这是我的 application-dev.yml 中配置的多数据源，其他按照pdf中配置完成以后
执行测试代码时提示：

我确定我的连接url 和 username password以及driver都是正常的，因为在我单独只连接kylin一个数据源执行操作时，是能够查询出结果的；
这是我的测试代码：
@Test
public void test() {
Long id = 1L;
DynamicDataSource.clearDataSource();
DynamicDataSource.setDataSource("second");
List<Map> map = zxCalculatorDao.kylinTest();
｝
默认数据源是mysql，执行前先改变了一下数据源，再执行的，辛苦哪位大神给解答一下
