[org.hibernate.engine.jdbc.spi.SqlExceptionHelper]:131 IO Error: Connection reset
異常丟擲discard connectionjava.sql.SQLRecoverableException: IO Error: Connection reset 大概意思是資料庫IO錯誤，連線重置
查詢資料得知：
當資料庫連線池中的連線被建立而長時間不使用的情況下，該連線會自動回收並失效，但客戶端並不知道，在進行資料庫操作時仍然使用的是無效的資料庫連線，這樣，就導致客戶端程式報“java.sql.SQLRecoverableException: IO Error: Connection reset” 或“java.sql.SQLRecoverableException 關閉的連線”異常。
有網友給出的避免出現這種情況的方法是
在配置資料來源後面加上
<property name="validationQuery" value="select * from dual"/>
配置後，客戶端在使用一個無效的連線時會先對該連線進行測試，如果發現該連線已經無效，則重新從連線池獲取有效資料庫連線來使用。
具體操作參考網友部落格 解決Caused by: java.sql.SQLRecoverableException: IO Error: Connection reset相關問題
還有網友建議使用啟動時加入以下引數
-Djava.security.egd=file:/dev/../dev/urandom
具體操作參考網友部落格JDBC訪問Oracle資料庫時遇到Connection Reset問題的分析
最簡單的應該是擴大資料庫連線池的最大、最小、空閒連線數等
還有一個異常

..............could not extract ResultSet 這個異常應該是實體類與資料庫的欄位寫法不一致導致的或者是sql中的欄位與資料庫的不一致，主要檢查實體類和資料庫欄位以及SQL
