我的Web应用程序使用Tomcat 6.0.18和Spring 3.0.5以及eclipselink 2.0.1和javax.persistence 2.0.0,SQL Server数据库.我无法弄清楚配置,也无法找到具有此类配置的工作示例.我尝试将loadTimeWeaver的属性添加到entityManagerFacotory中,但它在Spring 3中破坏了AutoWired批注,如下面的applicationContext.xml中所示:

<context:load-time-weaver/>

在appname-servlet.xml中:

但是当我禁用LoadTimeWeaver时,我的应用程序可以从JPA代码创建数据库,但无法将数据保存到数据库中.
