Summary of several ways to generate reports in Java

This is the second time I have written the report generation code. The last time I wrote this function, I couldn't take notes. This time I just finished writing the function and made a detailed note for later use.

Generally, we generate reports in three formats: word, excel, and pdf. Three implementations are introduced here.

1.word: use freemarker template engine technology; that is, "freemarker + xml + template";

2.excel: Use "Java + POI + Template";

3.pdf：使用“freemarker + itext + flying saucer”；
