jdbc线程池

连接oracle数据库的jdbc线程池

首先建立一个properties类型的文件存放一些信息：jdbc.properties

 driverClassName=oracle.jdbc.driver.OracleDriver
 url=jdbc\:oracle\:thin\:@localhost\:\:orcl
 username=teacher
 password=ok
 initialSize=
 maxActive=
 #maxIdle=
 #minIdle=
 maxWait=

此处建立一个工具类，专门为了建立连接，关闭连接，代码如下：

 package com.dao;

 import java.io.FileInputStream;
 import java.sql.Connection;
 import java.sql.SQLException;
 import java.util.Properties;

 import javax.sql.DataSource;

 import org.apache.commons.dbcp.BasicDataSourceFactory;

 public class JdbcUtil {
     private static DataSource ds;
     static{
         Properties p = new Properties();
         try {
                         //此处jdbc.properties文件使用的是绝对路径
             p.load(new FileInputStream("E:\\甲骨文软件\\eclipse-jee-kepler-SR2-win32-x86_64\\WebWorkspace\\ServletTest\\src\\jdbc.properties"));
             ds=BasicDataSourceFactory.createDataSource(p);
         } catch (Exception e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         }

     }
     public static Connection getConnection(){
         Connection conn=null;
         try {
             conn=ds.getConnection();
         } catch (SQLException e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         }
         return conn;
     }
     public static void CloseConnection (Connection conn){
         if(conn!=null){
             try {
                 conn.close();
             } catch (SQLException e) {
                 // TODO Auto-generated catch block
                 e.printStackTrace();
             }
         }
     }
 }
