用于使用 Web 服务的 SSL 连接

Question

我有一些关于为我的网络服务建立 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，它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How to configure the HTTPConduit for the SOAP Client 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);

作者：

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，我必须做些什么来建立 SSL 连接？ 谢谢

您需要拥有为“https://myserver.com/”颁发证书的签名机构的 CA 证书。最简单的方法是通过网络浏览器获取“https://myserver.com/”的证书，然后检查 CA 层次结构。获得父证书后，将其导入 JKS 信任库。当您运行 java 程序时，将其作为系统属性传递“-Djavax.net.ssl.trustStore=yourtruststore.jks”
