我写了这个简单的程序:
public class WriteExcel {
private WritableCellFormat timesBoldUnderline;
private WritableCellFormat times;
private String inputFile;
public void setOutputFile(String inputFile) {
this.inputFile = inputFile;
}
public void write() throws IOException, WriteException {
File file = new File(inputFile);
WorkbookSettings wbSettings = new WorkbookSettings();
wbSettings.setLocale(new Locale("en", "EN"));
WritableWorkbook workbook = Workbook.createWorkbook(file, wbSettings);
workbook.createSheet("Report", 0);
WritableSheet excelSheet = workbook.getSheet(0);
createLabel(excelSheet);
createContent(excelSheet);
workbook.write();
workbook.close();
}
private void createLabel(WritableSheet sheet) throws WriteException {
// Lets create a times font
WritableFont times10pt = new WritableFont(WritableFont.TIMES, 10);
// Define the cell format
times = new WritableCellFormat(times10pt);
// Lets automatically wrap the cells
times.setWrap(true);
// Create create a bold font with unterlines
WritableFont times10ptBoldUnderline = new WritableFont(
WritableFont.TIMES, 10, WritableFont.BOLD, false,
UnderlineStyle.SINGLE);
timesBoldUnderline = new WritableCellFormat(times10ptBoldUnderline);
// Lets automatically wrap the cells
timesBoldUnderline.setWrap(true);
CellView cv = new CellView();
cv.setFormat(times);
cv.setFormat(timesBoldUnderline);
cv.setAutosize(true);
// Write a few headers
addCaption(sheet, 0, 0, "Header 1");
addCaption(sheet, 1, 0, "This is another header");
}
private void createContent(WritableSheet sheet) throws WriteException,
RowsExceededException {
// Write a few number
for (int i = 1; i < 10; i++) {
// First column
addNumber(sheet, 0, i, i + 10);
// Second column
addNumber(sheet, 1, i, i * i);
}
// Lets calculate the sum of it
StringBuffer buf = new StringBuffer();
buf.append("SUM(A2:A10)");
Formula f = new Formula(0, 10, buf.toString());
sheet.addCell(f);
buf = new StringBuffer();
buf.append("SUM(B2:B10)");
f = new Formula(1, 10, buf.toString());
sheet.addCell(f);
// Now a bit of text
for (int i = 12; i < 20; i++) {
// First column
addLabel(sheet, 0, i, "Boring text " + i);
// Second column
addLabel(sheet, 1, i, "Another text");
}
}
private void addCaption(WritableSheet sheet, int column, int row, String s)
throws RowsExceededException, WriteException {
Label label;
label = new Label(column, row, s, timesBoldUnderline);
sheet.addCell(label);
}
private void addNumber(WritableSheet sheet, int column, int row,
Integer integer) throws WriteException, RowsExceededException {
Number number;
number = new Number(column, row, integer, times);
sheet.addCell(number);
}
private void addLabel(WritableSheet sheet, int column, int row, String s)
throws WriteException, RowsExceededException {
Label label;
label = new Label(column, row, s, times);
sheet.addCell(label);
}
public static void main(String[] args) throws WriteException, IOException {
WriteExcel test = new WriteExcel();
test.setOutputFile("C:/Users/test/Desktop/Output");
test.write();
System.out.println("Please check the result file!");
}
}
当我运行程序时,我得到:
Exception in thread "main" java.io.FileNotFoundException: C:\Users\test\Desktop\Output (Access denied)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(FileOutputStream.java:194)
at java.io.FileOutputStream.<init>(FileOutputStream.java:145)
at jxl.Workbook.createWorkbook(Workbook.java:301)
at excelProcessor.WriteExcel.write(WriteExcel.java:37)
at excelProcessor.WriteExcel.main(WriteExcel.java:126)
我的问题是我无法输出文件。当我这样做时,我得到了这个例外。我正在运行一win 7
台带有 eclipseJuno Service Release 2
和JDK 1.6
. 我也尝试以管理员身份启动 eclipse,但是,它不起作用。
我真的很感激你的回答!
更新
我的例外点在这里:
WritableWorkbook workbook = Workbook.createWorkbook(file, wbSettings);
但是,不知道要改什么...
