[整理]poi读取word 2007批注信息

?????? 本文非原创，只是整理了下代码，原代码出自:http://blog.chiefleo.me/archives/429.原文如下：

???????

????? 普通的读取批注信息方法:

?????

public void readWordDocxComments(String fileName) {
		XWPFDocument document = null;
		XWPFComment[] comments = null;
		try {
			document = new XWPFDocument(POIXMLDocument.openPackage(fileName));
			comments = document.getComments();
			for (int i = 0; i < comments.length; i++) {
				System.out.println("Id= " + comments[i].getId());
				System.out.println("Text= " + comments[i].getText());
				System.out.println("Author= " + comments[i].getAuthor());
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

??? 不能获取批注对应的正文信息,修改后的代码如下:
