// 转换为List对象 List<JSONObject> list = Arrays.asList(JSON.parseObject(jsonStr)); 通过上面的代码示例可以轻松地将Json字符串转换为List对象。需要注意的是,这里使用了阿里巴巴的fastjson库,如果需要进行转换则需要在项目中引入该库。 三、Jsonobject转List<Object> Jsonobject转List<Object>可以将Json转为List...

The default generalization uses the following C++ data types: std::string for strings, int64_t, uint64_t or double for numbers, std::map for objects, std::vector for arrays, and bool for Booleans. However, you can template the generalized class basic_json to your needs. Speed. There ...
