之前工作过程中自定义的代码生成器模版,codesimit

动软代码生成器 和codesmith

5年前的东西，或许有些过时

动软的功能有限，改的也比较简单，已弃。

codesmith可定制性强，当时自已改的，提高了团队的整体工作效率。

codesmith代码定制时用C#开发，但代码生成器的应用并不限于语言

结构类似，架构清楚的数据结构，业务结构，架构规范，错误码，各语言都有

个人用过codesmith支持过 C# JAVA PYTHON GO NODEJS的代码生成。

比较奇怪的是，很多人看不起代码生成器的同时，却在用很低效的人工来构造重复代码……

java，C#基于传统数据库的同学对这些即使未定制过，也不会陌生，后期从事相关的node go hadoop restfull，爬虫，协议封装，大数据MR,都有能应用的场景，相关人员对此却很陌生。

虽然体现不了什么技术深度，但能提升开发效率，减少人工误差，也好腾出精力作更深入的事。

这东西只是一个高效的辅助工具，从来不是核心竟争力，不建议投入太多精力于此，基本够用即可（实际是5年写的都比较粗糙）

唯一比较头疼的是，codesmith只支持windows系统。

贴段代码直接放资源吧

语言C# 功能记不太清了，当时sqlserver集群很弱，成本太高，主要工作是作Nosql的迁移工作

1为减少大量sql带来的压力，用mongodb作非重的验证，同时保证一致性。

2把历史数据迁移至hive，重构统计模块，把基于sql的统计，改为基于MR的。

代码生成是用Mongo作验证为sql减压的部分。
