The latter is the emphasis of this article . its hard core is the accidence analysis builder grammar _ lexer . mll and the syntax analysis builder grammarjpaser . mly . it transforms the fortran character string in the program , which would be processed automatic differentiation transform , into data stream of diversified syntax units 词法分析和语法分析部分又分为输入命令数据流以及fortran源程序数据流的词法分析和语法分析，后一部分是本文分析的重点，它以词法分析程序生成器grammarlexer . mll和语法分析程序生成器grammarpaser . mly为核心，将进行自动微分变换的fortran源代码字符串变换成各类语法单位的数据流。
In this paper , how to evolve the action component part of struts framework into black - box framework using java reflection and program generator respectively is discussed , taking the adding , deleting , modifying in a database in struts + ejb - kiatabase three layers architecture as an example . i first present a white - box framework based implementaion that adding , deleting , modifying a database , then how to evolve the action component part of struts framework into black - box framework using java reflection and program generator respectively in the target domain is discussed , thereby all these operations can implement without programmingjust config in a xml file , reach the objective of reducing the duplicate codes , improving the maintainability , cutting down the cost of developing applications 首先给出了基于白盒struts框架的对数据库表的增、删、改操作的一个实现，然后分别采用反射机制和程序生成器技术将struts框架的action组件部分在这一目标领域里进化为黑盒框架，从而使所有对数据库的增、删、改不再需要编程，只需在xml文件中进行相应配置即可，达到减少重复代码的数量，提高程序的可维护性，降低开发成本的目的。
