A hypertext output method based on itext + jfreechart

Abstract

The invention provides a hypertext output component based on itext + jfreechart, belonging to the technical field of text output. The method comprises: obtaining the data needed for generating the text from the database or page first, and then classifying the data according to its representation in the text, and then numbering according to the output order of each data and corresponding with the classified data in one-to-one manner, and then generating its specific data elements according to the numbering order and the corresponding data type of the number, and adding it to the Document instance of the itext class, When the data is loaded, configuring the header and footer information of the output text through the PdfReportM1HeaderFooter class, and finally outputting the text as a pdf file type through the onCloseDocument interface. It solves the problem of complex text output very well.

Description

technical field [0001] The invention relates to text output technology, in particular to a hypertext output method based on itext+jfreechart. Background technique [0002] With the rapid development of Internet technology, more and more Internet application systems have gradually entered people's lives. In various application systems, the text output function is one of the most basic needs. Currently, the output methods for plain text files and excel files The research is relatively mature, but there is no convenient and quick method for the output of some hypertext files with complex requirements and other elements such as tables and graphics in the output. The easiest way to solve this problem is to develop a high-level An independent hypertext output component that supports complex text output requirements, improves code robustness and reusability, thereby improving development efficiency and reducing development costs. [0003] After querying and understanding various t...
