把office文档转化为pdf并在线显示_openoffice3.3-优快云博客

本文链接：https://blog.youkuaiyun.com/walkcode/article/details/6424998

1.下载jodconverter-2.2.2，使用这个里面lib下面的所有jar包。这些jar包放在WEB-INF的lib文件夹里面。

2.下载"Openoffice3.3或3.3"，并进行安装。OpenOffice的下载地址是"http://sourceforge.net/projects/jodconverter/files/"

3、以cmd方式启动openoffice server

cd opeonofiice的安装路径/program

soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard

4.安装Adobe Reader或其他pdf阅读器

5.下面进行代码的编写。

JOD4DocToPDF这个类用来把office文档转换成pdf.需要指出的是里面的“/”最好写成File.separator,这样程序的可移植性就比较好了

package bao1;
import java.io.File;
import java.net.ConnectException;
import java.util.Date;

import com.artofsolving.jodconverter.DocumentConverter;
import com.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection;
import com.artofsolving.jodconverter.openoffice.connection.SocketOpenOfficeConnection;
import com.artofsolving.jodconverter.openoffice.converter.OpenOfficeDocumentConverter;

public class JOD4DocToPDF extends java.lang.Thread {
    private File inputFile;// 需要转换的文件
    private File outputFile;// 输出的文件

    public JOD4DocToPDF(File inputFile, File outputFile) {
        this.inputFile = inputFile;
        this.outputFile = outputFile;

    }

    public void docToPdf() {
        Date start = new Date();

        OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
        try {
            connection.connect();


            DocumentConverter converter = new OpenOfficeDocumentConverter(
                    connection);
            converter.convert(inputFile, outputFile);
        } catch (ConnectException cex) {
            cex.printStackTrace();
        } finally {
            // close the connection
            if (connection != null) {
                connection.disconnect();
                connection = null;
            }
        }
          }

    /**
     * 由于服务是线程不安全的，所以……需要启动线程
     */
    public void run() {
        this.docToPdf();

    }

    public File getInputFile() {
        return inputFile;
    }

    public void setInputFile(File inputFile) {
        this.inputFile = inputFile;
    }

    public File getOutputFile() {
        return outputFile;
    }

    public void setOutputFile(File outputFile) {
        this.outputFile = outputFile;
    }


}

下面开始编写jsp来遍历站点根目录下的“wendang”文件夹，这里也使用了一些AJAX。

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>遍历文件</title>
<script language="javascript">
  var xmlHttp ;
  var flag = false ;
  function createXMLHttp(){
   if(window.XMLHttpRequest){
    xmlHttp = new XMLHttpRequest() ;
   } else {
    xmlHttp = new ActiveXObject("Microsoft.XMLHTTP") ;
   }
  }
  function checkUserid(mc){
   createXMLHttp() ;

xmlHttp.open("POST","chuli.jsp?mc="+mc) ;

   xmlHttp.onreadystatechange = checkUseridCallback ;
   xmlHttp.send(null) ;
   document.getElementById("msg").innerHTML ="<img src='images/loading3.gif'/>" ;
     }
  function checkUseridCallback(){
   if(xmlHttp.readyState == 4){
    if(xmlHttp.status == 200){
     var text = xmlHttp.responseText ;
     document.getElementById("msg").innerHTML = text ;
    }
   }
  }
</script>
<style type="text/css">
#msg
{
margin-left:40px;

}
</style>
</head>
<body>
    <center>
      <div id="msg2"></div>
    </center>

<div id="msg">
<%

   java.io.File f=new java.io.File(this.getServletContext().getRealPath("/")+"wendang");

   String f2[]=f.list();
   for(int i=0;i<f2.length;i++)
   {
   %>

       <li><a href="#" onclick="checkUserid('<%=f2[i]%>')"><%=f2[i]%></a></li>
   <%
   }
   %>

   </div>
</body>
</html>

这个jsp负责把office文档转换成pdf，为了简单起见这里只生成一个名为“123.pdf”的临时文件

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page import="java.net.URLDecoder" %>
<%@ page import="bao1.JOD4DocToPDF" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>显示文档</title>

</head>
<body>
<%
request.setCharacterEncoding("UTF-8");
//String s=URLDecoder.decode(request.getParameter("mc"),"ISO-8859-1");
String s=new String(request.getParameter("mc").getBytes("ISO8859-1"),"GB2312");

String path=this.getServletContext().getRealPath("/")+"wendang"+java.io.File.separator;
String path2=this.getServletContext().getRealPath("/")+"pdf"+java.io.File.separator;

JOD4DocToPDF zh=new JOD4DocToPDF(new java.io.File(path+s),new java.io.File(path2+"123.pdf"));

zh.start();
%>

<%
Thread.sleep(4000); //因为把office文档转换成pdf需要大概4秒时间，这个时间不是用来显示而是用来替换原来的pdf.之后显示才不会出错
%>
