        XSSFCell cell = sheet.createRow(4).createCell(1);

        // 插入单元格内容

        cell.setCellValue(new XSSFRichTextString("批注"));

        // 获取批注对象

        // (int dx1, int dy1, int dx2, int dy2, short col1, int row1, short

        // col2, int row2)

        // 前四个参数是坐标点,后四个参数是编辑和显示批注时的大小.

        XSSFComment comment = p.createCellComment(new XSSFClientAnchor(0, 0, 0,0, (short) 3, 3, (short) 5, 6));

        // 输入批注信息

        comment.setString(new XSSFRichTextString("这是批注内容!"));

        // 添加作者,选中B5单元格,看状态栏

        comment.setAuthor("toad");

        // 将批注添加到单元格对象中

        cell.setCellComment(comment);

        // 创建输出流

        FileOutputStream out = new FileOutputStream("d:/writerPostil.xlsx");

        wb.write(out);

        // 关闭流对象

        out.close();

    }

}

设置列类型的话，可以使用如下：

CellStyle css = wb.createCellStyle();

DataFormat  format = wb.createDataFormat();

css.setDataFormat(format.getFormat("@"));

st.setDefaultColumnStyle(colIndex,css);

附，poi各包的作用。

The Apache POI distribution consists of support for many document file formats. This support is provided in several Jar files. Not all of the Jars are needed for every format. The following tables show the relationships between POI components, Maven repository tags, and the project's Jar files.

Component	Application type	Maven artifactId	Notes
POIFS	OLE2 Filesystem	poi	Required to work with OLE2 / POIFS based files
HPSF	OLE2 Property Sets	poi
HSSF	Excel XLS	poi	For HSSF only, if common SS is needed see below
HSLF	PowerPoint PPT	poi-scratchpad
HWPF	Word DOC	poi-scratchpad
HDGF	Visio VSD	poi-scratchpad
HPBF	Publisher PUB	poi-scratchpad
HSMF	Outlook MSG	poi-scratchpad
OpenXML4J	OOXML	poi-ooxml plus one of poi-ooxml-schemas, ooxml-schemas	Only one schemas jar is needed, see below for differences
XSSF	Excel XLSX	poi-ooxml
XSLF	PowerPoint PPTX	poi-ooxml
XWPF	Word DOCX	poi-ooxml
Common SS	Excel XLS and XLSX	poi-ooxml	WorkbookFactory and friends all require poi-ooxml, not just core poi

当我们只要使用xls格式时、只要导入poi-version-yyyymmdd.jar就可以了。
当我们还要使用xlsx格式、还要导入poi-ooxml-version-yyyymmdd.jar。
至于poi-ooxml-schemas-version-yyyymmdd.jar这个jar基本不太会用到的。
当我们需要操作word、ppt、viso、outlook等时需要用到poi-scratchpad-version-yyyymmdd.jar。
