Method, apparatus and system for processing composite service and replacing service and invoking service

摘要

The present invention relates to a method for handling and replacing a composite service. The method for handling a composite service may include obtaining a concrete service corresponding to a service invocation segment description in a composite service logic, wherein the service invocation segment is an abstract service invocation segment or a service template invocation segment; triggering a service replacement, requesting to replace the service invocation segment with a concrete service invocation segment of the obtained concrete service; or, triggering a service invocation, requesting to generate a service invocation based on the concrete service. The method for replacing a composite service may include acquiring service template information associated with concrete service invocation segment information in the composite service logic; replacing the concrete service invocation segment information in the composite service logic with the service template information. Apparatuses for handling and replacing a composite service are also disclosed according to the present invention. A system for composite service is further disclosed. Accordingly, a concrete service can be dynamically selected when the composite service logic is being executed.
