使用openoffice转pdf，详细

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

http://www.openoffice.org/

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

[java] view plain copy

print ?

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

[java] view plain copy

print ?

<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）

[html] view plain copy

print ?

pageEncoding="utf-8"%>

opacity: 0;
-ms-filter: 'alpha(opacity=0)';
font-size: 200px;
}
</style>
</head>
<body style="padding: 10px">

            top: 0px;
            opacity: 0;
            -ms-filter: 'alpha(opacity=0)';
            font-size: 200px;
        }
    </style>
</head>
<body style="padding: 10px">

        <input type="submit" value="上传"  />
    </div>
    </form>
   <img alt="" src="${msg }">
</body>
</html>

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

[java] view plain copy

print ?

//这个方法是跳转到jsp的方法

@RequestMapping("/othre")

public String otre(){ return "otre"; }

[java] view plain copy

print ?

//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.";
}
}

//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.";  
        }  
    }

Controller中调用了word转PdF的工具类，下面是工具类

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。
