在構(gòu)建 SqlSessionFactory的時(shí)候出了錯(cuò)誤

package?com.imooc.db;

import?java.io.IOException;
import?java.io.Reader;

import?org.apache.ibatis.io.Resources;
import?org.apache.ibatis.session.SqlSession;
import?org.apache.ibatis.session.SqlSessionFactory;
import?org.apache.ibatis.session.SqlSessionFactoryBuilder;

/*
?*?訪問(wèn)數(shù)據(jù)庫(kù)
?*/
public?class?DBAccess?{
???public?SqlSession?getSqlSession()?throws?IOException{
	????//通過(guò)配置文件獲取連接數(shù)據(jù)庫(kù)連接信息
	???Reader?reader=Resources.getResourceAsReader("com/imooc/config/Configuration.xml");
	???//通過(guò)配置信息來(lái)構(gòu)建一個(gè)SqlSessionFactory
	???System.out.println("輸出1");
	???SqlSessionFactory?sqlSessionFactory=???new?SqlSessionFactoryBuilder().build(reader);
	???System.out.println("輸出2");
	???//通過(guò)SqlSessionFactory打開一個(gè)會(huì)話
	?????SqlSession?sqlSession=sqlSessionFactory.openSession();
	?????return??sqlSession;
???}
}

下面是報(bào)的錯(cuò)誤
