删除并重新安装Spring PetClinic示例应用程序后，tomcat 7服务器将无法启动

标签： java eclipse spring tomcat spring-mvc

我一直在研究Spring Pet Clinic样本应用程序，通过深入剖析并制作大量流程图。在操作它之后，我决定将其删除并重新安装，以便我可以使用原始应用程序进行新的实验。因此，我在eclipse项目浏览器中右键单击了petclinic应用程序并将其删除，指示eclipse也删除了计算机上的文件。然后我跟着the instructions in the answer from Sotirios Delimanolis重新下载并重新安装了这个uri的宠物诊所应用程序：

https://github.com/SpringSource/spring-petclinic.git

问题在于，在我按照说明并单击“运行为...在服务器上运行”之后，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，并且我还在此过程中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petclinic项目并输入run as ...在服务器上运行时，有人能告诉我如何让它正常运行吗？

以下是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 ...在服务器上运行时，tomcat 7正常启动。只有当我尝试在eclipse中运行服务器上的petclinic应用程序时，才会发生tomcat 7无法启动的错误。

编辑：

pom.xml在其依赖项中包含以下内容：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring-framework.version}</version>
</dependency>

答案 0 :(得分：1)

这有时会发生在Eclipse的Maven插件中。出于某种原因，在创建运行应用程序的类路径条目时，它会将其依赖关系映射到正确的文件夹（即库路径）。在这种情况下，未正确设置类路径，并获得ClassNotFoundException s。

通常可以通过强制Maven重新启动Eclipse或删除包含所有下载的jar的.m2文件夹来重新计算/设置其路径来解决此问题。此文件夹通常位于Windows的“用户”文件夹下，C:/Users/your.name。
