json屬性過濾

各類json庫對屬性過濾都支持，但使用起來不夠靈活。本文介紹的方法經過讀取原生的 json字符串實現屬性動態過濾，因此不須要依賴具體的json庫。

例子以下：

String json = "{\"name\":\"mi米\",\"age\":30,\"weight\":100.1,\"Children\":[\"a\",\"b\",\"c\"],\"address\":{ \"city\":\"GuangZhou\",\"pro\":\"GuangDong\"}}";

        Assert.assertEquals("{\"name\":\"mi米\",\"weight\":100.1,\"address\":{ \"city\":\"GuangZhou\" }",
                JsonUtils.removeProperty(json, new String[]{"name", "weight", "address.city"}, true));

String json = "{\"name\":\"mi米\",\"age\":30,\"weight\":100.1,\"Children\":[\"a\",\"b\",\"c\"],\"address\":{ \"city\":\"GuangZhou\",\"pro\":\"GuangDong\"}}";

        Assert.assertEquals("{\"name\":\"mi米\",\"weight\":100.1,\"address\":{ \"city\":\"GuangZhou\" }",
                JsonUtils.removeProperty(json, new String[]{"age", "Children", "address.pro"}, false));
