Question

我是Web服务的新手。我接手了另一个开发人员的一些开发项目。一切都很好，直到我创建了自己的测试项目，看看一切是如何组合在一起的。当我从测试项目恢复到之前的工作项目时，项目会编译但在部署期间不会启动。我甚至不知道从哪里开始寻找。

我正在使用Eclipse Kepler并部署到WildFly服务器。

日志显示以下错误消息：

我解决了与您的问题非常相似的问题。

错误日志实际上会告诉您在哪里查看，它实际上表示您的 jdbc-driver 缺失。 WildFly服务器部署文件夹中缺少文件 sqljdbc4.jar 。您需要将jar文件添加到<your_wildfly_server_folder> --> standalone --> deployments。添加丢失的jar文件后，部署对我来说没问题。

我已经意识到（至少在我的情况下）我的部署尝试之一WildFly服务器上的垃圾收集器出了问题。这将导致在服务器上取消部署所需的jar文件（在您的情况下为 sqljdbc4.jar ）。由于这是您自己的应用程序的依赖项，部署您的应用程序将无法正常工作。

如果您看到 deployments 文件夹中存在jar文件，但仍然无法部署应用程序，则需要先重新部署jar文件。您可以从WildFly管理控制台执行此操作，但我还没有找到确切的结果。您也可以通过转到 deployments 文件夹，找到一个名为您丢失的jar文件的文件但扩展名为.undeployed的文件（在您的情况下为 sqljdbc4.jar.undeployed ），然后删除它。如果一切顺利，那么WildFly将自动重新部署您的jar文件。
