【中文标题】无法从静态上下文中引用非静态方法 getSocketFactory [重复]

【英文标题】：Non-static method getSocketFactory cannot be referenced from a static context [duplicate]

【问题描述】：

我的代码给出了上述错误，因为无法从静态上下文引用非静态方法 getSocketFactory。将 trustAllHost 更改为非静态也没有起作用。

WebSocketClient(URI serverUri, String topic, Map<String, String> headers) 
        super(serverUri, headers);
        if (serverUri.toString().contains("wss://"))
            trustAllHosts(this);
        this.topic = topic;
    

    static void trustAllHosts(MCPWebSocketClient appClient) 
        TrustManager[] trustAllCerts = new TrustManager[]new X509TrustManager() 
            public java.security.cert.X509Certificate[] getAcceptedIssuers() 
                return new java.security.cert.X509Certificate[];
            

            @Override
            public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException 
                // TODO Auto-generated method stub

            

            @Override
            public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException 
                // TODO Auto-generated method stub

            
        ;

        try 
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            final SSLSocketFactory factory = SSLContext.getSocketFactory(); //this line
            appClient.setSocket(factory.createSocket());
            appClient.connectBlocking();
         catch (Exception e) 
            e.printStackTrace();
        
    

【参考方案1】：

getSocketFactory() 是一个非静态方法。您需要一个 SSLContext 对象来调用 getSocketFactory() 方法。因为您已经创建了 SSLContext 的对象 所以调用

sc.getSocketFactory();

而不是

SSLContext.getSocketFactory();
