解析Java中JSON文件的字段

Question

我有一个以下格式的 JSON 文件，并且想解析数据以插入表中。 我坚持如何从文件中提取数据。 数据如下所示：

{"business_id": "vcNAWiLM4dR7D2nwwJ7nCA", "full_address": "4840 E Indian School Rd\nSte 101\nPhoenix, AZ 85018", "hours": {"Tuesday": {"close": "17:00", "open": "08:00"}, "Friday": {"close": "17:00", "open": "08:00"}, "Monday": {"close": "17:00", "open": "08:00"}, "Wednesday": {"close": "17:00", "open": "08:00"}, "Thursday": {"close": "17:00", "open": "08:00"}}, "open": true, "categories": ["Doctors", "Health & Medical"], "city": "Phoenix", "review_count": 7, "name": "Eric Goldberg, MD", "neighborhoods": [], "longitude": -111.98375799999999, "state": "AZ", "stars": 3.5, "latitude": 33.499313000000001, "attributes": {"By Appointment Only": true}, "type": "business"}

到目前为止我有这个代码：

fReader = new FileReader(filePath);
bufferedReader = new BufferedReader(fileReader);
String line;
bufferedReader.readLine();
int index = 0;
while ((line = bufferedReader.readLine()) != null) {
     String businessInfo[] = line.split("\t");
                
     //add a new object based on my OOP design

Answer 1

为什么不使用 JSON 解析器，如 Gson 或 Jackson 等？ 将有效负载传递给它，它将返回 Object 您将转换为您的类型。
