JavaJDBC-使用数据库连接池技术（Druid）获取Connection对象

三、获取Connection对象

private static DataSource source;

    //静态代码块
    static {

        try {
            Properties pros=new Properties();
            InputStream is = ClassLoader.getSystemClassLoader().getResourceAsStream("druid.properties");
            pros.load(is);
            source=DruidDataSourceFactory.createDataSource(pros);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    //getConnection
    public static Connection getConnectionByDruid()throws Exception
    {

        Connection conn=source.getConnection();
        return conn;
    }
