weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection
用支付宝的sdk第三方jar包alipay-sdk-java20161213173952.jar，测试当面付demo时，用tomcat启动没有问题，而在使用weblogic（我使用的是Oracle WebLogic Server 12c R2 (12.2.1.2)版本），报错结果如下：
Error 500--Internal Server Error |

原因是weblogic默认是是返回SOAPHttpsURLConnection类型的对象,无法进行强转。
解决方法：在startWebLogic.cmd（windows系统）文件中添加
setJAVA_OPTIONS=%SAVE_JAVA_OPTIONS% -DUseSunHttpHandler=true，
即可
