下面我们就来简单看一下这些jar包的对文档的读取的应用实例：

pom坐标为:

.....
<properties>
<poi.version>3.13</poi.version>
<pdf.version>1.8.10</pdf.version>
</properties>
....
<!-- 3个jar版本必须统一 -->

读取内容代码

public static String getPDFContent(File file) {
String context = null;
InputStream f = null;
try {
f = new FileInputStream(file);
PDFParser p = new PDFParser(f);
p.parse();
PDDocument pdd = p.getPDDocument();
PDFTextStripper ts = new PDFTextStripper();
context = ts.getText(pdd);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
f.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return context == null ? "" : context;
}

public static String getXLSContent(File file) {

StringBuilder sb = new StringBuilder();
InputStream f = null;
try {
f = new FileInputStream(file);
jxl.Workbook rwb = Workbook.getWorkbook(f);
Sheet[] sheet = rwb.getSheets();
for (int i = 0; i < sheet.length; i++) {
Sheet rs = rwb.getSheet(i);
for (int j = 0; j < rs.getRows(); j++) {
Cell[] cells = rs.getRow(j);
for (int k = 0; k < cells.length; k++)
sb.append(cells[k].getContents());
}
}
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
f.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString() == null ? null : sb.toString();
}

public static String getWord2003(File file) {
String word2003 = null;
InputStream f = null;
try {
f = new FileInputStream(file);
WordExtractor ex = new WordExtractor(f);
word2003 = ex.getText();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
f.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return word2003;
}

public static String getWord2007(File file) {
String word2007 = null;
try {
OPCPackage opcPackage = POIXMLDocument
.openPackage(file.getParent());
POIXMLTextExtractor extractor = new XWPFWordExtractor(opcPackage);
word2007 = extractor.getText();
} catch (Exception e) {
e.printStackTrace();
}
return word2007;
}

另外 我把获取文件的MIME方法也写上吧

public static String getFileMime(File file) {
if (!file.exists()) {
System.err.println("文件不存在");
return null;
}
MagicMatch match = null;
try {
match = Magic.getMagicMatch(file, false);
} catch (Exception e) {
e.printStackTrace();
}
return match.getMimeType();
}
