2. 代码

    public void sendGet(String url){


        CloseableHttpClient httpclient = HttpClients.createDefault();

        RequestConfig requestConfig = RequestConfig
                .custom()
                .setSocketTimeout(1000*60*60*5)
                .setConnectTimeout(1000*60*60*5)
                .build();

        HttpGet httpget = new HttpGet(url);
        httpget.setConfig(requestConfig);

        
        try {
            CloseableHttpResponse response = httpclient.execute(httpget);
            HttpEntity entity = response.getEntity();
            logger.info("response is {}" ,response);
            logger.info("entity is {}" ,entity);
            logger.info("result is {}" ,EntityUtils.toString(entity));
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            //response.close();
        }
    
    }

3.测试

    public static void main(String[] args) throws InterruptedException {
        Sample sample=new Sample();
        Calendar start=Calendar.getInstance();
        start.set(2017, 7, 23);
        
        Calendar end=Calendar.getInstance();
        end.set(2017, 7, 24);
        SimpleDateFormat formatter = new SimpleDateFormat ("yyyy-MM-dd"); 
        
        while(true){
            String startDate=formatter.format(start.getTime());        
            start.add(Calendar.DAY_OF_MONTH, 1);
            String endDate=formatter.format(start.getTime());    
            String url="http://test.test.com/daily/getDailyAction?startDate="+startDate
                    +"&endDate="+endDate;
            if(start.after(end)){
                break;
            }else{
                sample.sendGet(url);
                Thread.sleep(1000*60*2);    
            }            
        }

    }
