java poi excel给单元格增长批注(包含SXSSF)及设置列类型

package javatest; import java.io.FileOutputStream; import java.io.IOException; import org.apache.poi.xssf.usermodel.XSSFCell; import org.apache.poi.xssf.usermodel.XSSFClientAnchor; import org.apache.poi.xssf.usermodel.XSSFComment; import org.apache.poi.xssf.usermodel.XSSFDrawing; import org.apache.poi.xssf.usermodel.XSSFRichTextString; import org.apache.poi.xssf.usermodel.XSSFSheet; import org.apache.poi.xssf.usermodel.XSSFWorkbook; public class PoiWriter { public  static  void  main(String[] args)  throws IOException { // 建立工做簿对象
        XSSFWorkbook wb = new XSSFWorkbook(); // 建立工做表对象
        XSSFSheet sheet = wb.createSheet("个人工做表"); // 建立绘图对象
        XSSFDrawing p = sheet.createDrawingPatriarch(); // 建立单元格对象,批注插入到4行,1列,B5单元格
        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!")); // 添加做者,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); // 建立输出流
        FileOutputStream out = new FileOutputStream("d:/writerPostil.xlsx"); wb.write(out); // 关闭流对象
 out.close(); } }

还没有测试2003。

设置列类型的话，能够使用以下：

CellStyle css = wb.createCellStyle(); DataFormat format = wb.createDataFormat(); css.setDataFormat(format.getFormat("@")); st.setDefaultColumnStyle(colIndex,css);

 

附，poi各包的做用。

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

 

当咱们只要使用xls格式时、只要导入poi-version-yyyymmdd.jar就能够了。
当咱们还要使用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。
当咱们须要操做word、ppt、viso、outlook等时须要用到poi-scratchpad-version-yyyymmdd.jar。
