java - SSL java.security.NoSuchAlgorithmException

Question

Java 表示在这一行中，找不到文件 ssc.store:

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

(服务器是一个ServerSocket)

我尝试使用包含此代码的库，但无法打开此 ServerSocket。

完全错误

问题是什么？

Answer 1

您需要运行代码的工作目录中的 ssc.store 文件。商店在这里:https://github.com/DeBukkIt/SimpleServerClient/blob/master/ssc.store (或在您 checkout 的特定分支或标签中)。

例如，如果您在 IntelliJ 中运行 main 方法，存储文件应该位于项目根目录中。或者，如果将应用程序打包到 jar 中并运行 java -jar yourapp.jar，则 ssc.store 应该位于同一目录中作为 jar 文件。
