自己寫的一個數據庫連接池的使用

1.在工程裏面加入以下jar文件：

    mydatasource.jar，--

     dom4j.jar,

     ojdbc

 2.把連接池配置文件放在工程src目錄下或者其他目錄，如pool.xml,其內容如下：

  <?xml version="1.0" encoding="UTF-8" ?>

<pools>
        <pool name="default">
           <driver-class>
                oracle.jdbc.driver.OracleDriver
           </driver-class>
           <url>jdbc:oracle:thin:@192.168.1.7:1521:TESTDB</url>
          <username>appuser</username>
          <password>111111</password>
           <maxPoolSize>1</maxPoolSize>
      </pool>
      <pool name="db2">
          <driver-class>
              oracle.jdbc.driver.OracleDriver
          </driver-class>
         <url>jdbc:oracle:thin:@192.168.1.151:1521:myDB</url>
        <username>admin</username>
        <password>admin</password>
       <maxPoolSize>1</maxPoolSize>
       </pool>
 </pools>

3。測試類

import java.sql.ResultSet;
import java.sql.Statement;

import org.sky.datasource.ConnectionPoolFactory;
import org.sky.datasource.IConnection;
import org.sky.datasource.IConnectionPool;

public class DsTest
{

    /**
     * @param args
     */
    public static void main(String[] args)
    {
        String conf = "/pool.xml";
        try
        {
            IConnectionPool pool = ConnectionPoolFactory.buildConnectionPoolFactory(conf).getConnectionPool("default");
            IConnection conn = pool.getConnection();
            Statement st = conn.createStatement();
            ResultSet rs = st.executeQuery("select *  from TB_EVENTS");
            while(rs.next()){
                System.out.println(rs.getString(1));
            }
            conn.close();
            //pool.realseConnection(conn);
                   }
        catch (Exception e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
       
    }

}
