Business logic coding framework generation method and system based on large language model

The invention relates to the technical field of software design and development, in particular to a business logic coding framework generation method and system based on a large language model. The method comprises the following steps: acquiring a design document; performing business entity identification on the design document to generate business entity data; performing inter-entity dependency relationship analysis on the service entity data to obtain entity dependency relationship data; performing flow sequence construction on the design document based on the entity dependency relationship data, and constructing a business flow chart; performing business logic analysis on the design document to generate business logic data; performing data mapping on the business flow chart by utilizing the business logic data, and constructing a business logic specification library; performing function module marking on the design document to obtain business function module data; and performing module calling analysis on
