Java自己动手写连接池四

测试：

package com.kama.cn;

import java.sql.Connection;

public class Test {

public static void main(String[] args) {

for(int i=0;i<100;i++)
{
ConnectionPool connectionPool=ConnectionPool.getInstance();

Connection conn=connectionPool.getConnection();

System.out.println(conn);
System.out.println("当前连接池的大小:"+ connectionPool.poolSize());

//释放连接
connectionPool.realseConnection(conn);
System.out.println("当前连接池的大小:"+ connectionPool.poolSize());
}
}
}
