徹底解決"The last packet successfully received from the server was * milliseconds ago"問題

阿新 • • 發佈：2019-02-14

1.修改mysql 的 wait_timeout引數（和interactive_timeout一起）不推薦

2.如果用hibernate.必須手動配置連線池，最好是用c3p0連線池。如果不配，會使用內建連線池。內建連線池的8小時斷開問題不知道hibernate開發者怎麼還不解決！

3.乾脆不用hibernate,spring的jdbc template+自己配連線池就非常好。
