SSL java.security.NoSuchAlgorithmException

Question

的Java說，在這一行，該文件ssc.store沒有被發現：

server = ((SSLServerSocketFactory) SSLServerSocketFactory.getDefault()).createServerSocket(port); 

（服務器是一個ServerSocket）

我嘗試使用含有此一libary代碼，但我無法打開此ServerSocket。

完全錯誤

問題是什麼？

Answer 1

您需要運行代碼的工作目錄中的ssc.store文件。該店鋪位於：https://github.com/DeBukkIt/SimpleServerClient/blob/master/ssc.store（或者您簽出的特定分店或標籤）。

例如，如果您在IntelliJ中運行main方法，則存儲文件應位於項目根目錄中。或者，如果您將應用程序打包到jar並運行java -jar yourapp.jar，那麼ssc.store應與jar文件位於同一目錄中。
