H2建立JDBC连接和JDBC连接池

[注：jar包在下载的安装目录下]
1、JDBC连接

package com.boonya.h2.jdbc.connection;
import java.sql.Connection;
import java.sql.DriverManager;
/**
 * DBConnection.java
 * 功能:测试H2提供的JDBC连接
 * @author boonya
 * @version 1.0 2013-03-11
 */
public class DBConnection {
	   private static String url="jdbc:h2:~/test";
	   private static String driver="org.h2.Driver";
	   private static String username="sa";
	   private static String password="123456";
	
	   public static Connection getConnection(){
		   Connection conn=null;
		   try{
		       Class.forName(driver);
		       conn=DriverManager.getConnection(url,username,password);
		   }catch(Exception e){
		        System.out.println("DBConnection create connection is failed:");
		        e.printStackTrace();
		   }
		   return conn;
	   }
	   
	   public static void main(String[] args) {
		   System.out.println(DBConnection.getConnection());//打印:conn1: url=jdbc:h2:~/test user=SA
	   }

}

2、JBDC连接池

package com.boonya.h2.jdbc.conntion.pool;
import java.sql.Connection;
import java.sql.SQLException;
import org.h2.jdbcx.JdbcConnectionPool;
/**
 * DBConnectionPool.java
 * 功能:测试H2提供的JDBC连接池
 * @author boonya
 * @version 1.0 2013-03-11
 */
public class DBConnectionPool{
	
	private static JdbcConnectionPool pool=JdbcConnectionPool.create("jdbc:h2:~/test", "sa", "123456");
	
	static{
		pool.setLoginTimeout(10000);//建立连接超时时间
		pool.setMaxConnections(100);//建立连接最大个数
	}
	
	public static JdbcConnectionPool getJDBCConnectionPool(){
		return pool;
	}
	
	public static Connection getConnection(){
		try {
			return pool.getConnection();
		} catch (SQLException e) {
			System.out.println("DBConnectionPool create connection is failed:");
			e.printStackTrace();
		}finally{
			pool.dispose();        //释放空闲连接
		}
		return null;
	}
	
	public static void main(String[] args) {
		System.out.println("Timeout :"+DBConnectionPool.getJDBCConnectionPool().getLoginTimeout()+" ,connection count:"+DBConnectionPool.getJDBCConnectionPool().getMaxConnections());
		System.out.println(DBConnectionPool.getConnection());
	}

}
