WildFly 部署失败 - “JBAS014771：缺少/不可用依赖项的服务”

Question

我是 Web 服务新手。我从另一个开发商那里接手了一些开发项目。 一切都工作正常，直到我创建了自己的测试项目来看看一切如何组合在一起。当我从测试项目恢复到之前的工作项目时，该项目可以编译，但在部署期间不会启动。我什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：

Answer 1

我解决了我的问题，与你的问题非常相似。

错误日志实际上确实告诉您去哪里查找，它实际上表明您的 jdbc-driver 丢失了。您的 WildFly 服务器 deployments 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

。添加缺少的 jar 文件后，部署对我来说没问题。

我开始意识到（至少在我的情况下）在我的一次部署尝试中，WildFly 服务器上的垃圾收集器出了问题。这将导致所需的 jar 文件（在您的情况下为 sqljdbc4.jar）在服务器上取消部署。由于这是您自己的应用程序的依赖项，因此部署您的应用程序将不起作用。 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，则需要先重新部署该 jar 文件。您或许可以从 WildFly 管理控制台执行此操作，但我还没有找到具体方法。您还可以通过转到 deployments 文件夹，找到一个与丢失的 jar 文件完全相同但具有 .undeployed 扩展名的文件（在您的情况下为 sqljdbc4.jar.undeployed），然后将其删除。如果一切顺利，WildFly 将自动重新部署您的 jar 文件。
