由于开发的时候用到了，所以也整理了一下，具体代码如下：

/**
         * @Title: httpGetRequest
         * @Description: httpGet请求
         * @param url
         * @return
         * @throws ParseException
         * @throws IOException
         */
        public static String httpGetRequest(String url) throws ParseException,
                IOException
        {
            CloseableHttpClient client = HttpClients.createDefault();
            HttpGet httpGet = new HttpGet(url);
            String retStr = "";
            HttpResponse response = client.execute(httpGet);
            retStr = EntityUtils.toString(response.getEntity(), "UTF-8");
            logger.info("报文接收时间:" + DateUtil.getCurrentDateTime());
            logger.info("接收内容:" + retStr);
            return retStr;
        }
    
        /**
         * @Title: httpGetRequest
         * @Description: post请求
         * @param url
         * @return
         * @throws ParseException
         * @throws IOException
         */
        public static String httpPostRequest(String url, String reqData)
                throws ParseException, IOException
        {
            CloseableHttpClient client = HttpClients.createDefault();
            HttpPost httpPost = new HttpPost(url);
            String retStr = "";
            StringEntity re = new StringEntity(reqData, "UTF-8");
            // httpPost.setHeader("Content-Type", "application/xml; charset=UTF-8");
            httpPost.setEntity(re);
            HttpResponse response = client.execute(httpPost);
            retStr = EntityUtils.toString(response.getEntity(), "UTF-8");
            return retStr;
        }

至此，该工具类结束，顺便说一下上面引入的jar文件，如下：

import org.apache.http.HttpResponse;  
import org.apache.http.ParseException;  
import org.apache.http.client.methods.HttpGet;  
import org.apache.http.client.methods.HttpPost;  
import org.apache.http.entity.StringEntity;  
import org.apache.http.impl.client.CloseableHttpClient;  
import org.apache.http.impl.client.HttpClients;  
import org.apache.http.util.EntityUtils;
