In some service scenarios, a report document needs to be generated by combining actual production data according to a fixed format, a general implementation mode is a mode based on text variable replacement, a document needs to be replaced by traversing a text when being generated, then a poi is used for generating the document, and the document needs to be repackaged and compiled after the post-modification, which is inconvenient for maintenance and has no good implementation mode for generating pictures in the document. FreeMarker is a template engine that is based on templates and data to be changed and used to generate output text (HTML web pages, emails, configuration files, source code, etc.). The Template is written as Freemarker Template Language (FTL). It is a simple, proprietary language, not as sophisticated as PHP programming languages. In the template, attention may be paid to how the data is presented, and outside the template attention may be paid to what data is to be presented. In order to more flexibly realize generation of the docx document, facilitate later maintenance and realize the function of displaying pictures in the document, further improvement is needed.

And (3) generating xml: and (3) transmitting the inquired data into a ftl template through a specified ftl template, outputting by a freemarker to generate an xml file, wherein the position of the generated xml file is positioned under a word directory.
Inquiring data when generating the picture: and querying data needing to be shown in the document from the database, wherein the data type is Map. Front-end rendering: rendering into a chart using the queried data using Echarts, and acquiring content in the Base64 format. Back-end generation: when receiving the pictures in the Base64 format, the back end converts the Base64 into the pictures in the png format and stores the pictures in the word \ media directory.
