   我们默认用户在建表时会创建createTime、updateTime字段(忽略大小写、下划线命名风格)且默认值均为`CURRENT_TIMESTAMP`，而updateTime支持`ON UPDATE CURRENT_TIMESTAMP`，对于这两个字段生成`insert`、`update`时会被移除，不在赋值范畴内，当然，如果你不需要这两个字段那也无大碍。

   目前仅支持redis缓存，如果选择带缓存模式，即生成的`FindOne(ByXxx)`&`Delete`代码会生成带缓存逻辑的代码，目前仅支持单索引字段（除全文索引外），对于联合索引我们默认认为不需要带缓存，且不属于通用型代码，因此没有放在代码生成行列，如example中user表中的`id`、`name`、`mobile`字段均属于单字段索引。
