当我关闭我的电脑时，我配置并运行了一个 Web 应用程序。然后当我开始它时，奇怪的事情开始发生：我使用 eclipse indigo ee。它给了我一个在正确位置的类没有找到异常的类，我没有修改任何东西，我想在修改之前重新运行应用程序。在另一个项目中，它无法识别字符串类型，所以我重新加载了项目，然后包出现问题，然后删除并替换了包，它工作了。那个项目不错。但是我正在研究的另一个说没有找到一个类。我把它放在另一个包裹里，然后放回原处。错误消失了。但是出现了一个新的，这是我的控制台输出：

显然环境很脏。我建议清理并重建所有内容。

  1. 从 Tomcat 中删除项目（右键单击 Tomcat，添加/删除项目，删除项目）
  2. 在 Eclipse 中关闭项目（右键单击项目，关闭）
  3. 清理 Tomcat（右键单击 Tomcat，清理）
  4. 在 Eclipse 中重新打开项目（右键单击项目，打开）
  5. 在 Eclipse 中清理项目（项目>清理...>清理下面的选定项目，选择项目）
  6. 将项目添加到 Tomcat（右键单击 Tomcat，添加/删除项目，添加项目）
  7. 启动 Tomcat（右键单击 Tomcat，开始）。

无法查明导致此问题的真正原因，可能的因素太多。例如，工作区没有正确关闭，或者 Tomcat 没有正确关闭，或者你同时做了“太多”的事情，这导致了 Eclipse 后台任务中的竞争条件等等。这与 Eclipse+Tomcat 组合没有明确关系。在我的经验中，这种情况也时常发生在 JBoss AS 和 Glassfish 服务器上。
