开发环境：
Idea Maven Mysql版本 6.0.6
报错信息（以下所有的报错信息均只截取了重要部分）：

检查地点：
No.1–generatorConfig.properties配置文件
No.2–查看pom.xml Mysql包的引用是否正确
No.3–检查pom.xml build 打包配置
No.4 --检查引用 generatorConfig.xml 文件

如果你这三处都没问题就应该，不会报这个错了。
PS：去掉空格的前提下。
但是如果你跟我一样是mysql 6.0.6及以上版本 可能还会出现另外一个问题如下：

Column name pattern can not be NULL or empty？

我爱你

心有所念人

隔在远远乡

我所有的时间都有来思念你了

留不出一秒去怀疑

愿你看到我给的一切

都干净透明
