Java MYSQL连接在Windows 7中运行，适用于Mac

标签： java mysql hibernate jdbc

相同的程序在Mac上运行，但似乎不适用于Windows。 我尝试过使用hibernate和常规的mysql.connection，但两者似乎都挂了。

我的防火墙全部关闭，通过第三方程序（如sqlyog）甚至通过netbeans中的HQL查询生成器连接到数据库都没有问题。但是在编译时，连接到数据库似乎会挂起大约5分钟，然后打印出以下错误。

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure    
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

当我切割＆amp;将您的错误粘贴到Google中，然后将其带回this。如果您没有使用标准端口3306，请尝试使用它，看看是否可以改善这一点。

我切割＆amp;将您的错误粘贴到Google并重新获得此链接：

不知道它是否与您的情况相同。我建议将来练习。我会比等待6-8周的答案快得多。
