Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] figure 1 It shows a flow chart of a Web service composition method based on QoS index and Web service output parameters executed by a Web service composition device according to an embodiment of the present invention.

[0033] Such as figure 1 As shown, in step S110, specify a Web service composition template for Web service composition. The Web service composition template is an abstract definition of Web services in the Web service composition process. The Web service combination template includes multiple service templates, and each service template may include multiple candidate Web services.

[0034] After the specification of the Web service composition template is completed, the flow proceeds to step S120. In step S120, read the Web service composition rule from the storage unit of the Web service composition device, wherein the Web service compositio...

Abstract

The invention provides a Web service combined method based on QoS indexes and Web service output parameters. The method comprises the following steps: reading Web service combinational rule from a memory, wherein presetting the Web service combinational rule according to required QoS indexes and Web service output parameters; analyzing the read Web service combinational rule; selecting a group ofWeb service combination from candidate Web services; using a Web service combination engine to acquire the QoS indexes of each Web service in the selected Web service combination; acquiring the outputparameters of each Web service in the selected Web service combination on the basis of reflective technology; judging whether the acquired QoS indexes and / or Web service output parameters of each Webservice meet the Web service combinational rule or not to determine whether the selected Web service combination is the required Web service combination, wherein when the QoS indexes and Web serviceoutput parameters of each acquired Web service both meet the Web service combinational rule, determining the Web service combination to be the required Web service combination.

Description

technical field [0001] The invention relates to the field of network services, in particular to a method and device for combining Web services based on QoS indicators and output parameters of Web services. Background technique [0002] With the increasing maturity of Web service technology, more and more stable and easy-to-use Web sharing services appear on the Internet. However, due to the limited functions that a single Web service can provide, in order to make full use of shared Web services, it is necessary to integrate shared Web services to provide users with more powerful service functions and speed up system development. And quickly meet user needs. The integration of Web services is generally called Web service composition in the field. [0003] In the prior art, there are usually two Web service composition methods: a static Web service composition method and a fixed-rule Web service method. [0004] The static Web service composition method is a Web service com...
