MyBatis学习中遇到的一个离谱错误

当junit5测式类类名以Test开头时

        

public class Testadsdasd {


    private SqlSession sqlSession;

    @BeforeEach
    public void init() throws IOException {
        sqlSession = new SqlSessionFactoryBuilder()
                .build(Resources.getResourceAsStream("mybatis-config.xml"))
                .openSession();

    }

    @Test
    public void testQueryOrderById() throws IOException {
        OrderMapper mapper = sqlSession.getMapper(OrderMapper.class);
        Order order = mapper.queryOrderById(1);
        System.out.println("order = " + order);

    }

    @AfterEach
    public void closeAll(){

        sqlSession.commit();
        sqlSession.close();
    }
}

在使用了AfterEach或BeforEach注解后，@Test中无法使用sqlSession报错

There are test failures.

Please refer to G:\IdeaProjects\test444maybaits\som\target\surefire-reports for the individual test results.

查找xml中的报错信息后

        说是sqlSession为空

修改类名字后

public class asdasdasdsa {


    private SqlSession sqlSession;

    @BeforeEach
    public void init() throws IOException {
        sqlSession = new SqlSessionFactoryBuilder()
                .build(Resources.getResourceAsStream("mybatis-config.xml"))
                .openSession();

    }

    @Test
    public void testQueryOrderById() throws IOException {
        OrderMapper mapper = sqlSession.getMapper(OrderMapper.class);
        Order order = mapper.queryOrderById(1);
        System.out.println("order = " + order);

    }

    @AfterEach
    public void closeAll(){

        sqlSession.commit();
        sqlSession.close();
    }
}

正常运行

order = Order(orderId=1, orderName=o1, customerId=1, customer=Customer(customerId=1, customerName=c01, orders=null))

更离谱的是

把sqlSession的使用放到AfterEach之后

@AfterEach
public void closeAll(){
    OrderMapper mapper = sqlSession.getMapper(OrderMapper.class);
    Order order = mapper.queryOrderById(1);
    System.out.println("order = " + order);
    sqlSession.commit();
    sqlSession.close();
}

又正常了 没事了：）

总结

        不知道原因，有大佬知道的话，求解答

        但是知道了junit5.3.1测试类类名不能以Test开头，如果以Test开头，@Test下的内容会被单独隔开，不能使用@BeforeEach写好的东西
