Word,Excel,pdf,txt等文件上传并提取内容

最近项目需求：1.要用到各种文件上传，下载。

2.并对文件进行搜索。

3.只要文件中包含有搜索的内容，全部显示出来。

今天正好有时间整理一下，方便以后阅读，及对需要用到的朋友提供微薄之力。首先在实现文件上传时，使用的struts2自带的文件上传功能，通过流的方式将文件保存，在下载的时候通过流的方式写出即可。这个实现起来不是很难，主要是对各种文件内容的提取比较麻烦，比如word,excel,pdf等文件，不能使用普通的BufferedReader,BufferedWriter等流的方式读写提取，因为这些文件的格式不是普通的文本，他们有自己定义的格式，必须使用他们自己提供的jar包进行操作，Word,Excel使用的是Apache提供的poi进行操作，当然在操作的过程中要注意一些使用的方法，比如Word，Excel有不同的版本，操作的方式也不同，这里会出现很多问题，在上一篇中我整理了一些，我在操作过程出现的问题，并提供了解决方案，还有提供了本人操作这些文件的源码，下载即可使用。

一下是我在操作过程用到的详细信息：

struts.xml配置：

<action name="upload" class="lucenesAction" method="upload">

<!-- 此处可以限制上传文件类型

<interceptor-ref name="fileUpload">

上传单个文件的大小

<param name="maximumSize">500000</param>

文件的扩展名

<param name="allowedExtensions">.jsp</param>

文件的类型

<param name="allowedTypes">image/pjpeg,image/gif,text/xml,text/plain,application/msword,application/vnd.ms-excel</param>

</interceptor-ref>

<interceptor-ref name="defaultStack"/> -->

<result name="input">/demo/lucenes/upload_fail.jsp</result>

<result name="success">/demo/lucenes/upload_ok.jsp</result>

</action>

Action中用到的操作文件信息：

//下载使用的流

public InputStream tInputStream;

// 上传文件，必须的三个字段。

private File data;

// 文件名

private String dataFileName;

// 文件类型

private String dataContentType;

//省略set/get.............
