Use OpenOffice to PDF, detailed

Recently because of the project needs, the Word document to the PDF online preview, because there has been no contact with this piece, so it took nearly four days to figure out.

The main purpose of writing this article is to deepen your memory, and at the same time make it easier to use later.

(Recently used this feature, found that this article has a lot of problems, have been modified, sorry)

The tools needed are OpenOffice

http://www.openoffice.org/

After the OpenOffice installation is successful, you need to open the CMD command-line input under the Porgram file under the installation directory

Soffice-headless-accept= "SOCKET,HOST=127.0.0.1,PORT=8100;URP;"-nofirststartwizard

A two-OpenOffice process is started and can be seen by opening task Manager.

Required Java package jodconverter download address http://sourceforge.net/projects/jodconverter/files/JODConverter/

Pom.xml

<!--https://mvnrepository.com/artifact/com.artofsolving/jodconverter-maven-plugin-->
<dependency >
<groupId>com.artofsolving</groupId>
<artifactid>jodconverter-maven-plugin</ Artifactid>
<version>2.2.1</version></dependency>

Here you need to explain in detail the installation of OpenOffice, preferably the default installation path

After the installation, we started doing business. 、

First we have to write an upload page (name at random, I wrote the JSP page)

<%@ 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" > In this side I was added Bootstar,bootstar can be downloaded in Baidu.
In its up55 said I downloaded the upload icon on the web, for the page to look good point

And then there's controller.

 
This method is a way to jump to the JSP

@RequestMapping ("/othre") public String Otre () {return "Otre";}

This method is the method of uploading @RequestMapping (value = "/upload", methods = requestmethod.post) @ResponseBody public String Uplo  
                AD (@RequestParam ("file") Multipartfile file) throws IOException {if (!file.isempty ()) {try {  
                Here is just a simple example where the file is output directly to the project path.  
                  
         
                In the actual project, the file needs to be output to the specified location, requiring additional code processing. Bufferedoutputstream out = new Bufferedoutputstream (New FileOutputStream ("d:/pdf/" +file.getorig  
                Inalfilename ()));  
                System.out.println (File.getoriginalfilename ());  
                Out.write (File.getbytes ());  
                Out.flush ();  
            Out.close ();  
                catch (FileNotFoundException e) {e.printstacktrace ();  
            Return "Upload failed," + e.getmessage ();  
                catch (IOException e) {e.printstacktrace ();  
            Return "Upload failed," + e.getmessage (); }//Call Doc2htmluTil tool class Doc2htmlutil coc2htmlutil = Doc2htmlutil.getdoc2htmlutilinstance ();  
            File file1 = null;  
            FileInputStream fileinputstream = null; 

            Here is the path to the transferred file File1 = new file ("d:/pdf/" +file.getoriginalfilename ());  

FileInputStream = new FileInputStream (file1);  
            For later convenience, the file name is intercepted directly, which facilitates subsequent operations int i = File.getoriginalfilename (). LastIndexOf (".");
            String substring = file.getoriginalfilename (). substring (i);  
            All of the above paths and the following road strength can be customized coc2htmlutil.file2pdf (FileInputStream, "d:/ss", substring);  
              
              
            Doc2htmlutil doc = new Doc2htmlutil ();  
              
              
        Return "upload success";  
        else {return "upload failed because the file is empty." }  
    }

After the modified code has been able to convert the PDF, if there are any questions can be left at the bottom of the message, I will promptly reply, thank you for your support.
