求解Could not open Hibernate Session for transaction问题
我在使用SSH框架的时候，遇到一个这样的问题：
在一定的时间不对网站发送请求，一旦再访问就会出现：
Could not open Hibernate Session for transaction; nested exception is org.hibernate.TransactionException: JDBC begin transaction failed:
但是再刷新后就正常了，这个问题一直再困扰着我，后面我详细看了一下报错的问题，里面有一句：
java.net.SocketException: Software caused connection abort: socket write error
探究历程：我看了我的配置文件，事务的配置是正常的，不然的话刷新是不能够访问的，所以排除了这个问题。后来又怀疑是数据库的连接爆了，因为还有另外一个项目同时处于一个服务器中，调用同样端口的mysql 3306，但是那个项目就非常的正常。最后又怀疑是配置文件中：
<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>
这句话的问题，但是注释了以后还是出现问题，所以求救啊！
因此暂时我还是找不到解决方案，求大神帮助，谢谢！
完整的错误代码：
