加载驱动

static{
        try {
            Class.forName("com.mysql.jdbc.Driver");
            Class.forName("oracle.jdbc.OracleDriver");
            
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        //Class.forName("net.sourceforge.jtds.jdbc.Driver");  

    } 

引入驱动包
