Spring servlet不可用

我正在用Maven和Hibernate開發基於Spring MVC的應用程序。當我嘗試在Apache服務器上運行它時，Apache服務器在第二行中給我一個錯誤，因爲「Spring Servlet不可用」。這裏是我的POM文件：Spring servlet不可用

這適用於基本的彈簧4，休眠4 MVC應用

你的PostgreSQL dependecy添加到依賴性上面的列表。

我想你現在提到的依賴關係，但我仍然需要添加幾個來完成hibernate和其他依賴項。謝謝user3487063 – 2014-09-02 14:19:13

見我編輯的pom – user3487063 2014-09-02 14:37:26

你好，我用你的舊pom，添加了一些需要的東西，仍然是同樣的錯誤。我的問題已更改爲更新的POM文件。另外，當我直接使用您提供給我的POM文件時，我收到錯誤。你的語法是$ {org.springframework-version}。這種語法不起作用，或者你的意思是我應該手動添加它？ – 2014-09-02 14:43:06

java.lang.ClassNotFoundException當類加載器找不到指定的類時發生。因此，它看起來像您的WAR文件（或者應用程序部署目錄，如果您未部署WAR）在WEB-INF/lib目錄中沒有合適的彈簧JAR（Web應用程序擁有其全部位置建設時會依賴Maven依賴）。

通常您會在應用程序部署目錄中找到你所部署的Web應用程序（爲WAR文件）：

[TOMCAT_HOME]/webapps/[myWebApplication]

如果通過使用Eclipse WTP部署，這個目錄可能會從您的實際Tomcat安裝不同。這將是像

[ECLIPSE_WORKSPACE]/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/[myWebApplication]

您可以通過檢查你的Eclipse Tomcat服務器配置找到確切的目錄，它有一個名爲節「服務器的地址」（在Eclipse服務器選項卡上Tomcat v[Version] Server at localhost雙擊）。
