适应此（不兼容）更改。

答案 1 :(得分：0)

生活中的问题就是问题。不知道liferay有什么问题，但我删除了所有内容，并安装了新的liferay 6.2 ce，安装完成后重新启动我部署war文件并没有问题。

感谢您对此的帮助...
