JAVA uses freemarker template to export Word

1. Import the jar package

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>

2. Make templates, modify word

First replace the fields that need to be filled in word with ${}

Then change the suffix to ftl

3. Modify the JAVA code

    public static void export(Map<String,Object> map){
