The code ``` static class TestParams{ Params params; static class Params{ private String domain; private String showDay; private Map<String,Integer> date; } // setter and getter ``` TestClass ``` String testJson = "[{\"params\":{\"date\":{\"intervalDay\":0},\"domain\":\"weather\",\"showDay\":\"今天\"}}]"; List<TestParams> testList = GsonUtils.getInstance().fromList(testJson,TestParams.class); assertEquals(testList.get(0).getParams().getDate().get("intervalDay"),0); ``` I think the issue may be related to `gson` configuration. -- This is an automated message from the Apache Git Service.
