Embodiment 1

[0071] Step 1: The message sending device 11 receives the message body "Test" to be sent by the user and an attachment list containing three attachments. The file names of the three attachments are tree.jpg, river.bmp, and fit.exe;

[0072] Step 2: The message sending device 12 packs the message body "Test" into a message file named CM7Z7BYJ0001.dat; according to whether the attachment is in a compressed format, pack the attachment into the above message file respectively, and the extension of the attachment tree.jpg is "jpg" , in the preset compression format extension list, so determine tree.jpg as the compression format, set its compression flag to false, and directly pack it into a message file named CM7Z7BYJ0001.dat; the extension of river.bmp is "bmp", in the preset uncompressed format extension, sets its compression flag to true, compresses it, and packs it into a message file named CM7Z7BYJ0001.dat; for the "fit.exe" file, Since in reality, the file with the "exe" exte...

Abstract

The invention discloses a data packing and transmitting method and a data packing and transmitting system for message-oriented middleware and relates to the field of data communication. The method includes: firstly, packing message bodies and attachments to be sent into a message file by a messaging device, and during packing, enabling a file format recognition module to judge whether the packed attachments are in a compressed format or not, directly packing the attachments into the message file if yes, and otherwise, compressing the attachments prior to packing the attachments into the message file; then, sending the message file to a message receiving device through a data exchange server, and enabling the message receiving device to directly unpack according to compression markers of the attachments or unpack firstly and decompress to obtain the attachments, so that one-time message transmission process is completed. By the aid of the method and the system, compressed files and non-compressed files in a message attachment list can be handled differentially, and the files in the compressed format are packed directly without being compressed, so that resources of a CPU (central processing unit) are saved; and the files in a non-compressed format are compressed prior to being packed, so that data size transmitted on the network is reduced, and transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data packaging transmission method and system of message middleware. Background technique [0002] For data exchange, multiple files are usually compressed or directly packaged into an object file, and then exchanged via a removable storage device or via the Internet. When packaging multiple files, some of the files to be packaged are in compressed format, while the other part of the files are in non-compressed format, for compressed files such as JPG and GIF files, compress them when packaging The compression ratio is very limited, which will waste CPU resources; and for non-compressed files such as BMP files, if data exchange is performed without compression, a large amount of storage space or network bandwidth resources will be wasted. In the prior art, when multiple files are packaged into one target file, all files to be packaged are compressed, such as ZIP for...
