	public?static?SqlSession?getSession()?throws?IOException{
		//通過配置文件獲取數(shù)據(jù)庫鏈接相關信息(配置文件放在src下)
		reader=Resources.getResourceAsReader("Configuration.xml");
		//通過配置信息構建SqlSessionFactory
		sessionFactory=new?SqlSessionFactoryBuilder().build(reader);
		//打開會話SqlSession
		session=sessionFactory.openSession();
		return?session;
	}
	private?DBAccess(){}
}

測試獲取鏈接類

package?icoc.jmteam.TestOfMybatis.dao;

import?java.io.IOException;

import?org.apache.ibatis.session.SqlSession;

public?class?MybatisTest?{
	SqlSession?session;
	public?void?TestToConnect(){
		try?{
			
			session=DBAccess.getSession();
			if(session!=null){
				System.out.println("創(chuàng)建會話成功");
			}else{
				System.out.println("創(chuàng)建會話失敗");
			}
		}?catch?(IOException?e)?{
			System.out.println("異常,創(chuàng)建會話失敗");
		}finally{
			session.close();
			System.out.println("會話已關閉");
		}
		
		
	}
	
	
	public?static?void?main(String?args[]){
		new?MybatisTest().TestToConnect();
	}
	
}
