SSH框架的項(xiàng)目在訪問數(shù)據(jù)庫(kù)的時(shí)候，訪問完成后一直占用鏈接，不釋放，導(dǎo)致過(guò)了一段時(shí)間后，服務(wù)器沒掛，就是有訪問數(shù)據(jù)庫(kù)的連接是時(shí)候，一直卡住.

這里為您提供的是一個(gè)經(jīng)過(guò)優(yōu)化的SSH整合連數(shù)據(jù)庫(kù)實(shí)例，用于數(shù)據(jù)庫(kù)連接的SSH整合代碼。

ssh項(xiàng)目中，隨著項(xiàng)目的啟動(dòng)spring會(huì)建立數(shù)據(jù)庫(kù)連接池。

SSH整合連數(shù)據(jù)庫(kù)實(shí)例

1.配置spring對(duì)應(yīng)的hibernate文件：

<prop key="hibernate.connection.release_mode">after_statement</prop> 事務(wù)提交后自動(dòng)釋放連接

2配置事務(wù)
