下面是一个通过Http远程调用的例子，亲测有效，无需其它客户端包。

import org.apache.commons.io.IOUtils;
import org.apache.http.HttpEntity;
import org.apache.http.client.methods.CloseableHttpResponse;
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;

String url = "http://192.168.190.1:8080/test/query";

String data = "{\"bool\": \"0001,0002\","
           +"\"timeEnd\": \"20180505000000\","
           +"\"timeStart\": \"20180504200000\","
           +"\"wtgid\": \"BWAA,BWAE\","
           +"\"preHandle\": [{\"boolId\": \"0001\","
           +"\"filter\": \"24890-24893\","
           +"\"id\": \"1\","
           +"\"interval\": \"\","
           +"\"isZero\": \"\" }]}";

/*
       * 过时了 DefaultHttpClient client = new DefaultHttpClient( new
       * PoolingClientConnectionManager());
       */
       CloseableHttpClient client = HttpClients.createDefault();
       HttpPost httpPost = new HttpPost(url);
       httpPost.setHeader("Content-Type", "application/json;charset=UTF-8");
       StringEntity se;
       String result = "";
       try {
           se = new StringEntity(data);
           se.setContentType("text/json");
           httpPost.setEntity(se);
           CloseableHttpResponse response2 = null;
           response2 = client.execute(httpPost);
           HttpEntity entity2 = null;
           entity2 = response2.getEntity();
           result = EntityUtils.toString(entity2, "UTF-8");
       } catch (Exception e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
