我一直在通过深入剖析并制作大量流程图来研究 Spring Pet Clinic 示例应用程序。在操作了这么多之后，我决定删除它并重新安装它，以便我可以对原始应用程序进行新的实验。因此，我在eclipse项目资源管理器中的petclinic应用程序上右击删除，指示eclipse也删除电脑上的文件。然后我按照Sotirios Delimanolis 的回答中的说明从这个 uri 重新下载并重新安装宠物诊所应用程序：
https://github.com/SpringSource/spring-petclinic.git
问题是，在我按照说明操作并单击“以...在服务器上运行”后，eclipse 告诉我 tomcat 7 服务器无法启动。我已经使用相同的说明重复了几次卸载和重新安装 petclinic 应用程序的过程，并且在此过程中我还关闭并重新启动了我的计算机。但错误仍然存在。
当我右键单击宠物诊所项目并键入 run as...run on server 时，谁能告诉我如何让它正常运行？
这是 Eclipse 控制台中的完整堆栈跟踪：

请注意，当我在 Eclipse 中右键单击 OTHER 应用程序并选择 run as...run on server 时，tomcat 7 启动正常。仅当我尝试从 Eclipse 中在服务器上运行 petclinic 应用程序时，才会出现 tomcat 7 无法启动的错误。
