如何搭建MyBatis使用环境

1引入mybatis和数据库驱动的jar
mybatis-3.2.8.jar和mysql-connector-java-5.1.10-bin.jar

2引入SqlConfigMap.xml
3获取SqlSession

SqlConfigMap.xml可以如下配置

<?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">
<configuration>
    <environments default="environment">
    
        <environment id="environment">
            <transactionManager type="JDBC"> </transactionManager>
                <dataSource type="POOLED">
                    <property name="driver" value="com.mysql.jdbc.Driver"/>
                    <property name="url" value="jdbc:mysql://localhost:3306/student"/>
                    <property name="username" value="root"/>
                    <property name="password" value="g"/>
                </dataSource>
        </environment>
        
    </environments>
</configuration>

SqlSessionUtil

package util;

import java.io.InputStream;

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

public class SqlSessionUtil {
    public static SqlSession getSession(){
        SqlSessionFactoryBuilder factoryBuilder=new SqlSessionFactoryBuilder();
        InputStream config=SqlSessionUtil.class.getClassLoader().getResourceAsStream("SqlMapConfig.xml");
        SqlSessionFactory sf= factoryBuilder.build(config);
        SqlSession session=sf.openSession();
        return session;
    }
}
