项目以前使用的httpcore和httpclient 版本都比较低了，我将org.apache.httpcomponents下的httpcore（4.3.2）和httpclient（4.3.5）都换成新的版本（httpcore（4.4.4）和httpclient（4.5.2），结果导致发送http请求时报错.请问这个问题怎么解决呢？

public String postOrder(String xmlStr,String posturl) {
LOGGER.info("posturl:---------------"+posturl);
LOGGER.info("xmlStr:---------------"+xmlStr);
// posturl="https://api.mch.weixin.qq.com/pay/unifiedorder";

    HttpPost post = new HttpPost(posturl);
    try {
        String str = new String(xmlStr.getBytes(), "ISO8859-1");
        StringEntity entity = new StringEntity(str);
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
            String returnXml = EntityUtils.toString(response.getEntity(), "UTF-8");


            LOGGER.info("returnXml:---------------"+returnXml);
            return returnXml;
        }
    } catch (Exception e) {
        e.printStackTrace();
    } 
    return "";
}
