mybatisUtils工具類獲取SqlSession

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

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

public class mybatisUtils {
    private static SqlSessionFactory sqlSessionFactory;
    static{
        try {
            //使用Mybatis第一步：獲取sqlSessionFactory物件
            String resource = "mybatis-config.xml";
            InputStream inputStream = Resources.getResourceAsStream(resource);
            sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    //既然有了SqlSessionFactory，顧名思義，我們可以從中獲取SqlSession的例項
    //SqlSession完全包含了面向資料庫執行SQL命令所需的所有方法
    public static SqlSession getSqlSession(){
        return sqlSessionFactory.openSession();
    }
