摘　　要：为了在JavaWeb开发中解析STEP文件,提出了EXPRESS语言到Java语言的一般映射方法。构建了EXPRESS到J ava映射的总体框架,设计了EXPRESS中的数据类型和表达式的映射方法及其具体实现,开发者可依据映射元素的类别选择对应的映射规则。最后,通过案例演示了文中提出的映射方法在映射过程中的具体实现。In order to parse STEP files in JavaWeb development, a general mapping method from EXPRESS language to Java language is proposed. The overall framework of EXPRESS to Java mapping is constructed, and the mapping method of data types and expressions in EXPRESS and its specific implementation are designed. Developers can choose the corresponding mapping rules according to the types of mapping elements. Finally, a case demonstrates the specific implementation of the proposed mapping method in the mapping process.
