向java请求json参数，将json数组转换为java数组

import com.fasterxml.jackson.databind.ObjectMapper;

public class Main {
    public static void main(String[] args) {

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Content-Type", "application/json");
            
            // 读取返回的JSON参数
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder response = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                response.append(line);

            // 将JSON参数转换为Java数组
            ObjectMapper mapper = new ObjectMapper();
            String[] javaArray = mapper.readValue(response.toString(), String[].class);
            
            // 打印Java数组
            for (String element : javaArray) {

            }
        } catch (Exception e) {

        }
    }
