用JXL读写Excel文件
JXL是Java Excel的缩写，与名字相应，它是一个JAVA读写Excel文件的工具类，当然有另外的一个被称之为JAVA与Excel的完美解决方案POI，不过我没用过，以后再去尝试一下，因为当前做的项目的旧代码中有涉及到JXL的应用，所以就特地了解了一下，感觉就一个字，简单易用，感觉像是在用GWT的FlexTable，行列有个坐标，把相应的东西放到相应的坐标就行了，当然还有合并单元格之类的操作，很HTML Table!import jxl.*; import jxl.write.*; import java.io.*; import java.io.File.*; import java.util.*; public class excel { public static void main(String[] args) { String targetfile = "c:/out.xls";//输出的excel文件名 String worksheet = "List";//输出的excel文件工作表名 String[] title = {"ID","NAME","DESCRIB"};//excel工作表的标题 WritableWorkbook workbook; try { //创建可写入的Excel工作薄,运行生成的文件在tomcat/bin下 //workbook = Workbook.createWorkbook(new File("output.xls")); System.out.println("begin"); OutputStream os=new FileOutputStream(targetfile); workbook=Workbook.createWorkbook(os); WritableSheet sheet = workbook.createSheet(worksheet, 0); //添加第一个工作表 //WritableSheet sheet1 = workbook.createSheet("MySheet1", 1); //可添加第二个工作 /* *jxl.write.Label label = new jxl.write.Label(0, 2, "A label record"); *//put a label in cell A3, Label (column,row) *//sheet.addCell(label); */ jxl.write.Label label; for (int i=0; i<title.length; i++) { //Label(列号,行号 ,内容 ) label = new jxl.write.Label(i, 0, title); //put the title in row1 sheet.addCell(label); } //下列添加的对字体等的设置均调试通过，可作参考用 //添加数字 jxl.write.Number number = new jxl.write.Number(3, 4, 3.14159); //put the number 3.14159 in cell D5 sheet.addCell(number); //添加带有字型Formatting的对象 jxl.write.WritableFont wf = new jxl.write.WritableFont(WritableFont.TIMES,10,WritableFont.BOLD,true); jxl.write.WritableCellFormat wcfF = new jxl.write.WritableCellFormat(wf); jxl.write.Label labelCF = new jxl.write.Label(4,4,"文本",wcfF); sheet.addCell(labelCF); //添加带有字体颜色,带背景颜色 Formatting的对象 jxl.write.WritableFont wfc = new jxl.write.WritableFont(WritableFont.ARIAL,10,WritableFont.BOLD,false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.RED); jxl.write.WritableCellFormat wcfFC = new jxl.write.WritableCellFormat(wfc); wcfFC.setBackground(jxl.format.Colour.BLUE); jxl.write.Label labelCFC = new jxl.write.Label(1,5,"带颜色",wcfFC); sheet.addCell(labelCFC); //添加带有formatting的Number对象 jxl.write.NumberFormat nf = new jxl.write.NumberFormat("#.##"); jxl.write.WritableCellFormat wcfN = new jxl.write.WritableCellFormat(nf); jxl.write.Number labelNF = new jxl.write.Number(1,1,3.1415926,wcfN); sheet.addCell(labelNF); //3.添加Boolean对象 jxl.write.Boolean labelB = new jxl.write.Boolean(0,2,false); sheet.addCell(labelB); //4.添加DateTime对象 jxl.write.DateTime labelDT = new jxl.write.DateTime(0,3,new java.util.Date()); sheet.addCell(labelDT); //添加带有formatting的DateFormat对象 jxl.write.DateFormat df = new jxl.write.DateFormat("ddMMyyyyhh:mm:ss"); jxl.write.WritableCellFormat wcfDF = new jxl.write.WritableCellFormat(df); jxl.write.DateTime labelDTF = new jxl.write.DateTime(1,3,new java.util.Date(),wcfDF); sheet.addCell(labelDTF); //和宾单元格 //sheet.mergeCells(int col1,int row1,int col2,int row2);//左上角到右下角 sheet.mergeCells(4,5,8,10);//左上角到右下角 wfc = new jxl.write.WritableFont(WritableFont.ARIAL,40,WritableFont.BOLD,false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.GREEN); jxl.write.WritableCellFormat wchB = new jxl.write.WritableCellFormat(wfc); wchB.setAlignment(jxl.format.Alignment.CENTRE); labelCFC = new jxl.write.Label(4,5,"单元合并",wchB); sheet.addCell(labelCFC); // //设置边框 jxl.write.WritableCellFormat wcsB = new jxl.write.WritableCellFormat(); wcsB.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THICK); labelCFC = new jxl.write.Label(0,6,"边框设置",wcsB); sheet.addCell(labelCFC); workbook.write(); workbook.close(); } catch (Exception e) { e.printStackTrace(); } System.out.println("end"); Runtime r=Runtime.getRuntime(); Process p=null; //String cmd[]={"notepad","exec.java"}; String cmd[]={"C:\\Program Files\\Microsoft Office\\Office\\EXCEL.EXE","out.xls"}; try { p=r.exec(cmd); } catch(Exception e) { System.out.println("error executing: "+cmd); } } }
