2023-04-11 16:32:00

1：首先，设计好框架：

2：写工具类：

package com.ftz.Demo.utils;

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 MybatisUtil {

private static SqlSessionFactory sqlSessionFactory;

static {

try {

String resource = "mybatis-config.xml";

InputStream inputStream = Resources.getResourceAsStream（resource）;

sqlSessionFactory = new SqlSessionFactoryBuilder（）。build（inputStream）;

} catch （IOException e） {

e.printStackTrace（）;

}

public static SqlSession getSqlSession（）{

return sqlSessionFactory.openSession（）;

}

3：配置文件：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE configuration

PUBLIC "-//mybatis.org//DTD Config 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-config.dtd">

<property name="url"

value="jdbc:mysql://localhost:3306/mybatis?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8&useSSL=false"/>

</dataSource>

</environment>

</environments>

</mappers>

</configuration>
