Web service combination method

The invention discloses a Web service combination method and aims to solve the technical problem of low combination efficiency of the whole system due to masses of redundant operations of the existing Web service combination method. The technical scheme is that a hierarchical storage structure is adopted; according to the trace and analysis on a historic combination request procedure, a combination request which is used most probably in a next combination request and a Web service used by the combination request are respectively stored in two virtual storage units, i.e. a Web service request processing unit and a hot spot Web service unit, of a local combination server and are set to have a priority access right; and when a certain Web service combination request is responded to, the virtual storage units, i.e. the Web service request processing unit, the hot spot Web service and the like, and a local Web service set are accessed sequentially. The Web service combination method avoidsmasses of redundant opera
