java利用jxl导出excel_java使用jxl实现导出excel

1、导入jar包

net.sourceforge.jexcelapi

jxl

2.6

2、上代码

protected void exportExcel(HttpServletResponse response, String fileName, String[] Title,

@SuppressWarnings("rawtypes") List content) {

// 以下开始输出到EXCEL

try {

// 定义输出流,以便打开保存对话框______________________begin

OutputStream os = response.getOutputStream();// 取得输出流

response.reset();// 清空输出流

response.setHeader("Content-disposition",

"attachment; filename=" + new String(fileName.getBytes("GB2312"), "ISO8859-1"));

// 设定输出文件头

response.setContentType("application/msexcel");// 定义输出类型

// 定义输出流,以便打开保存对话框_______________________end

/** **********创建工作簿************ */

WritableWorkbook workbook = Workbook.createWorkbook(os);

/** **********创建工作表************ */

WritableSheet sheet = workbook.createSheet("Sheet1", 0);

/** **********设置纵横打印(默认为纵打)、打印纸***************** */

jxl.SheetSettings sheetset = sheet.getSettings();

sheetset.setProtected(false);

/** ************设置单元格字体************** */

WritableFont NormalFont = new WritableFont(WritableFont.ARIAL, 10);

WritableFont BoldFont = new WritableFont(WritableFont.ARIAL, 10, WritableFont.BOLD);

/** ************以下设置三种单元格样式,灵活备用************ */

// 用于标题居中

WritableCellFormat wcfCenter = new WritableCellFormat(BoldFont);

wcfCenter.setBorder(Border.ALL, BorderLineStyle.THIN); // 线条

wcfCenter.setVerticalAlignment(VerticalAlignment.CENTRE); // 文字垂直对齐

wcfCenter.setAlignment(Alignment.CENTRE); // 文字水平对齐

wcfCenter.setWrap(false); // 文字是否换行

// 用于正文居左

WritableCellFormat wcfLeft = new WritableCellFormat(NormalFont);

wcfLeft.setBorder(Border.NONE, BorderLineStyle.THIN); // 线条

wcfLeft.setVerticalAlignment(VerticalAlignment.CENTRE); // 文字垂直对齐

wcfLeft.setAlignment(Alignment.LEFT); // 文字水平对齐

wcfLeft.setWrap(false); // 文字是否换行

/** ***************以下是EXCEL第一行列标题********************* */

for (int i = 0; i < Title.length; i++) {

sheet.addCell(new Label(i, 0, Title[i], wcfCenter));

}

/** ***************以下是EXCEL正文数据********************* */

Field[] fields = null;

int i = 1;

for (Object obj : content) {

fields = obj.getClass().getDeclaredFields();

int j = 0;

for (Field v : fields) {

v.setAccessible(true);

Object va = v.get(obj);

if (va == null) {

va = "";

}

sheet.addCell(new Label(j, i, va.toString(), wcfLeft));

j++;

}

i++;

}

workbook.write();

workbook.close();

} catch (Exception e) {

logger.error("export excel failed:" + e.toString());

}

}
