Spring与休眠连接池
您可以使用DBCP组件
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="initialSize" value="10" />
<property name="maxActive" value="5" />
<property name="maxWait" value="5000" />
</bean>
<!-- Hibernate Configuration -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
p:dataSource-ref="dataSource">
<property name="annotatedClasses">
<list>
<value>com.project.domain.Domain1</value>
<value>com.project.domain.Domain1</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
${hibernate.dialect}
</prop>
<prop key="hibernate.show_sql">
${hibernate.show_sql}
</prop>
<prop key="hibernate.generate_statistics">
${hibernate.show_statistics}
</prop>
</props>
</property>
</bean>
在DBCP的时刻实际版本是'org.apache.commons.dbcp2.BasicDataSource' – Andremoniy 2017-04-19 09:00:46
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="url" value="<put database connection url here>" />
<property name="username" value="XXXXXX" />
<property name="password" value="XXXXXXXX" />
<property name="driverClassName" value="<database driver here>" />
</bean>
<bean id="pool" class="org.apache.commons.pool.impl.GenericObjectPool">
<property name="minEvictableIdleTimeMillis"><value>300000</value></property>
<property name="timeBetweenEvictionRunsMillis"><value>60000</value></property>
</bean>
<bean id="dsConnectionFactory" class="org.apache.commons.dbcp.DataSourceConnectionFactory">
<constructor-arg><ref bean="dataSource"/></constructor-arg>
</bean>
<bean id="poolableConnectionFactory" class="org.apache.commons.dbcp.PoolableConnectionFactory">
<constructor-arg index="0"><ref bean="dsConnectionFactory"/></constructor-arg>
<constructor-arg index="1"><ref bean="pool"/></constructor-arg>
<constructor-arg index="2"><null/></constructor-arg>
<constructor-arg index="3"><null/></constructor-arg>
<constructor-arg index="4"><value>false</value></constructor-arg>
<constructor-arg index="5"><value>true</value></constructor-arg>
</bean>
<bean id="pooledDS" class="org.apache.commons.dbcp.PoolingDataSource" depends-on="poolableConnectionFactory">
<constructor-arg><ref bean="pool"/></constructor-arg>
</bean>
如果您想使用最佳所有Java连接池提供商之间尝试HikariCP。 配置在servlet的环境中使用HikariCP作为数据源的bean:
<beans:bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
<beans:property name="dataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlDataSource"/>
<beans:property name="maximumPoolSize" value="5" />
<beans:property name="maxLifetime" value="30000" />
<beans:property name="idleTimeout" value="30000" />
<beans:property name="dataSourceProperties">
<beans:props>
<beans:prop key="url">jdbc:mysql://localhost:3306/exampledb</beans:prop>
<beans:prop key="user">root</beans:prop>
<beans:prop key="password"></beans:prop>
<beans:prop key="prepStmtCacheSize">250</beans:prop>
<beans:prop key="prepStmtCacheSqlLimit">2048</beans:prop>
<beans:prop key="cachePrepStmts">true</beans:prop>
<beans:prop key="useServerPrepStmts">true</beans:prop>
</beans:props>
</beans:property>
</beans:bean>
然后用这个数据源创建EntityManagerFactory的豆。 与示例项目完整示例下载可以在链接中找到:http://frameworkonly.com/hikaricp-connection-pooling-in-spring-hibernate-jpa/
虽然这个链接可能回答这个问题,最好在这里包含答案的重要部分,并提供参考链接。如果链接页面更改,则仅链接答案可能会失效。 – Ram 2015-07-07 14:58:35
