我有一個HtmlUnit依賴關係的Spring MVC應用程序。我在@Component類中使用HtmlUnit實用程序。問題是，經過編譯（根源java.lang.NoClassDefFoundError：組織/阿帕奇/ HTTP/HttpEntity），在瀏覽器啓動（索引頁），我看到的頁面：Spring HtmlUnit依賴關係

如果我從類中刪除@Component註解 - 應用程序不會失敗在啓動時，但實際控制人通話，它使用該類（使用HtmlUni t裏面） - 相同的錯誤。如果我從控制器中刪除使用HtmlUnit的類，一切都很好。 我也嘗試過自己添加庫，而不使用maven - 沒有幫助以太。 關於它的主要祕密是，我的類（使用HtmlUnit）完美地在平常的控制檯應用程序中工作。所以我嘗試了很多東西，我仍然沒有得到這個問題的原因是什麼，爲什麼它不適用於Spring？也許HtmlUnit僅適用於一個線程應用程序？但爲什麼有ClassNotFoundException？
