@GetMapping("/test")
    public void test() {
        Map dataMap = new HashMap<>();
        ///姓名
        dataMap.put("name", "张三");
        CreateWordUtil.createWord(dataMap);
    }

test.ftl 放入 resource/templates文件夹中 

import freemarker.template.Configuration;
import freemarker.template.Template;
import org.springframework.util.ResourceUtils;

import java.io.*;
import java.util.Map;

public class CreateWordUtil {

    public static void createWord(Map dataMap) {
        try {
            //Configuration 用于读取ftl文件
            Configuration configuration = new Configuration();
            configuration.setDefaultEncoding("utf-8");
            //获取根目录
            File path = new File(ResourceUtils.getURL("classpath:").getPath());
            if (!path.exists()) path = new File("");
            System.out.println("path:" + path.getAbsolutePath());
            //如果上传目录为/templates/，则可以如下获取：
            File upload = new File(path.getAbsolutePath(), "templates/");
            if (!upload.exists()) upload.mkdirs();
            System.out.println("upload url:" + upload.getAbsolutePath());
            //指定路径的第一种方式，
            //configuration.setClassForTemplateLoading();
            //指定路径的第二种方式，具体路径
            configuration.setDirectoryForTemplateLoading(upload);
            //输出文档路径及名称
            File outFile = new File("test.doc");
            //以utf-8的编码读取ftl文件
            Template template = configuration.getTemplate("test.ftl", "utf-8");
            Writer out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(outFile), "utf-8"), 10240);
            template.process(dataMap, out);
            out.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

创建模板文件-test.ftl 

1. 创建word 

2. 另存为 Xml文件

 3. 修改拓展名重命名 ftl

编辑变量，根据自己的业务需求创建动态变量，变量语法可参考Freemark 语法
