Electronic invoices are used more and more widely as important electronic certificates in life and work, and are gradually popularized and standardized. The format of an electronic invoice file is formally standardized to be OFD on a public platform of a value-added tax electronic invoice of the State tax administration in 2019, that is, the electronic invoice in the OFD format appears in the life of each person, so that the OFD electronic invoice generated by a large number of transactions generated every moment becomes an important problem concerned by an electronic invoice platform. A typical OFD electronic invoice generation process is shown in fig. 1.
1. Firstly, the manufactured electronic invoice template is imported into a background.
2. And the background decompresses and analyzes the electronic invoice template.
3. And the background receives the invoicing data of the foreground, imports the invoicing data into the decompressed electronic invoice template, and compresses the invoicing data to generate the OFD electronic invoice.
4. And the background transmits the OFD electronic invoice file into an electronic signature system.
5. The electronic signature system decompresses, analyzes, signs and compresses the OFD file to generate the OFD electronic invoice file with the signature.

As shown in fig. 1, one embodiment of the present application provides an electronic invoice generation system, including an invoice mold management platform, an invoice pool platform, and an invoice generation platform.
The invoice mould management platform is used for managing invoice moulds, can manage and store various OFD invoice moulds, and mainly comprises the following functions: adding and deleting the mold, optimizing the mold, managing the background, backing up and the like. The optimization of the die mainly comprises the step of optimizing the size of the die; the background management mainly carries out daily maintenance and management work on the die; the backup mainly carries out backup on the invoice mould; the invoice mould manufacturing foreground can design a new invoice mould and upload the invoice mould to the invoice mould management platform.
The invoice mould comprises an OFD invoice mould. The OFD invoice mold is different from a common invoice mold which is a common OFD file, but the invoice mold is an uncompressed OFD file package, and because the compression is not performed, one decompression process is omitted in the invoice generation process, so that the generation efficiency can be improved. The OFD invoice mould mainly consists of several files: xml, document xml, publicres xml, content xml, tags xml, annots xml, and attachs xml, as shown in fig. 3:
1) xml is an entry file of the OFD file, including metadata, version number, and path of doument.
2) Xml is a document entry of an OFD file, and includes paths of a public resource file public res.xml, a page content file content.xml, and the like, and the path of the resource file and the page content file can be obtained by analyzing the file, and further, the content of the resource file and the content of the page file can be obtained.
3) Xml is a common resource entry file for OFD files, and is used to store paths for pictures and font files, including two-dimensional code picture paths for invoices.
4) Xml is a page file of the OFD file, and is used to store data of the page, and additionally, the invoicing data is imported into content.xml;
5) xml is a semantic entry file of the OFD file for storing a path of the invoice semantic file, such as the path of tag.
6) Xml is the annotation entry of the OFD file for storing the path of the document annotation file, such as the path of Annot _0. xml.
7) Xml is an attachment entry of the OFD file for storing a path of a document attachment file, such as the path of Attach _0. xml.
The OFD electronic invoice mould file package is generally within 5K, and the occupied space is very small, so the OFD electronic invoice mould file package is directly stored in a database without compression for reducing the compression and decompression times.
The invoice pool platform is used for acquiring a corresponding invoice mould from the invoice mould management platform according to invoice information to be issued by a client, caching all invoice mould file packages, and supporting functions of importing, inquiring, deleting, backing up and the like. The background is a distributed memory database, supports a master-slave cluster, can achieve high concurrency and has high availability.
The invoice pool platform is used for conveying invoice information to be issued by a client and corresponding invoice moulds to the invoice generation platform when an invoice issuing request exists, and conveying the corresponding invoice moulds to the invoice generation platform according to the invoice information (such as invoice types and the like) issued by the client.
The invoice generation platform is used for combining the invoice die with invoice information to generate an electronic invoice and carrying out signature.
The invoice mould management platform adopts a database for storage, is easy to maintain and manage, has a backup function, can perform operations such as increasing, deleting, modifying, checking and the like on the mould in real time, and can manage a large number of invoice moulds simultaneously.
The invoice pool platform adopts the NOSQL memory database, so that the query speed can be increased, the load capacity of the whole device is improved, if the invoice pool platform is not provided, the invoice generation platform is directly interacted with the invoice mold management platform, the invoice mold management platform needs to be frequently connected with the database, and because the invoice mold management platform adopts the relational database, the performance of the relational database is inferior to that of the memory database, the system overhead can be increased, and the query efficiency is reduced.
The system of the embodiment can be matched with a user service system and an invoice mould manufacturing foreground for use.
The electronic invoice generating system of the embodiment of the application is a real-time invoicing device integrating invoice mold management, invoice pool management and invoice generation, realizes high concurrency and high availability by carrying out pooling treatment on invoice molds and adopting memory distributed storage, and solves the problems of difficult invoicing of electronic invoices caused by queuing and the like.
