休眠mysql的问题

有两件事情我想从hibernate.cfg.xml中做mysql数据库;休眠mysql的问题

要有utf8的字符，以便它可以攒人品C，C，Z，DJ，S和repoduse他们作为大公都不如？在Tapestry应用。
修复的com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException

No operations allowed after connection closed.Connection was implicitly closed due to underlying exception/error: ** BEGIN NESTED EXCEPTION ** com.mysql.jdbc.exceptions.jdbc4.CommunicationsException MESSAGE: The last packet successfully received from the server was48709 milliseconds ago.The last packet sent successfully to the server was 48709 milliseconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

我hibermate.cfg.xml

<?xml version="1.0" encoding="UTF-8"?>

    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

好，在你的CFG文件C，C，Z，DJ，的人物需要设置字符集设置为UTF-8也：

default-character-set=utf8

或这样的事情，......，我不是很喜欢这个休眠的东西，但我知道，你需要做到这一点。 “的charset = UTF-8”

也增加服务器超时旁边的命令：

set @@global.wait_timeout=31536000 
set @@session.wait_timeout=31536000
