我使用 Spring 3.0.6、GlassFish 3.1、EJB 3、JPA 2，我的提供者是 EclipseLink (JPA 2.0)
我的 webApplication 有这些配置文件：
持久性.xml：

我的控制器方法：
@Transactional
@RequestMapping(method = RequestMethod.POST)
public String onSubmit(@ModelAttribute("contract") Contract contract)
{
try
{
contractBean.creatCotract(contract);
} catch (Exception e)
{
e.printStackTrace();
}
return "someThing";
}
该项目显示数据，但不将数据保存在数据库中。我搜索了一周，但找不到任何答案。
