使用jar庫自動部署應用

Question

我嘗試使用eclipse和maven作為依賴項解析器來部署Web應用程序。 但我看到例外：

我找到了解決此問題的方法： JBOSS 7-Spring ContextLoaderListener ClassNotFoundException

這很奇怪，因為..

理論上可以解決此問題，但是昨天，我在同一服務器上使用相同的設置和相同的jar開發了相同的應用程序，並且使用maven提取了相同的jar，沒有任何實例。

我想問一下如何解決沒有copy-pase .jar文件的問題。 以及如何在沒有手動（明確）用戶干預的情況下自動執行此操作。

我只想做：

• 建立專案
• 使用m2e解決依賴關系
• 並使用run在jboss進行部署

Answer 1

您需要研究java類路徑。 當您的應用程序要求類時，這些類必須可供類加載器加載。

通常對於Web應用程序，這意味着需要將包含類的jar打包到WAR的/ WEB-INF / lib目錄中。

使用Maven，您應該使用包裝類型war ，而不是jar 。 然后，Maven的war插件（即http://maven.apache.org/plugins/maven-war-plugin/usage.html ）將自動將所有依賴項打包到war的lib文件夾中。

要使用m2e解決依賴關系，您應該

• 確保項目使用maven從命令行編譯和打包
• 從eclipse中刪除項目（不要刪除文件）
• 刪除日食元數據文件（即.project，.classpath，.settings）
• 日食
• 導入->導入現有的Maven項目->選擇您的項目

此時，m2e將為您創建所有的eclipse設置，包括動態的類路徑庫。
