Description
Technical field
The present invention relates to the broadcasting and TV field, particularly a kind of matchmaker supports the solution of metadata read and write access conflict.
Background technology
In the media asset management system of existing broadcasting and TV field TV station, the mode that reads that the matchmaker supports metadata is: total system is divided into a plurality of submodules, and each sub-module is accomplished the read-write to metadata through direct access system.Because each sub-module is distributed in the different server apparatus, and run on separately under the independent virtual machines environment.Therefore; When a plurality of modules are visited same file simultaneously, when particularly simultaneously in identical file, writing data, just be easy to each other clash; Prior art is difficult to this mutual conflict is managed, and writes, reads problems such as information is unusual with regard to having caused data to cover like this.
Summary of the invention
The present invention provides a kind of matchmaker to support the solution of metadata read and write access conflict.Mode through external issue Web Service interface provides service, has solved in the prior art because the data message that each server is produced when visiting same file simultaneously covers writes, and reads problems such as information is unusual.
For achieving the above object, one aspect of the present invention provides a kind of matchmaker to support the solution of metadata read and write access conflict, comprising:
Design a Web Service interface with synchronous obstruction latency function;
Carry out the synchronous flow process of interface;
Show saving result.
The present invention has the following advantages: the accessing operation through to metadata carries out the mode in the abstract set, and " data access service " of special provides service with the external mode of issuing Web Service interface.Other application program is if the accesses meta-data file must pass through this interface realization.So just the access logic with file is retracted in the controlled scope, lays the first stone for further realizing visit mutual exclusion logics such as thread lock, thread synchronization.In addition, the present invention is to the realization of thread synchronization, reached when server simultaneously accesses meta-data the time, and metadata is read, and revises the order of preservation and integrality.

Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
As shown in Figure 2, the solution for a kind of matchmaker of the embodiment of the invention supports metadata read and write access conflict comprises:
Step S201 designs a Web Service interface with synchronous obstruction latency function.
" data access service " of special provides service with the external mode of issuing Web Sercice interface.When if the accesses meta-data file is thought in other application programs or service, must realize through the interface of this service.This metadata access interface is divided into coarseness and fine granularity two big classes.Coarseness is in order to accomplish the integral body read-write of file; Fine granularity is in order to accomplish the part read-write of file.Two different interface classification adapt to the metadata access demand in different procedure links.Simultaneously, this interface is provided with the function design that synchronous obstruction is waited for.The function of interface each several part is as shown in table 1.
Step S202 carries out the synchronous flow process of interface.
At first, be divided into several portions to a metadata, for example: A section, B section, C section, D section, E section.
Secondly, the user can make amendment to the different portions of this metadata respectively and preserve operation.
Be specially, user 1 reads whole metadata, and the B section has been carried out the operation of revising and preserving, and simultaneously, user 2 also reads whole metadata, and the C section has been carried out the operation of revising and preserving.
As shown in Figure 2; User 1 and user 2 have carried out revising the preservation operation to metadata simultaneously; The content of its preservation belongs to different portions in the file, and, because this interface has the function that synchronous obstruction is waited for; Therefore B section and the C section in the file all obtained renewal after the synchronous processing, and the situation that file is lost or is capped do not occur.
Otherwise, if the design that does not have the synchronous obstruction of interface to wait for, the situation that the file after then preserving will cause confusion, the B section that user 1 revised is not preserved probably.
Step S203 shows saving result.
In fact, the key of synchronous processing is to be designed to the process that can not interrupt, can not bother with reading, change, deposit these a series of continuous processes, and therefore, the synchronous flow process mode of same interface also can reach the purpose of the different metadata of synchronous modification.
Need to prove that the synchronous flow process of this interface only is used for the read/write conflict of the different piece of Uncrossed meta data file in logic to be handled, if user 1 is the B section with the content that user 2 revises, then the B section content revised of user 1 can be capped.Therefore, above-mentioned situation the design does not consider to handle.
The embodiment of the invention is through designing a Web Service interface with synchronous obstruction latency function; Carry out the synchronous flow process of interface; So just the access logic with file is retracted in the controlled scope, lays the first stone for further realizing visit mutual exclusion logics such as thread lock, thread synchronization.
Through the description of above embodiment, those skilled in the art can be well understood to the present invention and can realize through hardware, also can realize by the mode that software adds necessary general hardware platform.Based on such understanding; Technical scheme of the present invention can be come out with the embodied of software product, this software product can be stored in a non-volatile memory medium (can be CD-ROM, USB flash disk; Portable hard drive etc.) in; Comprise some instructions with so that computer equipment (can be personal computer, server, the perhaps network equipment etc.) carry out the described method of each embodiment of the present invention.
It will be appreciated by those skilled in the art that accompanying drawing is the synoptic diagram of a preferred embodiment, module in the accompanying drawing or flow process might not be that embodiment of the present invention is necessary.
The invention described above embodiment sequence number is not represented the quality of embodiment just to description.
More than disclosedly be merely specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
