public Connection connectToMySql() \{

            Class.forName(driver).newInstance();//处理异常  
            Connection connection = DriverManager.getConnection(url,"root","填密码");//处理异常  
            System.out.println(connection.toString());//测试是否连接成功  
            return connection;  
        \} catch (Exception e) \{  
            e.printStackTrace();  
            System.out.println("error:数据库连接出错");  
        \}  
        return null;//catch之后执行  
    \}![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQwMDEzNjg1_size_16_color_FFFFFF_t_70 13][]
