子實體的參數和數據表的詳細信息

Question

我正在編寫一個 Java EE 應用程序來對公司員工進行年度評估。 當我單擊“詳細信息”時，我想顯示每個協作者的評估詳細信息。

3 個受影響的表是“Collaborateur”、“Entretien”和“NoteEntretien”

因此，當我選擇一個合作者並單擊查看詳細信息時，我希望被重定向到一個新頁面，其中包含表單上的合作者詳細信息，並在帶有他的評估的數據表之后。 當我點擊評估細節時，我應該被重定向到另一個頁面，其中包含評估的不同注釋。

我在前端使用帶有 Primefaces 5.0 的 JSF 2.x，在持久性上使用 EclipseLink，在業務端使用 EJB 3.1。

我已經有了解決方案，可以在沒有帶有協作者評估的數據表的情況下在彈出窗口中顯示協作者詳細信息。

請幫助我找到最好的方法來做到這一點。

謝謝！

這是一個復雜的問題。 沒有“最佳解決方案”。 我只是可以推薦一些實現它的方法。

准備一個帶有 URL 和控制器CollaborateurDetailController的單獨模板頁面。
在該控制器的init()方法中，從 URL 中獲取"id"參數，並通過該控制器的"Selected"的 id 獲取編輯后的實體。 或者，如果沒有"id" ，則創建一個新實例。
更改列表中編輯按鈕上的偵聽器，以重定向到帶有"id"參數的新控制器頁面，或重定向到創建按鈕的空白頁面。

我建議為細節制作單獨的控制器。 在成熟的項目中，您將需要詳細實現復雜的表單和組件。 模態窗口是一個基本的解決方案，在很多情況下，您將來只需要重構即可。
