根本原因是

Error creating bean with name 'sessionFactory' defined in class path  
resource [applicationContext.xml]

所以看起来你的hibernate配置有问题。 stacktrace的最后一行显示NullPointerException。在eclipse或InteliJ中，您可以设置异常断点。为NullPointerException设置一个并调试启动。您可能会看到一些与您的问题无关的NullPointerExceptions，但最终您将看到正在终止启动的NullPointerExceptions。一旦找到它发生的位置，它很容易找到解决方案..
