S2SH配置proxool连接池

1、用连接池的话，就不用配置dataSource数据源了,需要的jar包 proxool-cglib.jar 和proxool-0.9.1.jar

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="mappingDirectoryLocations"> <list> <value>classpath:com/beckham/model</value> </list> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect"> org.hibernate.dialect.MySQLDialect </prop> <prop key="hibernate.show_sql">true</prop> <!-- 配置proxool连接池 --> <prop key="hibernate.proxool.pool_alias">DBPool</prop> <prop key="hibernate.proxool.xml">proxool.xml</prop> <prop key="hibernate.connection.provider_class"> org.hibernate.connection.ProxoolConnectionProvider </prop> <!-- 设置缓存 --> <prop key="hibernate.cache.use_query_cache ">true</prop> <prop key="hibernate.cache.use_second_level_cache">true</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop> <prop key="hibernate.cache.configurationResourceName">ehcache.xml</prop> <prop key="hibernate.connection.autocommit">true</prop> </props> </property> </bean>

2、在src目录下新建proxool.xml文件

<?xml version="1.0" encoding="UTF-8" ?> <something-else-entirely> <proxool> <alias>DBPool</alias> <driver-url>jdbc:mysql://localhost:3306/menhu</driver-url> <driver-class>com.mysql.jdbc.Driver</driver-class> <driver-properties> <property name="user" value="root"/> <property name="password" value="root"/> </driver-properties> <!-- 最小的数据库连接数 --> <minimum-connection-count>10</minimum-connection-count> <!-- 最大的数据库连接数 --> <maximum-connection-count>50</maximum-connection-count> <!-- 最少保持的空闲连接数 --> <prototype-count>10</prototype-count> <!-- 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。 --> <house-keeping-sleep-time>90000</house-keeping-sleep-time> <!-- 指因未有空闲连接可以分配而在队列中等候的最大请求数,超过这个请求数的用户连接就不会被接受 --> <maximum-new-connections>300</maximum-new-connections> <!-- 某一时间点的最大连接数 --> <simultaneous-build-throttle>150</simultaneous-build-throttle> <!-- 一个线程持有一个连接的最长时间5分钟，单位毫秒(默认5分钟) --> <maximum-active-time>300000</maximum-active-time> <!-- 一个连接的最长活动时间4小时，单位毫秒(默认4小时) --> <maximum-connection-lifetime> 14400000 </maximum-connection-lifetime> <house-keeping-test-sql> set names 'UTF-8'; </house-keeping-test-sql> </proxool> </something-else-entirely>
