我已将代码版本从http更改为https,并且出于执行目的,我使用HttpClient client = HttpClientFactory.getHttpsClient()
。当我第一次尝试运行我的代码时,它运行良好,而下一次则抛出异常
java.lang.IllegalStateException:连接池关闭异常
我正在使用4.5HC。

如果您正在合并连接,请不要在请求后关闭客户端。
也就是说,您可能正在执行以下操作:
PoolingHttpClientConnectionManager pool = new PoolingHttpClientConnectionManager();
...
CloseableHttpClient httpclient = HttpClients.custom()
.setConnectionManager(pool)
.build();
try { // try-with-resources
HttpGet httpget = new HttpGet(url.toURI());
try (CloseableHttpResponse response = httpclient.execute(httpget);
InputStream fis = response.getEntity().getContent();
ReadableByteChannel channel = Channels.newChannel(fis)) {
// ... get data ...
} finally {
httpclient.close(); <====== !!
}
} catch (IOException | URISyntaxException e) {
// exception handling ...
}
httpclient.close()
导致您的下一个池连接失败。
