二次开发

如果这些生成规则无法满足你的私人定制，那么欢迎对其进行二次开发，可联系我，然后我给你提供代码分支

本项目是基于 velocity 上开发的

项目架构

其中 该项目的核心类是 moduleHouse ，其中包括所有的配置文件信息，和数据库信息

模块的配置与扩展

一个module即对应一个类型的生成文件，如果需要生成属于自己的模板文件，请在modules中配置模块名称，然后再下文配置模块的详细信息

包括模板位置，并再 srcmainjavacomswingskywebgeneratorconstantModuleConstants.java 中新增该模块的常量表示

然后在 VelocityContextBuilder 中配置该模板文件生成时需要的上下文 VelocityContext 即可

扩展 so easy!
