有人可以指导一下我在这里犯的错误.我不确定是否需要粘贴源代码.
这是因为您正在将应用程序的新实例部署到服务器,但先前实例的某个线程或连接尝试执行您编写的某些业务逻辑.这就是为什么,JVM的主要部分叫做ClassLoader,告诉你"非法访问:这个Web应用程序实例已经停止"并抛出相应的异常...你可以关闭Application Server的自动部署功能,这在生产环境中是优选的,之后是手动部署应用程序重启服务器.或者你可以在Class级别控制Servlet生命周期:)))在"预部署"期间关闭所有连接或停止一些线程.或者使用复杂的方法使用ManagedExecutorService控制线程.祝好运!!!
你在使用 Netbeans 吗？我有一个类似的错误，只是无法加载oracle.sql.lnxlib。就像许多海报指出的那样，此错误通常与 Tomcat 缓存应用程序的多个实例有关。一位同事通过在 Netbeans 中取消部署应用程序的旧实例，为我解决了这个问题。为此，请转到服务选项卡 > 服务器，然后双击Apache Tomcat 或 TomEE在打开 netbeans 后运行一次应用程序后，应该会出现一个 Web 应用程序文件夹。如果您双击它，您应该会看到您的应用程序实例出现。您应该能够右键单击它们，然后单击取消部署（您可能必须右键单击它们并先点击停止）。最后，在构建和运行应用程序之前，您应该停止然后启动 tomcat。
希望这可以帮助。
