如何将Spring WebSocketClient与SSL一起使用？

Question

WebSocketClient transport = new StandardWebSocketClient();
WebSocketStompClient stompClient = new WebSocketStompClient(transport);
stompClient.setMessageConverter(new MappingJackson2MessageConverter());
String url = cfg.getWebsocketEndpoint();
StompSessionHandler handler = new MySessionHandler();
WebSocketHttpHeaders headers = new WebSocketHttpHeaders();
stompClient.connect(url, handler);

sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

    String keystoreType = "JKS";
    InputStream keystoreLocation = new FileInputStream("src/main/resources/aaa.jks");
    char [] keystorePassword = "zzz".toCharArray();
    char [] keyPassword = "zzz".toCharArray();

    KeyStore keystore = KeyStore.getInstance(keystoreType);
    keystore.load(keystoreLocation, keystorePassword);
    KeyManagerFactory kmfactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    kmfactory.init(keystore, keyPassword);

    InputStream truststoreLocation = new FileInputStream("src/main/resources/aaa.jks");
    char [] truststorePassword = "zzz".toCharArray();
    String truststoreType = "JKS";

    KeyStore truststore = KeyStore.getInstance(truststoreType);
    truststore.load(truststoreLocation, truststorePassword);
    TrustManagerFactory tmfactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    tmfactory.init(truststore);

    KeyManager[] keymanagers = kmfactory.getKeyManagers();
    TrustManager[] trustmanagers =  tmfactory.getTrustManagers();

    SSLContext sslContext = SSLContext.getInstance("TLS");
    sslContext.init(keymanagers, trustmanagers, new SecureRandom());
    SSLContext.setDefault(sslContext);

更新：不幸的是，我没能用自定义TrustStore做到这一点。我用installCert.java安装了证书。

我认为每个websocket容器实现都提供了实现这一点的方法。必须使用StandardWebSocketClient.setUserProperties设置此配置。所有这些属性都在客户端使用的ClientEndpointConfig中进行内部设置。

下面是一个使用Tomcat作为提供程序的示例：

StandardWebSocketClient wsClient = //...;
SSLContext sslContext = //...;
wsClient.setUserProperties(WsWebSocketContainer.SSL_CONTEXT_PROPERTY, sslContext);

在任何情况下，您都应该参考提供程序参考文档，以了解应该使用哪些配置键。
