Embodiment
To a preferred embodiment of the present invention will be described in detail, in description process, having omitted is unnecessary details and function for the present invention with reference to the accompanying drawings, to prevent that the understanding of the present invention from causing, obscures.
Fig. 1 shows according to one embodiment of present invention the block diagram for the file management system 10 of mobile device file.As shown in Figure 1, file management system 10 comprises front end management unit 110, file change server 120 and document management server 130.Below, each assembly of the file management system 10 shown in Fig. 1 is described in detail.
Front end management unit 110 is to file server upload file, and by the relevant information recording of the file with uploading in database.In one example, the information relevant with the file of uploading can comprise document number, file address and file status.In addition, front end management unit 110 can also send to file change server 120 message that indication file has been uploaded after upload file, and described message can comprise document number and file address.
In addition, if the file transition status that described message comprises indication file convert failed, document management server 130 can also send message to file change server 120, with circular document change server 120, re-starts conversion.
In addition, document management server 130 can send by message push service the notice of upload file to mobile device.
In the present embodiment, above-mentioned each message can encapsulate with Json protocol format, and encodes with UTF-8 form.The file of uploading can comprise at least one in text, image file, web page files.File after conversion for example can comprise pdf document and jpeg file.
Below, in conjunction with the example shown in Fig. 3, describe the operation of each assembly of file management system 10 in detail.It should be noted that, although example is below carried out encapsulation messages and carrys out coded message with UTF-8 form with Json protocol format, and the file after conversion is pdf document and jpeg file, it will be appreciated by those skilled in the art that, message in the present invention can encapsulate and encode with any other applicable forms with any other applicable agreement, and the file after conversion can be other files of wishing type.
Fig. 3 shows the schematic diagram of the file management system for mobile device file according to an embodiment of the invention.As shown in Figure 3, keeper can utilize the upload file of front end management unit, for example, by File Transfer Protocol upload file.Particularly, keeper selects file that this locality need to upload (file format for example can comprise doc, docx, xls, xlsx, ppt, pptx, txt, pdf, csv, htm, html, jpg, jpeg, tif, tiff, bmp, png, gif), file is uploaded to file server.If upload failure, can point out mistake.If uploaded successfully, create document number (FileID), create upload file at the full address (FileURL) of file server, file status (FileStatus) is set for uploading.Then, front end management unit is recorded to FileID, FileURL and FileStatus in the t_file table of database (t_file list structure comprises field FileID, FileURL, PDFFileURL, JPGFileURL, FileStatus).Then, front end management unit can send type of message for the message of " uploading " is to message queue (ActiveMQ), circular document change server 120 files are uploaded, the content of this message comprises FileID and FileURL, and encapsulates and encode by UTF-8 coded format with Json protocol format.
The 120 monitoring message queues of file change server.When receiving that type of message is the message of " uploading ", file change server 120 is used Json protocol analysis message content, obtains FileID and FileURL.Then, file change server 120 is set up FTP communication with file server, uses FileURL that original is downloaded to this locality, and after downloading successfully, initiates PDF conversion, original is converted to pdf document and is stored in this locality.After changing successfully, file change server 120 is converted to the homepage of pdf document jpeg file and is stored in this locality.After this, file change server 120 uploads to original place catalogue in file server by pdf document and jpeg file.The title of pdf document and jpeg file can be used old file name to add PDF/JPEG suffix.
After uploading successfully, file change server 120 is deleted local temporary files and is sent message that type of message is " converting " to message queue, and circular document management server 130 files convert.The content of this message can comprise filename, file address and file transition status (FileConvertStatus) and return information (Message).If whole document converting process success, can arrange FileConvertStatus for conversion success status, Message fills in " success "; Otherwise it is convert failed state that FileConvertStatus can be set, Message fills in failure cause.This message can encapsulate with Json protocol format, and encodes by UTF-8 coded format.
Like this, when receiving the message that message cloud sends, mobile terminal is used Json protocol analysis message content, obtains filename.Then, mobile terminal can be set up Https communication to send request with document management server.Document management server receives this request, uses the table t_file of filename accessing database, obtains file address (FileURL), pdf document address (PDFFileURL) and jpeg file address (JPGFileURL), is returned to mobile terminal.Like this, mobile terminal can be set up Https communication by Nginx and file server, uses file address to download original, uses pdf document address to download pdf document, and uses jpeg file address to download jpeg file (preview graph).
Adopt the present embodiment, can realize unified management and the conversion to multiple file format for mobile device file, these conversions can be in the concurrent execution of background server, thereby has improved the efficiency of file conversion.
Fig. 2 shows according to one embodiment of present invention the flow chart for the file management method 20 of mobile device file.As shown in Figure 2, method 20 starts at step S210 place.
At step S220 place, to file server upload file, and by the relevant information recording of the file with uploading in database.For example, the file of uploading can comprise at least one in text, image file, web page files, and the information relevant with the file of uploading can comprise document number, file address and file status.
At step S230 place, from file server, obtain the file of uploading, the file obtaining is carried out to format conversion, and upload the file after conversion to file server.For example, the file after conversion can comprise pdf document and jpeg file.Alternatively, if file convert failed can re-start conversion.
At step S240 place, change the information relevant with file that upload that store in database, and to mobile device, send the notice of upload file.For example, can to mobile device, send by message push service the notice of upload file.
Finally, method 20 finishes at step S250 place.
