Description
Technical Field
The invention relates to the technical field of java application, in particular to a method for inserting multiple attachments into a word file based on freemark.
Background
Existing freemark template engine techniques insert attachment hyperlinks into templates through code. Data mode encoded by inserting accessory base 64: firstly, according to the number and the type of the inserted attachments, manually inserting empty files of corresponding types at specified positions in a word file template in advance, storing the word file in an xml format, then finding out the positions of Base64 data corresponding to the inserted attachments, deleting Base64 data corresponding to the corresponding files, replacing the Base with $ { } placeholders, and finally storing template files in a ftl format. And reading the accessory to be inserted through Java, converting the accessory to be inserted into a Base64 code, finally replacing the $ {. X } placeholder with a value of the Base64 code of the accessory through a freemark template engine, and finally generating a word file.
However, the method of inserting hyperlinks requires that a large number of files are generated when the word file and the attachment are stored in the same directory; it is also necessary to package the file and all attachments into a compressed package when downloading the file. And the generation of the template file is complicated and needs too much manual intervention. First, a template file is created, and a file of a corresponding type is inserted in advance by finding a position corresponding to the inserted attachment. And manually saved in word xml format. The saved xml-formatted file also needs to be manually formatted. The corresponding data is deleted and replaced with placeholders. If the generated word file has a place where the attachment needs to be inserted circularly, or the number and type of the inserted attachments are unknown, the failure is easily caused. And if the operation is improper slightly, the generated word file is damaged when being opened.
