前端請求程式碼：
function preview(custcode,tempId){ layer.open({ type: 2, title: '簡歷預覽', maxmin: true, scrollbar: false, shadeClose: true, //點選遮罩關閉層 area : ['800px' , '600px'], content: '<%=path %>/demandFollow/previewWordsByCode.do?custcode='+custcode+'&tempId='+tempId, /* success: function(layero, index) { var body = layer.getChildFrame('html', index); $(body).height("600px"); layer.iframeAuto(index); } */ }) }
後臺處理：
@RequestMapping("/previewWordsByCode") public ModelAndView previewWordsByCode(@RequestParam(value = "custcode", defaultValue = "") String custcode, @RequestParam(value = "tempId", defaultValue = "0") Integer tempId, HttpServletRequest request, HttpServletResponse response) { ModelAndView mv = new ModelAndView("pdf2"); Map<String, Object> paramMap = new HashMap<>(); paramMap.put("custcode", custcode); paramMap.put("tempId", tempId); String url = personalinMapper.selresumeUrlByMap(paramMap); String contextPath = request.getSession().getServletContext().getRealPath("/"); response.setContentType("text/html;charset=UTF-8"); // 呼叫已流的方式傳輸檔案的方法 String fullPath = ""; fullPath = contextPath + url; if (new File(fullPath).exists() == false) { mv.addObject("msg", "使用者還沒有簡歷<br>" + fullPath); mv.addObject("status", 1); } else {// 如果有這個檔案先轉換 String savePath = fullPath.substring(0, fullPath.lastIndexOf(".")) + ".pdf"; if (new File(savePath).exists() == false) { WordPdfUtil.doc2pdf(fullPath, savePath); } url = url.replace("\\", "/"); url = url.substring(0, url.lastIndexOf(".")) + ".pdf"; mv.addObject("msg", url); mv.addObject("status", 0); } return mv; }
工具類：
package com.shzqoa.util; import java.io.File; import java.io.FileOutputStream; import java.io.InputStream; import org.aspectj.weaver.ast.Test; import com.aspose.words.Document; import com.aspose.words.License; import com.aspose.words.SaveFormat; public class WordPdfUtil { public static void doc2pdf(String inPath, String outPath) { try { //long old = System.currentTimeMillis(); File file = new File(outPath); // 新建一個空白pdf文件 FileOutputStream os = new FileOutputStream(file); Document doc = new Document(inPath); // Address是將要被轉化的word文件 doc.save(os, SaveFormat.PDF);// 全面支援DOC, DOCX, OOXML, RTF HTML, OpenDocument, PDF, // EPUB, XPS, SWF 相互轉換 //long now = System.currentTimeMillis(); //System.out.println(outPath+"生成共耗時：" + ((now - old) / 1000.0) + "秒"); // 轉化用時 if (os != null) { os.close(); } } catch (Exception e) { e.printStackTrace(); } }
所需jar包： aspose-words-15.8.0-jdk16.jar
將pdf反映到jsp頁面上：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
%>
<!DOCTYPE html>
<html>
<head>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<title>Insert title here</title>
</head>
<body>
<c:if test="${status==0 }">
<iframe name="resource" src="<%=path %>${msg }" width="800px" height="600px" scrolling="yes" frameborder="0"></iframe>
</c:if>
<c:if test="${status==1 }">
<h3>還沒有生成簡歷</h3>
</c:if>
</body>
</html>
