类型不匹配:无法从 org.json.JSONObject 转换为 org.json.simple.JSONObject

Type mismatch: cannot convert from org.json.JSONObject to org.json.simple.JSONObject

执行以下代码时出现类型不匹配错误。请帮我解决一下。

/**
 * Gets the versionID for the project. 
 * 
 * @param versionName
 * @param projectId
 * @throws IOException
 * @return the ID for the specified Version in the specified Project
 */
public static String getVersionID(final String versionName, final String projectId)
        throws IOException {
    // Get list of versions on the specified project
    final JSONObject projectJsonObj =
            httpGetJSONObject(ZAPI_URL + "util/versionBoard-list?projectId=" + projectId);
    if (null == projectJsonObj) {
        throw new IllegalStateException("JSONObject is null for projectId=" + projectId);
    }

    final JSONArray versionOptions = (JSONArray) projectJsonObj.get("versionOptions");

    // Iterate over versions
    for (int i = 0; i < versionOptions.length(); i++) {
        final JSONObject obj2 = versionOptions.getJSONObject(i);
        // If label matches specified version name
        if (obj2.getString("label").equals(versionName)) {
            // Return the ID for this version
            return obj2.get("value");
           // return obj2.getString("value");
        }
    }

    throw new IllegalStateException("Version ID not found for versionName=" + versionName);
}

错误在以下行:

final JSONObject obj2 = versionOptions.getJSONObject(i);

然后是 if 部分和 return 部分。

确保您导入的是 org.json.JSONObject,而不是 org.json.simple.JSONObject。该错误表明您的代码正在尝试转换为后者,但收到的是前者。因为两个类本地名称相同,很容易不小心导入错
