如何将 `org.codehaus.jettison.json.JSONObject` 转换为 `org.json.JSONObject`
import org.codehaus.jettison.json.JSONObject;
....
....
JSONObject rawSchema = ExportUtil.getFileAndConvertToJson(environment.getProperty("export.path")+ "schema.json");
org.json.JSONObject rawSchema1 = rawSchema; // 异常：类型不匹配：无法从org.codehaus.jettison.json.JSONObject转换为org.json.JSONObject
------
public static JSONObject getFileAndConvertToJson(String filePath) {
File fileToDownload = new File(filePath);
JSONObject jsonObject = null;
try (InputStream inputStream = new FileInputStream(fileToDownload)) {
BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
StringBuilder responseStrBuilder = new StringBuilder();
String inputStr;
while ((inputStr = streamReader.readLine()) != null)
responseStrBuilder.append(inputStr);
jsonObject = new JSONObject(responseStrBuilder.toString());
} catch (Exception e) {
e.printStackTrace();
}
return jsonObject;
}

异常已经表明了一切，ExportUtil.getFileAndConvertToJson 正在返回一个 org.codehaus.jettison.json.JSONObject，而您试图将其赋值给一个 org.json.JSONObject 变量。
英文:
The exception says it all, ExportUtil.getFileAndConvertToJson is returning a org.codehaus.jettison.json.JSONObject which you are trying to assign to a org.json.JSONObject variable

你应该使用相同的类JSONObject，而不是org.json.JSONObject。
英文:
you should use the same class JSONObject, not org.json.JSONObject.
