重新启动PC后，Eclipse Webapp项目无法在Tomcat上正常启动

当我关闭PC时，我已配置并正在运行一个Web应用程序。然后，当我开始时，奇怪的事情开始发生：我使用eclipse indigo

ee。它为我提供了一个类未找到的异常，该类位于正确的位置，我没有进行任何修改，我想在修改它之前重新运行该应用程序。在另一个项目中，它无法识别字符串类型，因此我重新加载了项目，然后程序包出现问题，然后删除并替换了程序包，它可以正常工作。这个项目很好。但是我正在研究的另一个人却说找不到一个类。我将其放在另一个包装中，然后放回原处。错误消失了。但是出现了一个新的控制台，这是我的控制台输出：

回答：

显然环境很脏。我建议清理并重建所有。

  1. 从Tomcat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. 清洁Tomcat（右键单击Tomcat， 清洁 ）

  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…”>在下面清理选定的项目，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， 单击“开始” ）。

不可能找出导致此问题的真正原因，可能的因素太多。例如，工作区未正确关闭，或者Tomcat未正确关闭，或者您同时执行了“太多”操作，从而导致Eclipse等后台任务中出现竞争状况。这与Eclipse

+ Tomcat组合没有明确关系。根据我的经验，在使用JBoss AS和Glassfish服务器时也会发生这种情况。
