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

試過目前幾乎所有看到的代碼。仍然報錯，都指向SessionFactory創建的這行。。

官方那個給的

package?test;

import?java.io.IOException;

import?org.hibernate.Session;

import?org.hibernate.cfg.Configuration;
import?org.hibernate.service.ServiceRegistry;
import?org.junit.Test;
import?bean.Message;

public?class?MessageTest?{
????private?SessionFactory?sessionfactory;
????private?org.hibernate.Session?session;

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