java.lang.NoClassDefFoundError：javax/servlet/ServletContext

Question

我剛剛從14.1升級到IntelliJ 15.0（我很着急，忘記保存以前的插件狀態爲14.1），我試圖配置一般的運行/使用Gradle在Intellij中使用Spring Boot調試配置設置。在配置選項卡中，我添加了1）Main類，2）JRE和3）IntelliJ中模塊的類路徑。我使用Spring Boot作爲選定的配置。然而，當選擇來看，我得到這個錯誤：這裏

Answer 1

OK是我必須做的來解決這個具體問題：的IntelliJ需要有一個定義搖籃任務調試/運行配置中調用bootRun。這使我現在可以在IntelliJ中運行後端代碼或調試後端代碼更新。 2）接下來，我必須重構我的IntelliJ目錄，因爲IntelliJ 15已經安裝了父和子JRE文件夾，這是不正確的，因此IntelliJ顯示和異常聲明它找不到a）java.exec和b）jvm。它的JRE/Lib子目錄下的cfg文件。一旦我解決了這兩個問題，構建和調試似乎都適用於Java Spring後端。我跟隨了IntelliJ關於奇怪的JRE安裝。

Answer 2

有同樣的問題。似乎特定於嘗試通過IntelliJ 15.x 運行配置來運行Spring Boot Web應用程序。由於我使用的是maven，我改爲創建了maven運行配置，將command line action指定爲spring-boot:run - 這適用於運行和調試模式。附上截圖。
