使用PoolingHttpClientConnectionManager解决httpclient的多线程请求问题

public class TestMain {

    public static void main(String[] args) throws NSQException, TimeoutException {
        ExecutorService pool = Executors.newCachedThreadPool();
        // http请求
        PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
        cm.setDefaultMaxPerRoute(800);// 设置每个路由基础的连接
        cm.setMaxTotal(1000);//设置最大连接数//cm.setMaxPerRoute(new HttpRoute(httpHost), maxRoute);// 设置目标主机的最大连接数
        CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(cm).build();
        for (int i = 0; i <1000; i++) {
            TestRunnable tmp = new TestRunnable(httpClient);
            new Thread(tmp).start();
        }
        
    }
}

class TestRunnable implements Runnable {
    private final CloseableHttpClient httpclient;

    public TestRunnable(CloseableHttpClient httpClient) {
        this.httpclient = httpClient;
    }

    @Override
    public void run() {
        String id = "444";
        String name = "testName";
        Map param = new HashMap();
        param.put("id", id);
        param.put("name", name);

        String result = HttpClientUtil.doHttpPost("http://ip:port/testapi", param,httpclient);
        System.out.println(result);
    }
    
}
