apache-httpclient-4.x - 如何将 SSL 与 Jersey 2.x 和 Apache 连接管理器一起使用

Question

我想对我的 Jersey 2.x 休息客户端使用连接池。我有以下代码:

ClientConfig clientConfig = new ClientConfig();
PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager();
connectionManager.setMaxTotal(100);
connectionManager.setDefaultMaxPerRoute(20);
clientConfig.property(ApacheClientProperties.CONNECTION_MANAGER, connectionManager);

clientConfig.connectorProvider(new ApacheConnectorProvider());  

Client client = ClientBuilder.newBuilder()
    .withConfig(clientConfig)
    .sslContext(SslConfigurator.getDefaultContext())
    .build();

但这不适用于需要客户端证书的站点。如果我不使用 PoolingHttpClientConnectionManager(即像这样注释掉它:)

//clientConfig.property(ApacheClientProperties.CONNECTION_MANAGER, connectionManager);

然后发送客户端证书。

如何设置 PoolingHttpClientConnectionManager 以使用 javax.net.ssl... 属性？

使用配置有系统属性的 SSL 套接字工厂

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", PlainConnectionSocketFactory.getSocketFactory())
        .register("https", SSLConnectionSocketFactory.getSystemSocketFactory())
        .build();
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(socketFactoryRegistry);
