Question

我想与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();

但这对需要客户端证书的网站不起作用。如果我不使用PoolingHttpClientConnectionManager（即按照以下方式对其进行评论）

//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？

Answer 1

使用配置了系统属性的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);

Answer 2

如果使用默认SSL上下文，则上述示例有效。如果您有自定义SSL上下文，例如：

    SslConfigurator sslConfig = SslConfigurator.newInstance()
    .trustStoreFile(...).trustStorePassword(...)
    .keyStoreFile(...).keyStorePassword(...).keyPassword(...);
SSLContext sslContext = sslConfig.createSSLContext();

然后将其提供给PoolingHttpClientConnectionManager：

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

不再需要调用ClientBuilder.sslContext（）。
