Java WebSocket客户端在连接时关闭

我正在尝试用Java构建一个独立的WebSocket客户端，它连接到C#中的WebSocket服务器。我正在使用为WebSocket服务器生成的自签名证书。我能够使用WSS连接到Chrome浏览器中的WebSocket服务器，没有任何问题。当尝试使用该库时，它不起作用。OnClose方法在连接时立即被调用

我在生成的*.pfx文件中有一个自签名证书，该文件用于C#服务器，并导入到我的受信任根存储中。我使用keytool从这个文件创建了一个*.jks（我认为我做得很正确）。我在代码中使用keystore.jks，它是由keytool生成的

以下是我的主要方法：

public static void main(String[] args) throws Exception {
    ChatClient chatclient = new ChatClient("wss://thomas.localnetwork.com:65120/wsserver?userId=Thomas", "Thomas", "1", "1", "L");
    // load up the key store
    String STORETYPE = "JKS";
    String KEYSTORE = "C:\\Users\\thomas\\Desktop\\keystore.jks";
    String STOREPASSWORD = "test12345";
    String KEYPASSWORD = "test";

    KeyStore ks = KeyStore.getInstance( STORETYPE );
    File kf = new File( KEYSTORE );
    ks.load( new FileInputStream( kf ), STOREPASSWORD.toCharArray() );

    KeyManagerFactory kmf = KeyManagerFactory.getInstance( "SunX509" );
    kmf.init( ks, KEYPASSWORD.toCharArray() );
    TrustManagerFactory tmf = TrustManagerFactory.getInstance( "SunX509" );
    tmf.init( ks );

    SSLContext sslContext = null;
    sslContext = SSLContext.getInstance( "TLS" );
    sslContext.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null );
    // sslContext.init( null, null, null ); // will use java's default key and trust store which is sufficient unless you deal with self-signed certificates

    SSLSocketFactory factory = sslContext.getSocketFactory();// (SSLSocketFactory) SSLSocketFactory.getDefault();

    chatclient.setSocketFactory( factory );

    chatclient.connectBlocking();

    BufferedReader reader = new BufferedReader( new InputStreamReader( System.in ) );
    while ( true ) {
        String line = reader.readLine();
        if( line.equals( "close" ) ) {
            chatclient.closeBlocking();
        } else if ( line.equals( "open" ) ) {
            chatclient.reconnect();
        } else {
            ucm.send( line );
        }
    }
}

以下是我收到的例外情况：

有没有办法让我了解更多关于握手的细节或者实际问题是什么？异常堆栈跟踪似乎没有任何帮助。

我的问题是本地防火墙导致了问题。我还发现我可以将证书安装到Java的可信根存储中

请注意，每个Java版本（JDK和JRE）都有自己的“cacerts”文件。请确保安装到适合您的开发或运行时环境的正确版本。我的头撞在墙上，因为在我意识到这一点之前，它在IntelliJ中不起作用

删除代码的密钥库部分

以下是将证书安装到正确位置后对我的代码所做的更改

public static void main(String[] args) throws Exception {
    ChatClient chatclient = new ChatClient("wss://thomas.localnetwork.com:65120/wsserver?userId=Thomas", "Thomas", "1", "1", "L");

    chatclient.connectBlocking();

    BufferedReader reader = new BufferedReader( new InputStreamReader( System.in ) );
    while ( true ) {
        String line = reader.readLine();
        if( line.equals( "close" ) ) {
            chatclient.closeBlocking();
        } else if ( line.equals( "open" ) ) {
            chatclient.reconnect();
        } else {
            chatclient.send( line );
        }
    }
}
