JDBC连接步骤

        Class.forName("com.mysql.jdbc.Driver");//设置驱动
        Connection con = DriverManager.getConnection(
                "jdbc:mysql://10.0.0.207:3306/db_boss", "root", "123456");//获取连接
        Statement state = con.createStatement();//创建Statement
        ResultSet result = state.executeQuery("select * from CHANNEL");//执行SQL
        while (result.next())
        {
            System.out.print(result.getInt(1) + "--" + result.getString(5)//
                    + "\n");//处理结果集
        }
