最近在學習公司的框架，涉及到連線資料庫部分的技術時，發現用的是BoneCP，上網查閱了相關資料與例子，個人覺得下面這例子比較容易懂，有收藏的價值存在，故將其放在自己的部落格裡，供學習時參考： 

BoneCP is a fast, free, open-source, Java database connectionpool (JDBC Pool) library. If you are familiar with C3P0 and DBCPthen you already know what this means. For the rest, this is alibrary that will manage a database connection for you to getfaster database access in your application.
BoneCP is fast! For some tests, it's almost 25 times faster thanthe next fastest connection pool option, not to mention that BoneCPnever spin-locks so it won't slow down your application.
官方主頁：

1.A database that accepts connections

2.A driver to go with it

3.Google Guava library, available for free from here.

4.The SLF4J logginglibrary.

5.JDK1.5 or higher.

即
bonecp-0.7.0.jar

google-collections-1.0.jar

package com.bonecp;
 
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
 

使用DataSource

package com.bonecp;

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import com.jolbox.bonecp.BoneCPDataSource;

publicclass ExampleDataSource {
    
    publicstaticvoid main(String[] args) {
        
        Connection connection =null;
        
        try {
            Class.forName("com.mysql.jdbc.Driver");
        } catch (Exception e) {
            e.printStackTrace();
        }
        
        BoneCPDataSource dataSource=new BoneCPDataSource();
        dataSource.setUsername("root");
        dataSource.setPassword("root");
        dataSource.setJdbcUrl("jdbc:mysql://localhost:3306/demo");
        dataSource.setMaxConnectionsPerPartition(10);
        dataSource.setMinConnectionsPerPartition(5);
        dataSource.setIdleConnectionTestPeriod(60);
        dataSource.setIdleMaxAge(240);
        dataSource.setAcquireIncrement(5);
        dataSource.setReleaseHelperThreads(3);
        try {
            connection=dataSource.getConnection();
            if (connection !=null){
                System.out.println("Connection successful!");
                Statement stmt = connection.createStatement();
                ResultSet rs = stmt.executeQuery(" select * from person "); // do something with the connection.while(rs.next()){
                    System.out.println(rs.getString(1)); // should print out "1"'                    System.out.println(rs.getString(2)); // should print out "1"'                }
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }finally{
            try {
                connection.close();
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
        
        
    }
    
}

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：

1. <!-- Hibernate SessionFactory -->
2. <beanid="sessionFactory"class="org.springframework.orm.hibernate.LocalSessionFactoryBean"autowire="autodetect">
3. <propertyname="hibernateProperties">
4. <props>
5. <propkey="hibernate.connection.provider_class">com.jolbox.bonecp.provider.BoneCPConnectionProvider</prop>
6. <propkey="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>
7. <propkey="hibernate.connection.url">jdbc:mysql://127.0.0.1/yourdb</prop>
8. <propkey="hibernate.connection.username">root</prop>
9. <propkey="hibernate.connection.password">abcdefgh</prop>
10. <propkey="bonecp.idleMaxAge">240</prop>
11. <propkey="bonecp.idleConnectionTestPeriod">60</prop>
12. <propkey="bonecp.partitionCount">3</prop>
13. <propkey="bonecp.acquireIncrement">10</prop>
14. <propkey="bonecp.maxConnectionsPerPartition">60</prop>
15. <propkey="bonecp.minConnectionsPerPartition">20</prop>
16. <propkey="bonecp.statementsCacheSize">50</prop>
17. <propkey="bonecp.releaseHelperThreads">3</prop>
18. </props>
19. </property>
20. </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></bonecp-config>
