Question

mybaits故障

这里的名字是叫mybatis-config.xml位于项目根目录下

<?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="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.cj.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/study"/>
                <property name="username" value="root"/>
                <property name="password" value="root"/>
            </dataSource>
        </environment>
    </environments>
    <mappers>
        <mapper url="file:TestMapper.xml"/>
    </mappers>
</configuration>

这里的名字是叫mybatis-config.xml也是位于项目根目录下

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="TestMapper">
    <select id="selectStudent" resultType="Mybaits_Test.entity.Student">
        select * from student
    </select>
</mapper>

名字叫做Student.java绝对路径位于D:\JavaWeb\src\Mybatis_Test\entity\Student.java

package Mybatis_Test.entity;

import lombok.Data;

@Data
public class Student {
    int Sid;
    String Sname;
    String Ssex;
}

名字是叫Main.java绝对路径位于D:\JavaWeb\src\Mybatis_Test\Main.java

package Mybatis_Test;


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

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.util.List;

public class Main {
    public static void main(String[] args) throws FileNotFoundException {
        //通过SqlSessionFactory得到一个SqlSessionFactory对象
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(new FileInputStream("mybatis-config.xml"));
        //获取一个SqlSessionFactory
        try(SqlSession session = sqlSessionFactory.openSession(true)){//自动提交
            List<Student> list = session.selectList("selectStudent");
            list.forEach(System.out::println);
        }
    }
}

数据库如下已连接

运行Main.java后报很多错

弄了半天还是没能解决问题，麻烦知情者帮忙解答！！谢谢
