java - 通过属性文件传递服务器 URL 在 apache http 客户端中不起作用

Question

我正在尝试通过属性文件读取 url 并传递到 apache http post 构造函数。当我这样做时，我收到 404 错误，当对其进行硬编码时，它工作正常。我不知道是什么两种方法之间的差异。从属性文件读取后，我在控制台上打印变量，它显示了确切的 url，但是当我在 http apache 客户端中传递相同的字符串变量时，我收到“404 未找到”。任何人都可以指导我吗？谢谢

    requestURL = MWTConfiguration.getInstance().getValue("NPCI_AUTH_URL");
                System.out.println("Request URL :"+requestURL);
                objAuthRequest.setPid(objFITransXTRequest.getPid());
                objAuthRequest.setRbd(""); 
 authResponse =objMWTHttpClient.execute(strRequestJson, requestURL);  

客户端代码:

public String execute(String requestData, String strURL) throws ParseException, Exception {
        String strResponse = "";
        StringBuffer objSBuffer = new StringBuffer();
        try {
            HttpClient httpClient = HttpClientBuilder.create().build();
            System.out.println("URLLLL : :"+strURL);
            HttpPost reqFundTransf = new HttpPost(strURL);
            StringEntity params = new StringEntity(requestData);
            reqFundTransf.addHeader("content-type", "application/json");
            reqFundTransf.setEntity(params);
            HttpResponse objResponse = httpClient.execute(reqFundTransf);
            HttpEntity objRespEntity = objResponse.getEntity();
            BufferedReader objBReader = new BufferedReader(new InputStreamReader(objRespEntity.getContent()));

            while ((strResponse = objBReader.readLine()) != null) {
                objSBuffer.append(strResponse);
            }

        } catch (Exception e) {
            throw new Exception(e);
        }
        return objSBuffer.toString();

使用修剪功能，字符串末尾或开头可能有空格。

HttpPost reqFundTransf = new HttpPost(strURL.trim());
