应用程序通过使用jsf格式读取参数来发送信件。我不明白为什么以及如何解决它，因为当你从开发环境运行时一切正常。 当我将我的应用程序放在VPS服务器上时，我得到了下一个错误堆栈（尽管应用程序可以根据需要在本地主机上运行）：

我创建并编译了使用版本jdk_8u151和JRE的项目。那时，在服务器上，项目是在后来的jre下启动的。使用相同的版本jre解决了这个问题。 TY。
答案 1 :(得分：1)
我认为这是由于您的JRE中未安装Unlimited Strength Java Cryptography Extension而导致的。
尝试在JRE lib / security文件夹中安装（复制JAR）。从here获取。
只需下载并解压缩内容。您应该获得两个文件 local_policy.jar 和 US_export_policy.jar 。将其复制到$JAVA_HOME/jre/lib/security文件夹。
如果这样可以解决问题，您应该考虑升级Java 8版本。此问题已在Java 8u161或更高版本中得到解决。

据我了解，缓存库和添加的库之间存在冲突。所以我试图清理缓存，效果很好。在Android Studio中，您应该尝试“文件”->“使缓存无效/重新启动”。
答案 3 :(得分：0)
在我这边，我卸载了jdk版本，然后安装了最新版本的jdk，它像一个魅力一样起作用。因此，请将您的jre或jdk更新到最新版本，即可解决问题。
