Spring 配置proxool连接池

Spring 配置proxool连接池

在我的工程中，文件名叫hibernate.cfg.xml，和entity放在一起

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> <bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource" destroy-method="close"> <property name="driver" value="${hibernate.driverClass}" /> <!-- 或者直接写成： <property name="driver"> <value>com.mysql.jdbc.Driver</value> </property> --> <property name="driverUrl" value="${hibernate.jbdc.url}" /> <property name="user" value="${hibernate.jbdc.user}" /> <property name="password" value="${hibernate.jdbc.password}" /> <!-- <alias>是连接池的别名，proxoolPool连接池的一种，此外经常使用的连接池还有C3P0 --> <property name="alias" value="proxoolPool" /> <!-- proxool自动侦察各个连接状态的时间间隔(毫秒),侦察到空闲的连接就马上回收,超时的销毁 （默认30秒）--> <property name="houseKeepingSleepTime" value="30000" /> <!-- 最少保持的空闲连接数 （默认5个）--> <property name="prototypeCount" value="20" /> <!-- 设置连接池内生成的最大连接数/在连接池中所有数据库连接的最大数目（默认15个） --> <property name="maximumConnectionCount" value="${hibernate.jdbc.maxConn}" /> <!-- 设置连接池内生成的最小连接数/在连接池中可用的数据库连接的最少数目（默认5个）--> <property name="minimumConnectionCount" value="${hibernate.jdbc.minConn}" /> <!-- 在Consonl中显示sql --> <property name="trace" value="true" /> <property name="verbose" value="true" /> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="schemaUpdate" value="${hibernate.schemaUpdate}" /> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">${hibernate.dialect}</prop> <prop key="hibernate.show_sql">${hibernate.show_sql}</prop> <prop key="hibernate.format_sql">true</prop> <prop key="hibernate.use_outer_join">true</prop> <prop key="hibernate.jdbc.fetch_size">50</prop> <prop key="hibernate.jdbc.use_streams_for_binary">true</prop> <prop key="hibernate.bytecode.use_reflection_optimizer">true</prop> <prop key="hibernate.query.substitutions">true 1,false 0,yes 'Y',no 'N'</prop> </props> </property> <property name="annotatedClasses"> <list> <value>com.mysteel.entity.xxx</value> </list> </property> </bean> <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory" /> </bean> </beans> 

第二个bean即从 <bean：id="sessionFactory"...>到</bean>是因为使用 Spring 框架，可以使用 AnnotationSessionFactoryBean 类轻松建立一个基于注释的 Hibernate 会话工厂
