☬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();
    }
}
