Software project document generating method and software project document generator

The invention provides a software project document generating method and a software project document generator. The method comprises the following steps of acquiring identification information of an atomic object in a project object which is required to be generated; seeking a project document library which is matched with the identification information of the atomic object; copying contents of atomic document contents in the matched project document library; and adhering the copied atomic document contents to corresponding positions of an acquired project document template. By the software project document generating method and the software project document generator, a software project document can be generated automatically, the document contents of the existing software project can be effectively reused or inherited, human errors can be avoided, and the software development efficiency is improved.
