The invention relates to the technical field of Java server development, in particular to a diversified interface document generation method. The method comprises the following steps: firstly, addingat ApiDoc annotations to the head of a module Controller class; then at ApiOperiton is added to the interface entry method, then an interface address, a name, description, authority, an input parameter class, an output parameter class and a header head class are set, and when a final project is started, all the methods needing to generate the interface document can be automatically scanned, and the customized interface document is generated. According to the invention, the synchronization problem of the interface document along with the code is solved; Developers, testers and operation and maintenance personnel can understand interface documents automatically generated by the system more clearly and more accurately.
