此錯誤很少發生。如果我再次刷新頁面，我沒有發現任何錯誤。HTTP狀態500 - 處理JSP頁面發生異常（休眠）

你不應該在同一個文件中混用dao，jsp等。 – Alex

爲什麼我們不應該混合？ – SKR

此錯誤只能通過修復Web服務器軟件來解決。這不是客戶端問題。 Web服務器站點的運營商應該定位和分析日誌，以提供有關錯誤的更多信息。 或 不要把src文件夾放在WEB-INF目錄下！

似乎有你的應用服務器和數據庫服務器之間的連接問題（你的數據庫服務器不是由應用服務器可達）：

Can not read response from server. Expected to read 4 bytes, read 0 bytes before connection was unexpectedly lost.

或

Communications link failure. 

The last packet successfully received from the server was 430,396 milliseconds ago. The last packet sent successfully to the server was 0 milliseconds ago.

看看this發佈有關如何解決此問題的更多信息。
