java.lang.NoClassDefFoundError：javax/servlet/ServletContext

Question

我刚刚从14.1升级到IntelliJ 15.0（我很着急，忘记保存以前的插件状态为14.1），我试图配置一般的运行/使用Gradle在Intellij中使用Spring Boot调试配置设置。在配置选项卡中，我添加了1）Main类，2）JRE和3）IntelliJ中模块的类路径。我使用Spring Boot作为选定的配置。然而，当选择来看，我得到这个错误：这里

Answer 1

OK是我必须做的来解决这个具体问题：的IntelliJ需要有一个定义摇篮任务调试/运行配置中调用bootRun。这使我现在可以在IntelliJ中运行后端代码或调试后端代码更新。 2）接下来，我必须重构我的IntelliJ目录，因为IntelliJ 15已经安装了父和子JRE文件夹，这是不正确的，因此IntelliJ显示和异常声明它找不到a）java.exec和b）jvm。它的JRE/Lib子目录下的cfg文件。一旦我解决了这两个问题，构建和调试似乎都适用于Java Spring后端。我跟随了IntelliJ关于奇怪的JRE安装。

Answer 2

有同样的问题。似乎特定于尝试通过IntelliJ 15.x 运行配置来运行Spring Boot Web应用程序。由于我使用的是maven，我改为创建了maven运行配置，将command line action指定为spring-boot:run - 这适用于运行和调试模式。附上截图。
