mybatis连不上数据库
文件结构如下
实体类里没什么问题就上图片了
```java
public class MyBatisDemo {
public static void main(String[] args) throws IOException {
//1.加载MyBatis的核心配置文件,获 SqLSessionFactory
String resource = "mybatis-config.xml";
InputStream inputStream = Resources.getResourceAsStream(resource);
SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
//2.获取SqlSessionFactory对象
SqlSession sqlSession = sqlSessionFactory.openSession();
//3.执行sql
List<User> users = sqlSession.selectList("test.selectAll");
System.out.println(users);
sqlSession.close();
}
}
