調度程序初始化失敗，Struts2

Question

我正在用Struts2構建我的第一個Web應用程序。我沒有發現錯誤（當然，我不認爲我犯了錯誤），但Tomcat總是給我404 ...

我在這裏發佈日誌給你，建議我一個解決方案。但它對我沒有多大幫助，只是說他沒有加載配置或bean。我真的不知道。

Answer 1

java.lang.ClassNotFoundException: org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter 

意味着struts2-core.x.x.x.jar應該在類路徑，例如在WEB-INF/lib。

Answer 2

您當前正在加載您沒有所需依賴關係的S2插件。

你缺少依賴關係。

1. 只部署您實際使用的S2插件。
2. 包含您實際使用的插件的依賴關係。
3. 你仍然需要S2庫和它們的依賴關係來完成任何工作。

這就是爲什麼你應該考慮使用像Maven，Gradle，Ivy等一樣的依賴管理工具的一個原因。手動跟蹤傳遞依賴是最不愉快的。

Answer 3

以防萬一任何人有同樣的問題。在項目構面上將java版本更改爲1.7或更高版本。
