MyBatis优化技巧

☬配置日志文件

封装工具类

代码贴一下：

 package com.shxt.utils;

 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 MyBatisUtils(){};
     private static SqlSessionFactory sqlSessionFactory=null;
     private static final String PATH="config.xml";
     private static InputStream inputStream = null;
     static{
         try{
             inputStream=Resources.getResourceAsStream(PATH);
             sqlSessionFactory =new SqlSessionFactoryBuilder().build(inputStream);
         }catch(Exception e){
             System.out.println("加载MyBatis核心文件错误。异常信息为："+e.getMessage());
         }
     }
     public static SqlSession getSqlSession(){
         return sqlSessionFactory.openSession();
     }
     public static void closeSqlSession(SqlSession sqlSession){
         if(sqlSession!=null)sqlSession.close();
     }
 }
