BoneCP is a fast, free, open-source, Java database connection pool (JDBC Pool) library. If you are familiar with C3P0 and DBCP then you already know what this means. For the rest, this is a library that will manage a database connection for you to get faster database access in your application.
BoneCP is fast! For some tests, it's almost 25 times faster than the next fastest connection pool option, not to mention that BoneCP never spin-locks so it won't slow down your application.

使用DataSource

try {
connection.close();

}
在Hibernate中使用BoneCP
在Hibernate中使用BoneCP除了需要上面提到的jar包之外，還需要下載一個名為bonecp-provider-0.7.0.jar的bonecp-provider的jar包，它的下載位置是：http://jolbox.com/bonecp/downloads/maven/com/jolbox/bonecp-provider/0.7.0/bonecp-provider-0.7.0.jar。
除此之外，還需要做如下配置：
-
- <bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean" autowire="autodetect">
- <property name="hibernateProperties">
- <props>
- <prop key="hibernate.connection.provider_class">com.jolbox.bonecp.provider.BoneCPConnectionProvider</prop>
- <prop key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>
- <prop key="hibernate.connection.url">jdbc:mysql://127.0.0.1/yourdb</prop>
- <prop key="hibernate.connection.username">root</prop>
- <prop key="hibernate.connection.password">abcdefgh</prop>
- <prop key="bonecp.idleMaxAge">240</prop>
- <prop key="bonecp.idleConnectionTestPeriod">60</prop>
- <prop key="bonecp.partitionCount">3</prop>
- <prop key="bonecp.acquireIncrement">10</prop>
- <prop key="bonecp.maxConnectionsPerPartition">60</prop>
- <prop key="bonecp.minConnectionsPerPartition">20</prop>
- <prop key="bonecp.statementsCacheSize">50</prop>
- <prop key="bonecp.releaseHelperThreads">3</prop>
- </props>
- </property>
- </bean>
xml方式配置bonecp
<?xml version="1.0" encoding="UTF-8"?>
<bonecp-config>
<default-config>
<property name="jdbcUrl">jdbc:oracle:thin:@127.0.0.1:1521:orcl</property>
<property name="username">scott</property>
<property name="password">tiger</property>
<property name="partitionCount">3</property>
<property name="maxConnectionsPerPartition">30</property>
<property name="minConnectionsPerPartition">10</property>
<property name="acquireIncrement">3</property>
</default-config>
