我有一些关于为我的 Web 服务建立 SSL 连接的问题。所以我用CXF的工具“WsdlToJava”生成了一个java web服务项目。现在我不想使用我的 Web 服务，该服务托管在我的服务器上，具有 SSL 协议访问权限。
当我尝试关注此页面如何为 SOAP 客户端配置 HTTPConduit 时，我遇到了一些 SSL 问题。我替换了这部分：
URL wsdl = getClass().getResource("wsdl/greeting.wsdl");
SOAPService service = new SOAPService(wsdl, serviceName);
Greeter greeter = service.getPort(portName, Greeter.class);
经过 ：
URL WSDL_LOC = new URL("https://myserver.com/ws/myWS?wsdl");
MyWS_Service myws_serv = new MyWS_Service(WSDL_LOC);
MyWS mywebservice = myws_serv.getMyWSSOAP();
但由于 SSL 原因，它在此代码的第二行失败。在本教程中，在这部分之后建立了 SSL 连接，我认为他们没有问题，因为他们的示例没有尝试在某些服务器上获取 wsdl 文件，而是在本地获取。
在获取 WSDL 文件之前，我需要做什么来建立 SSL 连接？谢谢你
