條紋不會去與事件{$事件}

Question

我是新來的條紋，所以我很抱歉，如果它是一個簡單的問題，現在我有這個類綁定嘗試，訪問的ActionBean的網址：

/角色/加

或任何其他事件，我得到了404，我想獲得更多的清潔URL，這樣會更容易在使用彈簧安全功能之前限制動作可以使用的用戶：

@UrlBinding("/role.html") 

和去的網址：

role.html添加

我不知道我在做什麼錯了，請幫幫我，在此先感謝？

Answer 1

我相信這是因爲你有兩個處理方法用於add事件。這將導致條紋失敗，出現以下異常啓動（然後用404所有請求，因爲該servlet未能啓動）

Answer 2

dhensche是正確的，你有太多的添加處理程序您發佈的代碼。

如果我們假設這只是一個複製錯誤，並且您的ActionBean在您的UrlBinding更改之前可用，我想您可能需要查看您的servlet映射配置。

由於您的鏈接將不再包含「.action」，Web請求可能不知道如何到達StripesDispatcher，這就是爲什麼你會得到404響應。

本博客文章有你想要做一個詳細的例子：Clean and usable URLs in Stripes

而且，你可能要考慮命名您的解決方法，以配合他們處理事件，並開溝HandlesEvent註釋。那麼它將不可能意外地定義重複的處理程序。
