Java 测试因http客户端连接池问题而挂起

当我运行测试时，它们挂起在同一点上：当我尝试发送请求时。 我知道池中没有免费连接，但我不知道如何修复此问题。有什么想法吗？ 代码：

从日志：

首先，您必须关闭您的响应：

CloseableHttpResponse response = httpclient.execute(httpget);
try {
    <...>
} finally {
    response.close();
}

更新了代码。我正在检查响应代码。它只是一个URL。比如：

CloseableHttpResponse response = httpclient.execute(httpget);
try {
    <...>
} finally {
    response.close();
}

PoolingHttpClientConnectionManager cm = new 
PoolingHttpClientConnectionManager();
cm.setMaxTotal(200);
cm.setDefaultMaxPerRoute(20);
HttpHost localhost = new HttpHost("locahost", 80);
cm.setMaxPerRoute(new HttpRoute(localhost), 50);
CloseableHttpClient httpClient = HttpClients.custom()
    .setConnectionManager(cm)
    .build();
