Java TcpConnectionFactoryFactoryBean：同时使用SslContextSupport和SocketFactorySupport

我正在使用TCPConnectionFactoryBean（用于客户端、非NIO连接），并希望通过两种方式修改SSL套接字连接：

1/仅使用TLS1.2协议 我通过调用TcpConnectionFactoryFactoryBean.setSslContextSupport（）并提供一个带有TLSv1.2协议集的DefaultTcpSSLContextSupport对象来实现这一点

及

2/设置套接字连接超时 我通过调用TcpConnectionFactoryFactoryBean.setSocketFactorySupport（）并提供TcpSocketFactorySupport的自定义子类来实现这一点，该子类创建套接字，然后在连接调用中应用超时。这项技术已被记录在案

我有两个独立的工作，但不能让他们一起工作。查看TcpConnectionFactoryFactoryBean代码，很明显，获取SocketFactorySupport（）方法将只选择一个。因此，我认为我的做法是错误的。有人能提供一些指导吗

我想我已经将它合并到一个SocketFactorySupport类中，该类子类为DefaultTcpNetSSLSocketFactorySupport，然后与TcpConnectionFactoryFactoryBean.setSocketFactorySupport（）调用一起使用。我的子类如下所示，将DefaultTcpSSLContextSupport（带有协议集）和timeout传递给构造函数：

public class MySSLSocketFactorySupport extends DefaultTcpNetSSLSocketFactorySupport {

    private final int connectTimeout;

    public MySSLSocketFactorySupport(TcpSSLContextSupport sslContextSupport, int connectTimeout) {
        super(sslContextSupport);
        this.connectTimeout = connectTimeout;
    }

    @Override
    public ServerSocketFactory getServerSocketFactory() {
        throw new UnsupportedOperationException("This does not support server sockets");
    }

    @Override
    public SocketFactory getSocketFactory() {
        return new PostilionSocketFactory();
    }

    private class PostilionSocketFactory extends SocketFactory {

        private final SocketFactory delegate = MySSLSocketFactorySupport.super.getSocketFactory();

        @Override
        public Socket createSocket() throws IOException {
            return delegate.createSocket();
        }

        @Override
        public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
            Socket socket = this.delegate.createSocket();
            socket.connect(new InetSocketAddress(host, port), connectTimeout);
            return socket;
        }

        @Override
        public Socket createSocket(InetAddress host, int port) throws IOException {
            Socket socket = this.delegate.createSocket();
            socket.connect(new InetSocketAddress(host, port), connectTimeout);
            return socket;
        }

        @Override
        public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
            Socket socket = this.delegate.createSocket();
            socket.bind(new InetSocketAddress(localHost, localPort));
            socket.connect(new InetSocketAddress(host, port), connectTimeout);
            return socket;
        }

        @Override
        public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
            Socket socket = this.delegate.createSocket();
            socket.bind(new InetSocketAddress(localAddress, localPort));
            socket.connect(new InetSocketAddress(address, port), connectTimeout);
            return socket;
        }

    }

}

因此，您的解决方案是正确的。提供自定义的

TcpSocketFactorySupport

时，必须在该支持中提供

SslContext

。
