不知道是不是jar包有没有问题

解决方案

说实话，我每次看到大段的异常信息都会莫名的抵触，但是开发久了，就会发现异常信息真的是编程人员忠实的伙伴，它严谨、无情地指出你所有的错误。哪怕是标点、输入法错误的圆角，空格，都是错误根源。
所以，我想补充的是，学会跟异常信息相处吧，如果你能耐心看到最后面的异常根源就会发现错误根源了。get/set方法缺失，检查是否缺失，拼写等。

解决方案二：

Account类的userName字段没有get方法，看下面提示
Caused by: org.hibernate.PropertyNotFoundException: Could not find a getter for userName in class com.guigu.ssh.hibernate.entities.Account
