Java导出2003、2007版Excel

创建用于添加表头的实体类

/**
 * excel导出标题显示值
 * @author Terisadeng
 *
 */
public class KeyValue {
	private String key;
	private String value;
	public String getKey() {
		return key;
	}
	
	public KeyValue(){}
	
	public KeyValue(String key, String value) {
		super();
		this.key = key;
		this.value = value;
	}

	public void setKey(String key) {
		this.key = key;
	}
	public String getValue() {
		return value;
	}
	public void setValue(String value) {
		this.value = value;
	}
}

定义生成文件名的方法

/**
	 * 
	 * Description: 设置导出xls格式Excel文件的文件名 by Terisadeng
	 * Implement: 
	 * @return 
	 * @see
	 */ 
public static String getFileName() {
		SimpleDateFormat sf = new SimpleDateFormat("yyyyMMddHHmm");
		StringBuilder sb = new StringBuilder();
		sb.append(sf.format(System.currentTimeMillis()));
		sb.append(".xls");
		return sb.toString();
	}
	
/**
	 * 
	 * Description: 设置导出xlsx格式Excel文件的文件名 by Terisadeng
	 * Implement: 
	 * @return 
	 * @see
	 */
	public static String getFileName2007() {
        SimpleDateFormat sf = new SimpleDateFormat("yyyyMMddHHmm");
        StringBuilder sb = new StringBuilder();
        sb.append(sf.format(System.currentTimeMillis()));
        sb.append(".xlsx");
        return sb.toString();
    }

输出流设置导出文件名

/**
	 * 设置头信息
	 * 
	 * @param response
	 *            HttpServletResponse
	 * @param fileName
	 *            默认的文件名称
	 */
	public static void setExcelContentType(HttpServletResponse response,
			String fileName) {
		try {
			fileName = new String(fileName.getBytes(), "utf-8");
		} catch (UnsupportedEncodingException e) {
			// should no happen
		}
		response.reset();
		response.setContentType("application/msexcel;charset=utf-8");
		response.setHeader("Content-disposition", "attachment;filename= "
				+ fileName);
	}

1、导出2003版Excel

入参是前台传入的HttpServletResponse对象、需要导出的List>类型的数据集、List类型的表头、excel中sheet的名称

public static void write(HttpServletResponse response,
			List> listMaps, List keyValueList,String title) {
		//设置导出的文件名，按当前时间设置
		setExcelContentType(response, getFileName());
		//创建工作簿对象
		WritableWorkbook wwbook = null;
		OutputStream os = null;
		try {
		  //设置输出流对象
			os = response.getOutputStream();
			//根据输出流对象创建初始化工作簿对象
			wwbook = jxl.Workbook.createWorkbook(os);
			//根据入参title创建Sheet对象
			WritableSheet wsheet = wwbook.createSheet(title, 0);// set sheet
			//根据入参keyValueList设置表头
			for (int i = 0; i < keyValueList.size(); i++) { // set header title
				jxl.write.Label titleCell = new jxl.write.Label(i, 0,
						keyValueList.get(i).getValue());
				wsheet.addCell(titleCell);
			}
			//按照表头创建行对象
			for (int i = 1; i <= listMaps.size(); i++) { // set value
				Map map = listMaps.get(i - 1);
				for (int j = 0; j < keyValueList.size(); j++) {
					KeyValue keyValue = keyValueList.get(j);
					jxl.write.Label valueCell = new jxl.write.Label(j, i, (map
							.get(keyValue.getKey()) != null) ? map.get(
							keyValue.getKey()).toString() : "");
					//添加到sheet中
					wsheet.addCell(valueCell);
					
				}
			}
			
			wwbook.write();
		} catch (IOException e) {
			e.printStackTrace();
		} catch (RowsExceededException e) {
			e.printStackTrace();
		} catch (WriteException e) {
			e.printStackTrace();
		} catch (IllegalArgumentException e) {
			e.printStackTrace();
		} finally {
			try {
				wwbook.close();
				os.close();
			} catch (IOException ie) {
				ie.printStackTrace();
			} catch (WriteException e) {
				e.printStackTrace();
			}
		}
	}

2、导出2007版Excel
入参是前台传入的HttpServletResponse对象、需要导出的List>类型的数据集、List类型的表头、excel中sheet的名称

public static void write2007(HttpServletResponse response,
            List> listMaps, List keyValueList,String title) {
        //设置导出的文件名，按当前时间设置
        setExcelContentType(response, getFileName2007());
        //创建工作簿对象
        XSSFWorkbook wb = new XSSFWorkbook();
        OutputStream os = null;
        try {
        		//设置输出流对象
            os = response.getOutputStream();
            //根据入参title创建Sheet对象
            XSSFSheet sheet = wb.createSheet(title);// set sheet
            //创建Sheet对象的第一行
            XSSFRow rowtitle = sheet.createRow(0);
            //根据入参keyValueList设置表头
            for (int i = 0; i < keyValueList.size(); i++) { // set header title
                XSSFCell cell = rowtitle.createCell(i);
                cell.setCellValue(keyValueList.get(i).getValue());
            }
            //从第二行开始按照表头创建行对象
            for (int i = 1; i <= listMaps.size(); i++) { // set value
                Map map = listMaps.get(i - 1);
                XSSFRow rowValue = sheet.createRow(i);
                for (int j = 0; j < keyValueList.size(); j++) {
                    KeyValue keyValue = keyValueList.get(j);
                    XSSFCell cell = rowValue.createCell(j);
                    cell.setCellValue((map.get(keyValue.getKey()) != null) ? map.get(
                        keyValue.getKey()).toString() : "");
                    
                }
            }
            //写入输出流对象，导出
            wb.write(os);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }finally {
            try {
                wb.close();
                os.close();
            } catch (IOException ie) {
                ie.printStackTrace();
            }catch (Exception e2) {
                // TODO: handle exception
                e2.printStackTrace();
            }
        }
    }

最后前台就可以下载导出的文件
