> 转这篇文章，一来是给自己做个笔记。二来是进行补充，让更多人更好的受益。

#### 1、导入maven ####

<dependency>
 <groupId>cn.afterturn</groupId>
 <artifactId>easypoi-base</artifactId>
 <version>3.0.3</version>
 </dependency>
 <dependency>
 <groupId>cn.afterturn</groupId>
 <artifactId>easypoi-web</artifactId>
 <version>3.0.3</version>
 </dependency>
 <dependency>
 <groupId>cn.afterturn</groupId>
 <artifactId>easypoi-annotation</artifactId>
 <version>3.0.3</version>
 </dependency>

#### 2、封装utils ####

package com.xdx97.party.common.utils.word;
 
 import cn.afterturn.easypoi.word.WordExportUtil;
 import org.apache.poi.xwpf.usermodel.XWPFDocument;
 import org.springframework.util.Assert;
 
 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;
 import java.io.File;
 import java.io.FileOutputStream;
 import java.io.OutputStream;
 import java.net.URLEncoder;
 import java.util.Map;
 
 public class ExportWordUtils {
 /**
 * 导出word
 * 第一步生成替换后的word文件，只支持docx
 * 第二步下载生成的文件
 * 第三步删除生成的临时文件
 * 模版变量中变量格式：{
 {foo}}
 * @param templatePath word模板地址
 * @param temDir 生成临时文件存放地址
 * @param fileName 文件名
 * @param params 替换的参数
 * @param request HttpServletRequest
 * @param response HttpServletResponse
 */
 public static void exportWord(String templatePath, String temDir, String fileName, Map<String, Object> params, HttpServletRequest request, HttpServletResponse response) {
 Assert.notNull(templatePath,"模板路径不能为空");
 Assert.notNull(temDir,"临时文件路径不能为空");
 Assert.notNull(fileName,"导出文件名不能为空");
 Assert.isTrue(fileName.endsWith(".docx"),"word导出请使用docx格式");
 if (!temDir.endsWith("/")){
 temDir = temDir + File.separator;
 }
 File dir = new File(temDir);
 if (!dir.exists()) {
 dir.mkdirs();
 }
 try {
 String userAgent = request.getHeader("user-agent").toLowerCase();
 if (userAgent.contains("msie") || userAgent.contains("like gecko")) {
 fileName = URLEncoder.encode(fileName, "UTF-8");
 } else {
 fileName = new String(fileName.getBytes("utf-8"), "ISO-8859-1");
 }
 XWPFDocument doc = WordExportUtil.exportWord07(templatePath, params);
 String tmpPath = temDir + fileName;
 FileOutputStream fos = new FileOutputStream(tmpPath);
 doc.write(fos);
 // 设置强制下载不打开
 response.setContentType("application/force-download");
 // 设置文件名
 response.addHeader("Content-Disposition", "attachment;fileName=" + fileName);
 OutputStream out = response.getOutputStream();
 doc.write(out);
 out.close();
 } catch (Exception e) {
 e.printStackTrace();
 } finally {
 delFileWord(temDir,fileName);//这一步看具体需求，要不要删
 }
 }
 /**
 * 删除零时生成的文件
 */
 public static void delFileWord(String filePath, String fileName){
 File file =new File(filePath+fileName);
 File file1 =new File(filePath);
 file.delete();
 file1.delete();
 }
 }

#### 3、创建word模板 ####

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L1RvbXdpbGRib2Fy_size_16_color_FFFFFF_t_70]

#### 4、测试代码 ####

package com.xdx97.party.service.api.common;
 
 import com.xdx97.party.common.utils.word.ExportWordUtils;
 import org.springframework.stereotype.Controller;
 import org.springframework.web.bind.annotation.RequestMapping;
 
 import javax.servlet.http.HttpServletRequest;
 import javax.servlet.http.HttpServletResponse;
 import java.util.HashMap;
 import java.util.Map;
 
 @Controller
 public class Demo {
 
 @RequestMapping("/demo/export")
 public void export(HttpServletRequest request, HttpServletResponse response){
 Map<String,Object> params = new HashMap<>();
 params.put("title","这是标题");
 params.put("name","李四");
 //这里是我说的一行代码
 ExportWordUtils.exportWord("word/export.docx","F:/test","aaa.docx",params,request,response);
 }
 }

**测试代码和word模板相对位置**

#### 测试结果 ####
