I have started using Hibernate 4.3.8 and was trying out a basic program to insert and retrieve a user. Below are my files.
我已经开始使用 Hibernate 4.3.8 并且正在尝试一个基本的程序来插入和检索用户。下面是我的文件。

I have tried different ways of initializing the SessionFactory, but nothing seems to work. I am using Hibernate 4.3.8-Final
我尝试了不同的初始化 SessionFactory 的方法，但似乎没有任何效果。我正在使用 Hibernate 4.3.8-Final
Thanks in advance

Disable the second level cache in hibernate.cfg.xml.
在 hibernate.cfg.xml 中禁用二级缓存。
Include the below line of code to disable the second level cache .
包括以下代码行以禁用二级缓存。
<!-- Disable the second-level cache -->
<property
name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

Get rid of three configs related to cache...you should be good
摆脱三个与缓存相关的配置......你应该很好
