com.mysql.jdbc.exceptions.jdbc4.CommunicationsException
出现这样的问题 怎么办啊
com.mysql.jdbc.exceptions. The driver was unable to create a connection due to an inability to establish the client portion of a socket.

This is usually caused by a limit on the number of sockets imposed by the operating system. This limit is usually configurable.

For Unix-based platforms, see the manual page for the 'ulimit' command. Kernel or system reconfiguration may also be required.
