旧com.alibaba.dubbo版本：2.5.9
新org.apache.dubbo版本：2.7.17

问题：旧的dubbo中设置过期时间放在字段default.timeout中，但是新的版本是在timeout中直接取值，会导致在旧的版本中设置的超时时间无效

这样的情况该如何兼容？

Assertions.assertEquals("bbb", urlParam1.getParameter("bbb"));
        URLParam urlParam2 = URLParam.parse(map);
        Assertions.assertEquals("ccc", urlParam2.getParameter("bbb"));

        Assertions.assertFalse(urlParam3.hasParameter("aaa"));
        Assertions.assertEquals(urlParam3, URLParam.parse(urlParam3.getRawParam()));
    }

    }
