在使用最新的mysql-connector-java 6.0.5时,获取表定义信息会抛出空指针异常:

解决办法:在mysql的连接串中指定参数nullCatalogMeansCurrent=true,
<property name="url"><![CDATA[jdbc:mysql://localhost:3306/bboss?serverTimezone=UTC&useSSL=false&nullCatalogMeansCurrent=true]]></property>
可能还需要指定时区serverTimezone参数否则也会报其他错误:这里指定为serverTimezone=UTC
