java - Spring MVC 项目在终端上运行但在 Intellij 上运行时出错

Question

我有一个应该部署在 Tomcat 服务器上的 Spring MVC Web 应用程序。当我从终端运行它时它被部署，即 maven 构建，然后将 .war 文件复制并粘贴到 Tomcat 的 webapps 文件夹中。但是，当我使用 Smart Tomcat 插件在 Intellij 中构建和运行相同的应用程序时，出现 NullPoiinterException 错误。我不知道如何调试它。我是 Spring MVC 的新手。我附上了 stacktract.txt 文件。

Answer 1

这个错误出现在第三方Smart Tomcat插件，你应该report it here .

Disabling该插件应该有所帮助。在 IntelliJ IDEA Ultimate 中使用内置的 Tomcat 集成。
