數據庫連接超時，自動關閉 was active for 315435 milliseconds and has been removed automaticaly

在長時間導出數據時，經常看到一個錯誤，但是沒怎麼影響程序，就一直沒管，今天就把它揪出來

[WARN] #0001 was active for 315435 milliseconds and has been removed automaticaly.
 The Thread responsible was named 'quartz-simpleThreadPoolTaskExecutor-1', 
but the last SQL it performed is unknown because the trace property is not enabled.

 

項目用的spring，配置有proxool連接池，這個問題也不怎麼大，只是因爲操作數據庫超過5分鐘還沒有結束的時候，拋出錯誤意思是proxool連接池把超過309594 milliseconds的連接給關了，這樣配大點就沒問題了
