一些背景:
我在Tomcat 7上运行了一个Java 1.6 webapp.数据库是MySQL 5.5.以前,我使用Mysql JDBC驱动程序5.1.23连接到数据库.一切正常.我最近升级到Mysql JDBC驱动程序5.1.33.升级后,Tomcat会在启动应用程序时抛出此错误.
WARNING: Unexpected exception resolving reference
java.sql.SQLException: The server timezone value 'UTC' is unrecognized or represents more than one timezone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc timezone value if you want to utilize timezone support.
为什么会这样？
