Spring中对于Hibernate的治理

Spring中对于Hibernate的管理

jdbc.properties文件：

 

driverClassName=org.gjt.mm.mysql.Driver
url=jdbc\:mysql\://localhost\:3306/db_student?useUnicode\=true&characterEncoding\=UTF-8
username=root
password=root
initialSize=1
maxActive=500
maxIdle=2
minIdle=1

 

applicationContext.xml:

		<!-- 最大空闲值.当经过一个高峰时间后，连接池可以慢慢将已经用不到的连接慢慢释放一部分，一直减少到maxIdle为止 -->
		<property name="maxIdle" value="${maxIdle}" />
		<!--  最小空闲值.当空闲的连接数少于阀值时，连接池就会预申请去一些连接，以免洪峰来时来不及申请 -->
