Java -如何使用Gson解析json文件

<dependency>

public class JsonParserExample {
    public static void main(String[] args) {
        String filePath = "path/to/json/file.json";

        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            StringBuilder jsonContent = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                jsonContent.append(line);
            }

            // 使用JsonParser解析JSON字符串
            JsonParser parser = new JsonParser();
            JsonObject jsonObject = parser.parse(jsonContent.toString()).getAsJsonObject();

            // 使用Gson将JSON对象转换为Java对象
            Gson gson = new Gson();
            YourClass yourObject = gson.fromJson(jsonObject, YourClass.class);

            // 可以通过yourObject对象访问解析后的数据
            System.out.println(yourObject.getProperty1());
            System.out.println(yourObject.getProperty2());
            // ...

        } catch (IOException e) {
            e.printStackTrace();
        } catch (JsonSyntaxException e) {
            e.printStackTrace();
