資源插件提供了有關文件錯誤刪除？

Question

我使用的Grails Groovy和資源插件配置。 我有這樣的場景：

• 我有一個產品，它具有多種圖像。

• 管理員可以刪除任何圖像。

邏輯是，當管理員點擊「刪除」時，我從文件系統中刪除文件（及其縮略文件）。

整個過程平穩運行，但經過一段時間（5-6分鐘）後，當資源插件再次刷新其資源時，它會拋出一個錯誤，提示「某些模塊依賴於資源[path/to/file ]但該文件未找到「。

堆棧跟蹤如下：

資源插件預計，在模塊底層文件不會改變。此外，正被連接到直接由應用程序的任何靜態的資產（而不是通過一個模塊或<克：資源>標記），被認爲是ad-hoc，並加入作爲模塊的資源的上下文。這使得即使是這些「遺留」資產也能被資源插件縮小，編譯，緩存等。

如果您正在使用的文件系統，提供你的這些有點動態資產，你最好從資源插件的Ad-Hoc處理中排除。設置配置標誌grails.resources.adhoc.excludes排除任何目錄您在存儲這些資產。
