Cannot create PoolableConnectionFactory

在tomcat的server.xml中的<Resource>里配置数据库连接，分了三行，但是启动总是报下面的错误，很是郁闷，后来将这三行整理成一行，启动tomcat居然成功了，整理一下，如果有遇到类似情况的伙伴，可以使用这种方式试一下。

报错代码：

Cannot create PoolableConnectionFactory (The connection property 'zeroDateTimeBehavior' only accepts values of the form: 'exception', 'round' or 'convertToNull'. The value 'conv ertToNull' is not in this set.)
