java poi excel給單元格增長批註(包含SXSSF)及設置列類型

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 { // 建立工做簿對象
        XSSFWorkbook wb = new XSSFWorkbook(); // 建立工做表對象
        XSSFSheet sheet = wb.createSheet("個人工做表"); // 建立繪圖對象
        XSSFDrawing p = sheet.createDrawingPatriarch(); // 建立單元格對象,批註插入到4行,1列,B5單元格
        XSSFCell cell = sheet.createRow(4).createCell(1); // 插入單元格內容
        cell.setCellValue(new XSSFRichTextString("批註")); // 獲取批註對象 // (int dx1, int dy1, int dx2, int dy2, short col1, int row1, short // col2, int row2) // 前四個參數是座標點,後四個參數是編輯和顯示批註時的大小.
        XSSFComment comment = p.createCellComment(new XSSFClientAnchor(0, 0, 0,0, (short) 3, 3, (short) 5, 6)); // 輸入批註信息
        comment.setString(new XSSFRichTextString("這是批註內容!")); // 添加做者,選中B5單元格,看狀態欄
        comment.setAuthor("toad"); // 將批註添加到單元格對象中
 cell.setCellComment(comment); // 建立輸出流
        FileOutputStream out = new FileOutputStream("d:/writerPostil.xlsx"); wb.write(out); // 關閉流對象
 out.close(); } }

還沒有測試2003。

設置列類型的話，能夠使用以下：

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

 

當咱們只要使用xls格式時、只要導入poi-version-yyyymmdd.jar就能夠了。
當咱們還要使用xlsx格式、還要導入poi-ooxml-version-yyyymmdd.jar。
至於poi-ooxml-schemas-version-yyyymmdd.jar這個jar基本不太會用到的。
當咱們須要操做word、ppt、viso、outlook等時須要用到poi-scratchpad-version-yyyymmdd.jar。
