springboot使用模板导出word文件

1.在pom.xml文件添加依赖

            <!-- 导出word -->
        <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.封装导出word工具类

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
     * <p>第一步生成替换后的word文件，只支持docx</p>
     * <p>第二步下载生成的文件</p>
     * <p>第三步删除生成的临时文件</p>
     * 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 {
            //这一步看具体需求，要不要删
            delFileWord(temDir, fileName);
        }
    }

    /**
     * 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();
    }
}
