1 需要的依赖包

<!--html操作工具--><dependency>    <groupId>org.jsoup</groupId>    <artifactId>jsoup</artifactId>    <version>1.10.2</version></dependency>

2 远程图片转为base64编码

import sun.misc.BASE64Encoder;import javax.imageio.ImageIO;import java.awt.image.BufferedImage;import java.io.*;import java.net.MalformedURLException;import java.net.URL;public class ImagesToBase64{    public static String encodeImgageToBase64(URL imageUrl) {// 将图片文件转化为字节数组字符串，并对其进行Base64编码处理        ByteArrayOutputStream outputStream = null;        try {            BufferedImage bufferedImage = ImageIO.read(imageUrl);            outputStream = new ByteArrayOutputStream();            ImageIO.write(bufferedImage, "jpg", outputStream);        } catch (MalformedURLException e1) {            e1.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        }        // 对字节数组Base64编码        BASE64Encoder encoder = new BASE64Encoder();        return encoder.encode(outputStream.toByteArray());// 返回Base64编码过的字节数组字符串    }}

Base64 在CSS中的使用

.demoImg{background-image:url("data:image/jpg;base64,/9j/4QMZRXhpZgAASUkqAAgAAAAL....");}

Base64 在HTML中的使用

3 使用springmv来接收请求并打开浏览器下载框(不支持ajax请求)

/** * * 下载简历为html * author Miss Xiao * date 2017.04.25 20:21 */@RequestMapping("downloadFile")public void downloadFile(HttpServletResponse response, HttpServletRequest request){   //基础信息   RmResumeBasiVo rmResumeBasiVo = rmResumeBasiService.selectResumeBaseVoByType(super.getUseNo(),1);   if (null!=rmResumeBasiVo) {      Long resumeNo = rmResumeBasiVo.getResumeNo();      //意向行业      RmResumeIntentionVo rmResumeIntentionVo = rmResumeIntentionService.findOneVo(resumeNo);      RmResumeJobVo jobVo = new RmResumeJobVo();      jobVo.setResumeNo(resumeNo);      //工作经验集合      List<RmResumeJobVo> jobVos = rmResumeJobService.findListVo(jobVo);      //教育背景      RmResumeEducationVo rmResumeEducationVo = rmResumeEducationService.findOneVo(resumeNo);      Date date = new Date();      //打开下载框（谷歌无效）      response.setCharacterEncoding("utf-8");      response.setContentType("multipart/form-data");      response.setHeader("Content-Disposition", "attachment;fileName="+date.getTime()+".html");      String url = request.getServletContext().getRealPath("/WEB-INF/pages/common/resume_template.html");      try {         File file=new File(url);         InputStream inputStream=new FileInputStream(file);         //获取html         Document doc = Jsoup.parse(inputStream,"UTF-8","http://www.oschina.net/");         //插入基础信息         doc.getElementById("realName").text(rmResumeBasiVo.getRealName());         doc.getElementById("headPortrait").attr("src", "data:image/jpg;base64,"+ImagesToBase64.encodeImgageToBase64(new URL(rmResumeBasiVo.getHeadPortrait())));         doc.getElementById("age").text("24");         doc.getElementById("nowLive").text(rmResumeBasiVo.getNowLive());         doc.getElementById("mobilePhone").text(rmResumeBasiVo.getMobilePhone());         doc.getElementById("email").text(rmResumeBasiVo.getEmail());         //插入意向行业信息         if (null!=rmResumeIntentionVo){            doc.getElementById("industry").text(rmResumeIntentionVo.getIndustry());

     } catch (IOException e) {         e.printStackTrace();      } catch (Exception e) {         e.printStackTrace();      }   }}

这是本人自己整合的请多指教
