代码:
public static void main(String[] args) { String str = "{"bussDatas":[{"fieldDesc":"string","isSelected":0,"optionType":0,"optionValue":"string","orderNum":0,"placeHolder":"string"}],"moduleName":"string","packageId":"string","techDatas":{"fieldDesc":"string","isSelected":0,"optionType":0,"optionValue":"string","orderNum":0,"placeHolder":"string"}} "; JSONObject jsonObject = JSONObject.parseObject(str); // 格式化输出JSON String pretty = JSON.toJSONString(jsonObject, SerializerFeature.PrettyFormat, SerializerFeature.WriteMapNullValue, SerializerFeature.WriteDateUseDateFormat); System.out.println(String.format("原始JSON: %s", pretty)); // 获取JSON第一层所有的key Set<String> keys = jsonObject.keySet(); // 获取第一层每个key对应的值 的类型 for (String key : keys) { System.out.println(String.format("%s(key):%s(值类型)", key, jsonObject.get(key).getClass().getSimpleName())); } }
输出:
