myBatis学习——SqlSession对象获取的封装工具类

myBatis 中需要 SqlSession对象中的方法来调用接口中的方法或通过反射取得接口对象，将SqlSession对象的获取封装，便于以后的使用

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;public class SqlSessionFactoryUtil {//mybatis的主配置文件路径private static String path="config/mybatis-config.xml";private static Reader read;private static SqlSessionFactory  factory=null;static {try { read= Resources.getResourceAsReader(path);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}/* * 通过SqlSessionFactoryBuilder对象的build方法获得单例SqlSessionFactory工厂对象*/private static SqlSessionFactory getFactory(){if(factory==null){SqlSessionFactoryBuilder builder = new SqlSessionFactoryBuilder();factory= builder.build(read);}return factory;}//通过SqlSessionFactory工厂对象取得SqlSession对象public static SqlSession  getSession(){SqlSession s=getFactory().openSession(true);return s;}}
