该应用程序成功运行并打开“欢迎”#39;查看,但数据(GenericUser gu)不会持续......
答案 0 :(得分:1)
可能p:persistenceXmlLocation="classpath*:META-INF/persistence.xml"
这是错误的..
尝试将xml放在WEB-INF /文件夹中,并将其链接为:persistenceXmlLocation =“myxml.xml”
答案 1 :(得分:1)
您可以检查依赖关系罐是否在正确的位置可用吗?
答案 2 :(得分:0)
终于解决了......发布我的解决方案以供将来参考..
在到达工作解决方案之前我改变了很多东西..我不记得到底是什么问题..所以我提到了我所做的所有改变。
将所有xsd版本更改为3.1 ..(可能没有关系)
如果您使用tomcat,请使用spring-tomcat-weaver.jar
进行加载时间编织,如上所述here。
主要问题:
Spring文档说明了以下内容:
<tx:annotation-driven/>
仅在其定义的相同应用程序上下文中查找bean上的@Transactional。这意味着,如果您为DispatcherServlet放入WebApplicationContext,它只检查控制器中的@Transactional bean,而不是你的服务。有关更多信息,请参见第15.2节“DispatcherServlet”。
由于在<tx:annotation-driven>
中声明了applicationContext.xml
,因此必须在应用程序上下文中发现所有想要使用@Transactional
的类。因此,您还需要在应用程序上下文中指定<context:component-scan>
。但请确保您没有重新发现dispatcher-servlet.xml
中已指定的控制器。您可以使用include-filter
元素中的exclude-filter
和<context:component-scan>
元素来实现此目的。
详细解释here。
您将无法在控制器中使用@Transactional
..(您不应该使用IMO)
