            junit
            4.11
            test
        



        
            mysql
            mysql-connector-java
            8.0.21
        


        
            org.example
            mybatis
            1.0-SNAPSHOT
        


        
        
            org.apache.ibatis
            ibatis-core
            3.0
        

        
            org.mybatis
            mybatis
            3.4.5
        

    
        select * from mybatis.user

    

关于几个常见的错误点：

    org.apache.ibatis
    ibatis-core
    3.0

要不然ibatis包会查找不到

    
        src/main/java
        
            ***.xml
        
        false
    
    
        src/main/resources
        
            ***.xml
        
        false
    

public class MybatisUtils {

    private static SqlSessionFactory sqlSessionFactory;

    static {
        try {
            String resource = "mybatis.xml";
            Reader inputStream = Resources.getResourceAsReader(resource);
            sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    //获取SqlSession连接
    public static SqlSession getSession(){
        return sqlSessionFactory.openSession();
    }

}
