Software development method and device based on service composition

The embodiment of the invention provides a software development method and device based on service composition, relates to the field of software development, and solves the problems that a lot of manual interventions are needed in a traditional software development method based on the service composition due to the absence of a unified standard in a whole software development process, so that a quick response cannot be made when the requirement changes and the efficiency is low. The specific scheme is as follows: acquiring service demand information of software to be developed and retrieving a matched target service scene template from a service scene template base; correcting the target service scene template according to the service demand information of the software to be developed, and obtaining the corrected service scene template; and combining an acquired composite service code used for combing the corrected service scene template and a service code used for describing each function description informa
