Java 弹簧、支柱和x2B；休眠项目启动

我有下一个配置：

hibernate.cfg.xml 我查过类似的问题，但没有发现

更新

我已从应用程序上下文中删除上下文扫描，现在获取NPE地址：

java.lang.NullPointerException com.project.controller.ListProductAction.execute（ListProductAction.java:25）

以下是代码：

public String execute() {
    listProduct = productDao.list();
    return SUCCESS;
  }

正如我所研究的，sessionFactory是正常实例化的，但spring（据我所知）无法进行绑定，因此productDao在ListProductAction处为空

更新

这是警告吗？你能忽略它吗？问题是什么？不，这不是警告。这是我在服务器控制台中看到的，我无法访问应用程序的起始页（tomcat没有运行它，尽管它应该根据设置运行）。还有一个非常大的stacktrace，但是我在这里只添加了根cause@IsaiahvanderElst这是一个无用的，个人的，也是误导性的评论，因为这是Struts2，不是Struts，它们完全是different@IsaiahvanderElstJ2EE绝对是传统的，因为J2EE是Java1.4。从Java1.5开始，它被称为JavaEE。我使用JavaEE和Struts2，没有任何问题。根据我上一次看到的内容（几年前），SpringMVC在美国非常流行，而在世界其他地方却不那么流行。（继续->）我有时使用它，我喜欢它，它有一些比Struts2更多和更少的东西，我仍然更喜欢。JavaEE标准MVC框架是JSF2，我不太喜欢它。请注意，Struts2即将发布，因为2015年的Struts2与2008年的Struts2有很大不同。Struts3将是2015年的Struts2，还有更多。。。然而，我想所有这些技术很快就会被客户端framworks所取代。
