mybatis insert 数据库没数据

package com.travel.utils;

import java.io.IOException;
import java.io.InputStream;

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

public class MybatisUtils {
	
	private static SqlSessionFactory sqlSessionFactory = null;
    
	public static SqlSessionFactory createFactory() throws IOException {
	    if(null == sqlSessionFactory){
	//            加载配置文件
	        InputStream is = Resources.getResourceAsStream("resource/mybatis.xml");
	    
	        SqlSessionFactoryBuilder builder = new SqlSessionFactoryBuilder();
	        sqlSessionFactory = builder.build(is);
	        is.close();
	    }
	    return sqlSessionFactory;
	}
	
	public static SqlSession getSession() throws IOException {
        return createFactory().openSession(true);
    }



    
}

其中createFactory().openSession(true) 这个true解决问题。
