1. pom文件中引入FreeMarker依賴

<!-- freemarker jar -->
<dependency>
	<groupId>org.freemarker</groupId>
	<artifactId>freemarker</artifactId>
	<version>2.3.20</version>
</dependency>

2. 使用word 創建模板文檔如圖

3. 將word文檔另存為xml格式，同時將變量修改為${variable}格式

4.將xml文件后綴名改為ftl格式

5.將ftl文件放在/templates/目錄下

6.代碼實現：

工具類:

package com.example.demo.common;


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

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
import java.text.SimpleDateFormat;
import java.util.HashMap;
import java.util.Map;

public class CreateWordUtil {

    public static  void createWord(Map dataMap){
        try {
            //Configuration 用于讀取ftl文件
            Configuration configuration = new Configuration();
            configuration.setDefaultEncoding("utf-8");
            //獲取根目錄
            File path = new File(ResourceUtils.getURL("classpath:").getPath());
            if(!path.exists()) path = new File("");
            System.out.println("path:"+path.getAbsolutePath());
            //如果上傳目錄為/templates/，則可以如下獲取：
            File upload = new File(path.getAbsolutePath(),"templates/");
            if(!upload.exists()) upload.mkdirs();
            System.out.println("upload url:"+upload.getAbsolutePath());
            //指定路徑的第一種方式，
            //configuration.setClassForTemplateLoading();
            //指定路徑的第二種方式，具體路徑
            configuration.setDirectoryForTemplateLoading(upload);
            //輸出文檔路徑及名稱
            File outFile = new File("D:/報銷信息導出.doc");
            //以utf-8的編碼讀取ftl文件
            Template template = configuration.getTemplate("puser.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();
        }
    }
}

測試類

package com.example.demo.controller;

import com.example.demo.common.CreateWordUtil;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.text.SimpleDateFormat;
import java.util.HashMap;
import java.util.Map;

@RestController
@RequestMapping("/demo")
public class DemoController {

    @GetMapping("/test")
    public void test() {
        Map<String, Object> dataMap = new HashMap<String, Object>();
        ///姓名
        dataMap.put("name", "張三");
        //年齡
        dataMap.put("age", 15);
        //地址
        dataMap.put("address","山西省");
        //其他
        dataMap.put("other","其他");
        CreateWordUtil.createWord(dataMap);
    }
}

測試結果：

D盤目錄下正常生成文件。內容如下：
