推荐答案

毫无疑问，代码是正确的."这是极不可能的，因为许多其他人使用相同的连接器应用程序.这意味着您的问题实际上在您的代码中.
调试您的应用程序，并确保您没有隐藏任何引发的异常.检查并研究您返回的消息，您将发现错误.

"There is no doubt in code." This is highly unlikely as many others use the same connector application. That means that your issue is in fact in your code.
Debug your application and make sure you don''t hide any exceptions that are thrown. Examine and study the messages you get back and you will find the bug.

您的计算机是32位还是64位计算机?

is your machine a 32bit or 64bit machine?

MySQL包含内部用户数据库，请确保您仍然有权访问要尝试访问的任何数据库.另外，请确保您没有防火墙阻止访问.

MySQL contains an internal database of users, make sure you still have permission to access whatever database you''re trying to get to. Also, make sure you don''t have a firewall blocking access.
