java对象或者list接受json(字符串)，用jsonObject不容易报错；还有一种使用google封装的Gson

@Slf4j
@RunWith(SpringRunner.class)
@SpringBootTest(classes = CollectApplication.class)
public class JsonTest {
    @Test
    public void test() {
        /**
         * [{\"key\":1, \"keyValue\":\"自定义公式\",\"dataKey\":\"complete_design\",\"dataText\":\"建筑面积\",
         * \"operationType\":\"4\",\"value\":\"95\",\"isNumber\":\"2\",\"isChooseBool\":\"true\"},
         * {\"key\":2,\"keyValue\":\"具体金额\"}]
         */
        String dataValue = "[{\"key\":1, \"keyValue\":\"自定义公式\",\"dataKey\":\"complete_design\","
                + "\"dataText\":\"建筑面积\",\"operationType\":\"4\",\"value\":\"95\",\"isNumber\":\"2\","
                + "\"isChooseBool\":\"false\"},{\"key\":2,\"keyValue\":\"具体金额\",\"isChooseBool\":\"true\"}]";
        List<JSONObject> jsonObjects = JSON.parseArray(dataValue, JSONObject.class);
        for (JSONObject jsonObject : jsonObjects) {
            int key = jsonObject.getIntValue("key");
            System.out.println("========" + key);
            if (Objects.equals(ShopTemplateDataConstant.FIRST_KEY, key)) {

            }
        }
    }
}

还有一种使用google封装的Gson

Gson gson = new Gson();
HashMap map = gson.fromJson(accessTokenTnfo, HashMap.class);
String key = (String)map.get("key");
