[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] The present invention is described below in conjunction with preferred implementation steps. Figure 1 is a flow chart of a data conversion method provided according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0026] Step S101, reading target data in a target format, and storing the read target data in a cached encryption object;

[0027] Step S102, parsing the target data in the encrypted object to obtain the header data and table data of the target data;

[0028] Step S103, creating a configuration class for the conversion format, and generating format data for the conversion format according to the configuration class;

[0029] Step S104, generating conversion data of a conversion format according to the class library, the header data, the table data, and the format data.

[0030] Through the above steps, the target data in the target format is read, and the read target data is stored in the cached encrypted object; the target data in the encrypted object is parsed to obtain the header data and table data of the target data; a configuration class of the conversion format is created, and the format data of the conversion format is generated according to the configuration class; the conversion data of the conversion format is generated according to the class library, the header data, the table data, and the format data, which solves the problem that in the business system of the related technology, when the report in HTML format is generated in batches in PDF format, more application server resources will be consumed, and there is a problem of low efficiency. Thus, the effect of quickly and efficiently generating the conversion format PDF according to the target format HTML batches is achieved.

[0031] The execution subject of the above steps can be a conversion tool, which can be an application program implemented by a program, and its corresponding hardware device can be set on a calculator, controller, server, etc. with computing power.

[0032] The step of reading the target data in the target format and storing the read target data in the cached encryption object can be performed by a buffered reading class to read the target data in the target format and store the read target data in the cached encryption object. The buffered reading class can be a buffered reading BufferedReader class. The target format can be a hypertext markup language HTML format, and the target data can be HTML data. The encryption object can be an encrypted file FileAndEnc object.

[0033] The above-mentioned step of parsing the target data in the encrypted object to obtain the header data and table data of the target data can be performed by parsing the target data in the encrypted object through a parsing library to obtain the header data and table data of the target data. The above-mentioned parsing library can be a hypertext markup language HTML parsing HTMLparser library, that is, a target format parsing library. The HTMLparser library is used to parse the hypertext markup language HTML data in the encrypted file FileAndEnc object to obtain the header data and table data respectively.

[0034] The above configuration class for creating the conversion format is used to generate the format data of the conversion format according to the configuration class. The format data of the generated portable document format PDF can be set by creating a new PDFConfiguration portable document format configuration class. As shown in Figure 2, the format data of PDF includes PDF page size, fixed header settings, page number settings, table alignment, table column width settings, text alignment, font settings, text line break settings, etc.

[0035] The above class library can be an itext library. According to the class library, header data, table data, and format data, conversion data of the conversion format is generated. The Document file class in the itext library can be used to add the content of the Table object. Finally, the PdfWriter class is used to write all the content added to the Document class into the output stream associated with the PDF file, and finally a PDF report is generated.

[0036] This solves the problem in the business system of the related art that when batch-generating reports in HTML format into PDF format, more application server resources are consumed, resulting in low efficiency. This achieves the effect of quickly and efficiently batch-generating converted PDF format according to the target format HTML.

[0037] Optionally, after creating a configuration class for the conversion format and generating format data for the conversion format according to the configuration class, the method further includes: storing the header data, the table data, and the format data in a table object of the target data.

[0038] The table object can be a table object, which stores header data, table data, and format data in the table object, and then adds the content of the table object, including header data and table data, through the file class of the class library, and generates PDF data according to the PDF format data. The header data, table data, and format data are stored in the table object of the target data. When the configuration class for generating PDF needs to obtain the data, it is directly obtained from the table object. On the one hand, it avoids the problem of obtaining header data, table data, and format data from different locations, which is prone to errors. Another invention also improves the efficiency of data acquisition.

[0039] Optionally, generating conversion data of a conversion format based on the class library, header data, table data, and format data includes: calling a file class through the class library to add data content of a table object; adding the file class to an output stream of the conversion format through a writing class of the conversion format to generate conversion data.

[0040] The above-mentioned file class can be the document configuration class in the itext text class library. The above-mentioned writing class can be the PDFwriterPDF writing class. The Document configuration file class in the itext text class library is used to add the content of the Table table object, and finally the PdfWriter class is used to write all the content added to the Document class into the output stream associated with the PDF file, and finally a PDF report is generated. The configuration class of the above-mentioned class library can directly obtain the header data, table data and format data required for data conversion from the above-mentioned table object, and then write the above-mentioned header data and table data into the data stream of the conversion format according to the format corresponding to the format data through the writing class to generate conversion data, thereby automatically generating corresponding conversion data according to the data stored in the table object, without the need for human intervention, thereby improving accuracy and conversion efficiency.

[0041] Optionally, adding data content of a table object by calling a file class through a class library includes: generating a preset format object according to header data and format data of the table object; and filling the table data in the table object into the preset format object.

[0042] As shown in Table 1, when PDF is generated, by parsing the table function parserTableToPdf(), the data of the table object can be output to the PDF object to obtain the above-mentioned preset format object, including PDF fixed header settings and repeated header settings for tables exceeding one page. Then fill the table data into the cells in the preset format object. Thus, according to the conversion format and the header data, blank conversion data with a table is generated, and then the table data is filled into the conversion data, and the data content of the target format is filled into the conversion data, so as to generate the conversion data quickly and effectively.

[0043] Optionally, filling the table data in the table object into the preset format object includes: paging the preset format object; for the non-first page of the preset format object, obtaining the fixed header of the first page according to the first requirement, and copying it to the non-first page, wherein the first requirement is used to indicate the header format of the non-first page.

[0044] The paging of preset format objects can be set according to the format data of the conversion data, such as the page size, and the content area of ​​each page can be determined. After the area is filled, the paging is automatically performed. The above-mentioned first requirement can be the user's requirement on whether a fixed header is displayed on the non-home page. After obtaining the fixed header, it is determined whether to display the fixed header according to the first requirement. In this way, the header format of the non-home page can be quickly and automatically generated according to the requirement on whether the header needs to be displayed on the non-home page. While automatically and quickly generating the conversion data, data conversion and conversion data generation are performed according to the header requirements to meet the user's different format requirements for the conversion data.

[0045] Optionally, generating a preset format object based on the header data and format data of the table object includes: creating a preset format object; inputting the header data into the preset format object; obtaining the format data of the preset format object according to a second requirement; and generating a table including a header in the preset format object based on the format data and the header data.

[0046] The second requirement may be whether to include a header, or whether to display the header in a preset format object. As shown in Table 1, an empty PDFptable table (including a header) can be obtained by using the getEmptyPdfPTable() function to obtain an empty table, so as to obtain the format data of a PDF object (preset format object) including a header. An empty PDFptable table (excluding a header) can be obtained by using the getEmptyPdfPTableNoHeader() function to obtain a non-header empty table, so as to obtain the format data of a PDF object (preset format object) not including a header. Data conversion and conversion data generation are performed according to the header requirements of the table in PDF to meet the different format requirements of users for the table of converted data.

[0047] Optionally, filling the table data in the table object into the preset format object includes: obtaining the table format of the table to be edited; and writing the table data corresponding to the table into the table according to the table format.

[0048] As shown in Table 1, by getting the cell function getPdfCell() method, you can get PDFCell, which is the format of the PDF cell, including text alignment, font settings (font size, bold, underline, superscript, subscript, etc.), text line break settings, and PDF page number replacement. When writing to a cell with a fixed format, write data according to its format. According to the format of the specific cell of the PDF table, write the cell data in the corresponding format, adjust the format of the cell data as required, or retain the cell format in the HTML table, so as to more completely restore the format of the table before conversion, and ensure the integrity of the table data content during the data conversion process as much as possible, or set the cell format according to the requirements to meet the user's requirements for setting the cell format.

[0049] Optionally, after generating conversion data of a conversion format according to the class library, header data, table data, and format data, the method further includes: compressing and packaging a preset number of generated conversion data to generate a conversion data packet, wherein the name of the conversion data packet includes a compressed package name and a serial number.

[0050] Since the number of HTML data is large and the data volume is small, the number of PDFs generated in batches is large and difficult to store. The generated preset number of conversion data is compressed and packaged to generate conversion data packets. For example, a large PDF named with zip package name_serial number will be generated for every 5000 PDFs. The generated PDFs are packaged for easy storage and subsequent search.

[0051] The data conversion method provided by the embodiment of the present application reads the target data in the target format and stores the read target data in the cached encrypted object; parses the target data in the encrypted object to obtain the header data and table data of the target data; creates a configuration class of the conversion format, and generates the format data of the conversion format according to the configuration class; generates the conversion data of the conversion format according to the class library, the header data, the table data, and the format data, which solves the problem that in the business system of the related technology, when the report in HTML format is generated in batches in PDF format, more application server resources will be consumed, and there is a problem of low efficiency. Thus, the effect of quickly and efficiently generating the conversion format PDF in batches according to the target format HTML is achieved.

[0052] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0053] It should be noted that this embodiment also provides an optional implementation, which is described in detail below.

[0054] This embodiment provides a method for batch conversion of HTML to PDF, and supports modification of report PDF style, data paging, and merging of PDF files. It is encapsulated into an executable small tool, so that business personnel can batch convert downloaded HTML reports to PDF format locally for reporting relevant data. The use of this tool does not consume the resources of the application server, and the download of batch HTML reports will basically not affect the performance of the server.

[0055] The main technical implementation of the method of this embodiment is divided into two parts, namely HTML parsing and PDF generation.

[0056] HTML parsing:

[0057] 1) Use the BufferedReader class (buffered reading class) to read all HTML data and the corresponding encoding format and store them in the FileAndEnc object;

[0058] 2) Use the HTMLparser library to parse the HTML data in the FileAndEnc object, obtain the header data and table data respectively, and store them in the Table object. In addition to the report data, the Table object also stores the report format data;

[0059] PDF Generation:

[0060] 3) Create a new PDFConfiguration class to set the format of the generated PDF;

[0061] 4) Import the itext library and use the Document class to add the contents of the Table object. Finally, use the PdfWriter class to write all the contents added to the Document to the output stream associated with the PDF file, and finally generate a PDF report.

[0062] The function list and method description are shown in Table 1. Table 1 is a function list:

[0063] Table 1 Function List

[0064]

[0065] The style of the converted PDF report can be modified through the PDFConfiguration method. The currently configurable styles are shown in Table 2, which is a list of PDF styles.

[0067]

[0068]

[0069] Figure 2 is a schematic diagram of an operation window of a data conversion tool according to an embodiment of the present application, such as Figure 2 As shown, the method flow of this embodiment is as follows:

[0070] 1. The user selects the zip package and the output PDF directory on the tool page, clicks the Generate button, and the tool first generates HTML, HTML.tmp, HTML.succ, HTML.fail directories and HTML.txt text in the PDF output path.

[0071] 2. Unzip the zip package to the HTML.tmp directory, and parse the files with the *.HTML suffix in the directory to generate PDF files. The successfully parsed HTML files are moved to the HTML.succ directory, and the failed ones are moved to the HTML.fail directory. The relevant logs are recorded in the HTML.txt text.

[0072] 3. Finally, a large PDF named with the zip package name_serial number will be generated for every 5000 PDFs.

[0073] This implementation implements a method for converting HTML to PDF, which can convert batch HTML reports into PDF format and support paging of report data and merging of PDF files. It is encapsulated into an executable gadget for easy operation by business personnel. Business personnel can first download batch reports in HTML format, and then use the gadget to convert them into PDF format to view the reports and submit files, which alleviates the consumption of application server performance caused by real-time download of batch report data and improves the robustness and task processing efficiency of the entire system.
