试试这个

con = (Connection) DriverManager.getConnection("jdbc:mysql://bondsolutionsnjcom.fatcowmysql.csom:3306/account_information", "aiforfrg", "****");

试试这个

con = (Connection) DriverManager.getConnection("jdbc:mysql://bondsolutionsnjcom.fatcowmysql.csom:3306/account_information", "aiforfrg", "****");

试试这个

"jdbc:mysql://bondsolutionsnjcom.fatcowmysql.csom:3306/account_information"

而不是这个

"jdbc:mysql://bondsolutionsnjcom.fatcowmysql.csom:3306;account_information"

试试这个

"jdbc:mysql://bondsolutionsnjcom.fatcowmysql.csom:3306/account_information"

而不是这个

"jdbc:mysql://bondsolutionsnjcom.fatcowmysql.csom:3306;account_information"

服务器的URL有问题。。。它应该像下面这样 jdbc：mysql://localhost:3306/db_name

如果您使用的是远程服务器，您可以将“localhost”替换为首选服务器名称，并且端口号应该相应地更改。

感谢您的响应，不过我现在有一个新错误。请参阅编辑后的post.EDIT：我尝试ping链接bondsolutionsnjcom.fatcowmysql.csom，作为回复，我收到了请求超时。您确定主机地址正确吗？请检查这些链接：[link][link]是的，我在我的php文件中使用了相同的代码。然而，我确实注意到，出于某种原因，我有csom。虽然即使更改为com，它也有相同的错误。您是否可以尝试在命令提示符/终端上使用以下命令：ping bondsolutionsnjcom.fatcowmysql.csom或ping 202.136.40.61 IP地址，当我在我的终端上使用ping命令时，检查您得到了什么？请求超时。但是，我的php文件仍然可以正常工作。感谢您的回复，我现在有一个新的错误。请参阅编辑后的post.EDIT：我尝试ping链接bondsolutionsnjcom.fatcowmysql.csom，作为回复，我收到了请求超时。您确定主机地址正确吗？请检查这些链接：[link][link]是的，我在我的php文件中使用了相同的代码。然而，我确实注意到，出于某种原因，我有csom。虽然即使更改为com，它也有相同的错误。您是否可以尝试在命令提示符/终端上使用以下命令：ping bondsolutionsnjcom.fatcowmysql.csom或ping 202.136.40.61 IP地址，当我在我的终端上使用ping命令时，检查您得到了什么？请求超时。但是，我的php文件仍然可以正常工作。感谢您的回复，我现在有一个新的错误。请参阅编辑后的文章。我确实这样做了，但我发现，问题是我的db主机不允许JavaJDBC连接。我想到的java php桥接器有什么解决方法吗？您现在遇到的异常是什么？仍然不知道hostexception或任何其他异常？这是一个处理jdbc的驱动程序异常。我试过多次修改我的代码，我不确定tpo是否会产生错误。但是新的错误基本上意味着我的db服务器拒绝了jdbc请求。看起来我唯一的选择是php和perl。你能用当前得到的异常更新你的问题吗？谢谢你的回答，不过我现在有一个新的错误。请参阅编辑后的文章。我确实这样做了，但我发现，问题是我的db主机不允许JavaJDBC连接。我想到的java php桥接器有什么解决方法吗？您现在遇到的异常是什么？仍然不知道hostexception或任何其他异常？这是一个处理jdbc的驱动程序异常。我试过多次修改我的代码，我不确定tpo是否会产生错误。但是新的错误基本上意味着我的db服务器拒绝了jdbc请求。看起来我唯一的选择是php和perl。你能用当前得到的异常更新你的问题吗？
