这是我做毕业设计时写的一个代码框架生成器，因为我所设计的系统数据访问部分采用托管容器式持久性（Containet-Managed Persistence,CMP）方式，在这种设计模式下我们不必考虑数据从何处来，以何种方式存放，支持多数据库。所以在编码前，写了个代码生成器，减少体力劳动。-This is what I do design graduation wrote a code generator fr a mework. because I designed the system data used to visit some of the Trusteeship Council-lasting containers (Containet-Mana ged persistence, CMP), in this design model we need not consider the data from where, in what form, and multi-database support. So the coding ago, wrote a code generator, reducing manual.
