Question

我有一个连接到Web的Java多线程应用程序。在我启动一些线程后，如果我从可执行jar运行它，应用程序挂起。如果我从Eclipse运行它，它可以很好地工作。

这是连接到网络的说明：

Jsoup.connect(url).header("Cache-Control", "no-cache").header("User-Agent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0").header("Connection", "keep-alive").get();

这些是我从jar中运行的例外情况：

为什么会这样？怎么解决？为什么jar和IDE之间存在这种不同的行为？

Eclipse控制台输出：https://text-share.com/view/22a1e492
Dos控制台输出：https://text-share.com/view/a684f1bd他们似乎做同样的事情......？

Answer 1

请使用以下两种方式运行：-Djavax.net.debug = all flag以获取更多详细信息。尝试比较eclipse和JAR之间运行的应用程序的所有JVM参数。

可能有很多原因，也许eclipse具有从Jar运行时未设置的特定配置。

Java连接从jar失败但是从Eclipse工作
