java.lang.ClassNotFoundException：javax.servlet.ServletContainerInitializer

Question

我正在編寫一些servlet並且它們都運行良好Tomcat沒有運行什么問題。 然后我編寫了一個使用JERSEY的類文件，當我嘗試運行它時，Tomcat無法啟動。 我在Eclipse中安裝了Web開發工具插件，每次我點擊編譯我都會

java.lang.ClassNotFoundException：javax.servlet.ServletContainerInitializer

這是控制台的輸出

這是怎么造成的，我該如何解決？

Answer 1

javax/servlet/ServletContainerInitializer是Servlet 3.0一個類，在Tomcat 6中不支持。

你可能有servlet.jar漂浮在CLASSPATH的某個地方，它不應該。 這真的會弄亂類加載器，因為Tomcat的類加載器沒有像預期的那樣正常運行（參見上面的鏈接）。 servlet.jar只能在$CATALINA_HOME/lib找到一次。

Answer 2

有時，如果您在Eclipse中運行Tomcat服務器，則本地Tomcat工作目錄可能會被抬高，您必須明確清除它。 請注意，這與在項目上執行Clean構建不同：從“服務器”窗口：右鍵單擊要嘗試啟動的服務器 - >清除Tomcat工作目錄...->確定

Answer 3

簡單點擊tomcat服務器然后清理tomcat工作目錄然后清理tomcat。 它會工作。

Answer 4

我今天也遇到了同樣的問題。 最終結果是用戶庫變空了。 但是，顯示的錯誤消息沒有給出任何提示。

Answer 5

遲到的答案，但這可能有助於某人。

我相信這是因為Jersey是使用較新的java版本創建的，並且您嘗試在較舊版本的java中運行它。 更新您的Java版本或下載支持您的Java版本的舊版Jersey。

Window -> Preferences -> Java -> Compiler -> set "Compiler compliance level" to 1.7. 

來自Jersey文檔：

Until version 2.6, Jersey was compiled with Java SE 6. This has changes in Jersey 2.7. 
Now almost all Jersey components are compiled with Java SE 7 target. It means, that 
you will need at least Java SE 7 to be able to compile and run your application 
that is using latest Jersey. Only core-common and core-client modules are still 
compiled with Java class version runnable with Java SE 6.
