如何通过SSL实现RESTful服务？

在Eclipse中运行RESTful客户端时，出现以下错误：

java.net.ConnectException: Connection refused: connect
    at java.net.PlainSocketImpl.socketConnect(Native Method)
    at java.net.PlainSocketImpl.doConnect(Unknown Source)
    at java.net.PlainSocketImpl.connectToAddress(Unknown Source)
    at java.net.PlainSocketImpl.connect(Unknown Source)
    at java.net.SocksSocketImpl.connect(Unknown Source)

    at sun.net.www.protocol.https.HttpsURLConnectionImpl.getOutputStream(Unknown Source)
    at com.elkay.client.RestClient.main(RestClient.java:23)

也试着这样做。 //在标头中设置基本身份验证

 String userPassword = "password"; 
 String encoding = new sun.misc.BASE64Encoder().encode(userPassword.getBytes()); 
 conn.setRequestProperty("Authorization", "Basic " + encoding); 
 String parameters = "username=" + URLEncoder.encode("user1", "UTF-8") + "&password=" + URLEncoder.encode("user1password", "UTF-8"); 
 printout.writeBytes (parameters);

编辑。请查收。我没有使用球衣或CFX。就是这个简单的客户端。为什么要使用HttpUrlConnection。您应该使用HttpsUrlConnection。此外，证书是否已添加到您的受信任存储中？已尝试使用HttpsUrlConnection。此外，您能否简要介绍如何创建受信任存储，即.jks文件？因为我可以直接在浏览器中调用URL，所以它不会因为使用HTTPS而被阻止。注意：不是确切的URL，但同样。请在下一个答案中输入代码。您可以从iE的.cer的Mozilla浏览器中生成.crt。您在这两行中尝试了什么？String authString=URLEncoder.encode（“username=anushree&password=anushree”，“UTF-8”）；printout.writeBytes（authString）；
