错误：noClassDefFounderRorr：org/apache/commons/logging/logFactory

Question

我得到下一个错误：

import org.apache.http.HttpHost;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClientBuilder;

    String urlToSendRequest = Constants.HOST + Constants.URL;
    String targetDomain = Constants.DOMAIN;

    HttpClient httpClient = HttpClientBuilder.create().build();
    HttpHost targetHost = new HttpHost(targetDomain, 80, "http");

    HttpPost httpPost = new HttpPost(urlToSendRequest);

    httpPost.addHeader("SENDCODE", "UTF-8");
    //...

    StringEntity entity = new StringEntity(Constants.MSG, "UTF-8");
    entity.setContentType("application/xml");
    httpPost.setEntity(entity);

    HttpResponse response = httpClient.execute(httpPost);

我几乎可以肯定问题出在库导入上，但我不确定也不知道如何修复它。

请下载commons-logging jar文件并设置路径。
