POI读取Word2007+

0

很多人使用POI读取Word的时候都会这么写：

InputStream inputStream = new FileInputStream(new File("e://company/test.docx"));
XWPFDocument document = new XWPFDocument(inputStream);
System.out.println(new XWPFWordExtractor(document).getText());

但是这个方法其实有非常多的问题的，文本框里面的内容读取不到，换行也有问题，那么这里我改进了一下：

/**
 * 处理2007+的WORD
 * @param filePath 文件地址
 * @return word内容
 */
private static String read2007(String filePath) {
	InputStream inputStream = null;
	StringBuffer content = new StringBuffer();
	try {
		inputStream = new FileInputStream(new File(filePath));
		XWPFDocument document = new XWPFDocument(inputStream);
		// 读取非表格文本框
		for (XWPFParagraph xwpfParagraph : document.getParagraphs()) {
			for(XWPFRun xwpfRun : xwpfParagraph.getRuns()) {
				content.append(getXMLContent(xwpfRun.getCTR().newCursor().xmlText())).append(NEW_LINE);
			}
		}
		// 读取表格内文本框
		for(XWPFTable xwpfTable : document.getTables()) {
			for (XWPFTableRow xwpfTableRow : xwpfTable.getRows()) {
				for (XWPFTableCell xwpfTableCell : xwpfTableRow.getTableCells()) {
					for (XWPFParagraph xwpfParagraph : xwpfTableCell.getParagraphs()) {
						for(XWPFRun xwpfRun : xwpfParagraph.getRuns()) {
							content.append(getXMLContent(xwpfRun.getCTR().newCursor().xmlText())).append(NEW_LINE);
						}
					}
				}
			}
		}
		// 读取表格内容
		for(XWPFTable xwpfTable : document.getTables()) {
			for (XWPFTableRow xwpfTableRow : xwpfTable.getRows()) {
				for (XWPFTableCell xwpfTableCell : xwpfTableRow.getTableCells()) {
					for (XWPFParagraph xwpfParagraph : xwpfTableCell.getParagraphs()) {
						content.append(xwpfParagraph.getText()).append(NEW_LINE);
					}
				}
			}
		}
		return content.toString();
	} catch (IOException e) {
		logger.error("解析word错误，文件地址：" + filePath, e);
	} finally {
		IOUtils.closeQuietly(inputStream);
	}
	return null;
}

/**
 * 获取XML内容，可以使用递归cursor.getDomNode()
 * @param xml xml
 * @return xml内容
 */
private static String getXMLContent(String xml) {
	StringBuffer content = new StringBuffer();
	Document document;
	try {
		document = DocumentHelper.parseText(xml);
		List<?> namespaces = document.getRootElement().declaredNamespaces(); // 判断是否有表格包含文本框
		boolean hasboxintab = false;
		for (Object object : namespaces) {
			Namespace namespace = (Namespace) object;
			if(NAMESPANCE_OF_TEXTBOX_IN_TABLE.equals(namespace.getPrefix())) {
				hasboxintab = true;
				break;
			}
		}
		if(!hasboxintab)
			return content.toString();
		for(Object node : document.selectNodes("//mc:Fallback//w:p")) {
			for(Object nodeb : ((Node) node).selectNodes(".//w:t")) {
				if(StringUtils.isNotEmpty(((Node) nodeb).getText()))
					content.append(((Node) nodeb).getText());
			}
			content.append(NEW_LINE);
		}
	} catch (DocumentException e) {
		logger.error("XML转化错误，内容：" + xml, e);
	}
	return content.toString();
}

2003版本简单一些：

/**
 * 处理2003的WORD
 * @param filePath 文件地址
 * @return word内容
 */
private static String read2003(String filePath) {
	InputStream inputStream = null;
	StringBuffer content = new StringBuffer();
	try {
		inputStream = new FileInputStream(new File(filePath));
		HWPFDocument document = new HWPFDocument(inputStream);
		String text = null;
		for (int i = 0; i < document.getMainTextboxRange().numParagraphs(); i++) { // 文本框
			text = document.getMainTextboxRange().getParagraph(i).text();
			if(StringUtils.isNotEmpty(text))
				content.append(text).append(NEW_LINE);
		}
		for (int i = 0; i < document.getRange().numParagraphs(); i++) { // 非文本框
			text = document.getRange().getParagraph(i).text();
			if(StringUtils.isNotEmpty(text) && StringUtils.isNotEmpty(text.trim())) // 注意这里的trim()方法否者会出现乱码
				content.append(text.trim()).append(NEW_LINE);
		}
		return content.toString();
	} catch (FileNotFoundException e) {
		logger.error("解析word错误，文件地址：" + filePath, e);
	} catch (IOException e) {
		logger.error("解析word错误，文件地址：" + filePath, e);
	} finally {
		IOUtils.closeQuietly(inputStream);
	}
	return null;
}

注意：读取出的内容为表格里面的内容，文本框内容和直接写在编辑区里面的文本，其他的一些诸如：批注，引用等一些信息可能读取不到，需要的请自行解决。
