用Java代码简单模拟并发访问

思路主要是通过模拟多个线程同时发起http请求。

public class TestBingfa {
        //发送请求的url地址
  private final String url = "http://localhost:8085/bda-search";
  //模拟的并发量
  private static final int BINGFA = 199;
  
  private static CountDownLatch cdl = new CountDownLatch(BINGFA);
  
  public static void main(String[] args) {
    for (int i = 0; i < BINGFA; i++) {
      new Thread(new UserRequest()).start();
      cdl.countDown();
    }
  }
  
  public static class UserRequest implements Runnable{
    @Override
    public void run() {
      try {
        cdl.await();
      } catch (Exception e) {
        e.printStackTrace();
      }
          //使用工具类发送http请求
                String json2 = HttpClientUtil.sendHttpPostJson(url, getJson());
          System.out.println(new Date().getTime()+"::"+json2);
    }
    
  }
  
  //发送的请求参数
  public static String getJson(){
           return null;
  }
}
