究竟該如何創(chuàng)建SessionFactory？（hibernate5.0.x以上版本）

試過(guò)目前幾乎所有看到的代碼。仍然報(bào)錯(cuò)，都指向SessionFactory創(chuàng)建的這行。。

可以運(yùn)行的，但是注意hibernate 和jdk的版本的匹配（我的就出了major.minor version 52.0問(wèn)題?，F(xiàn)在用hibernate 5.1.2匹配jdk7 使用），/HibernatePra/src/hibernate.cfg.xml，確認(rèn)hibernate.cfg.xml的放置位置（我的放在了默認(rèn)，其它位置的方式還未嘗試）。
