期由于项目的需求,需要word文档转pdf在线预览,由于一直没有接触这块,所以花了将近四天时间才弄明白。
写这篇文章的主要目的是加深自己的记忆,同时方便以后在用。
(最近有使用了这个功能,发现这篇文章有很多问题,已修改,抱歉)
所需要的工具openoffice
在openoffice安装成功之后,需要在安装目录下porgram文件下打开cmd命令行输入
- soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard
soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard
这时会启动两个openoffice的进程,打开任务管理器就可以看见。
需要的java包 JodConverter 下载地址 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>
<!-- 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>
在这里需要详细讲解一下openoffice的安装,最好是默认安装路径
安装完之后就开始干正事了。、
首先我们要先写一个上传页面(名字随意,我写的是jsp页面)
- <%@ page language="java" contentType="text/html; charset=utf-8"

在这里面我是加了bootstar,bootstar可以自行在百度下载。
在其up55说我在网上下载的上传图标,为了页面好看点
再接下来是controller
//这个方法是跳转到jsp的方法
@RequestMapping("/othre")
public String otre(){ return "otre"; }
- //这个方法是上传的方法
- @RequestMapping(value = "/upload", method = RequestMethod.POST)
- @ResponseBody
- public String upload(@RequestParam("file") MultipartFile file) throws IOException {
- if (!file.isEmpty()) {
- try {
- // 这里只是简单例子,文件直接输出到项目路径下。
- // 实际项目中,文件需要输出到指定位置,需要在增加代码处理。
- BufferedOutputStream out = new BufferedOutputStream(
- new FileOutputStream("d:/pdf/"+file.getOriginalFilename()));
- System.out.println(file.getOriginalFilename());
- out.write(file.getBytes());
- out.flush();
- out.close();
- } catch (FileNotFoundException e) {
- e.printStackTrace();
- return "上传失败," + e.getMessage();
- } catch (IOException e) {
- e.printStackTrace();
- return "上传失败," + e.getMessage();
- }
- //调用Doc2HtmlUtil工具类
- Doc2HtmlUtil coc2HtmlUtil = Doc2HtmlUtil.getDoc2HtmlUtilInstance();
- File file1 = null;
- FileInputStream fileInputStream = null;
- //这里写的是被转文件的路径
- file1 = new File("d:/pdf/"+file.getOriginalFilename());
- fileInputStream = new FileInputStream(file1);
- //为了后期方便,这里直接把文件名进行了截取,方便后续操作
- int i = file.getOriginalFilename().lastIndexOf(".");
- String substring = file.getOriginalFilename().substring(i);
- //上述的所有路径以及以下路劲均可自定义
- coc2HtmlUtil.file2pdf(fileInputStream, "d:/ss",substring);
- Doc2HtmlUtil doc = new Doc2HtmlUtil();
- return "上传成功";
- } else {
- return "上传失败,因为文件是空的.";
- }
- }

修改过后的代码已经可以转化pdf了,如果有什么问题可以在下方留言,我会及时回复,感谢大家的支持。
