Specific instructions:
1.ftl is the word template, content:

ftl production steps:

1. The dynamic data that needs to be replaced in the word template is occupied by the $ {} placeholder. Each field of the placeholder is the field you need to put in the map
2. Save word as xml format
   
3. Then use the software that can edit the xml to open it. I opened it directly with the idea. Some of them are in the wrong format. For example:
   
   directly delete the line marked with red in front of {data2} $, The guarantee is:${}such DATA2 format, all modifications
4. Then change the file suffix to ftl
5. You can run the main method and it ’s ok
