springmvc + excel代

1.xml简介

	<!-- excel use start -->
	<bean class="org.springframework.web.servlet.view.BeanNameViewResolver">
		<property name="order" value="10"/>
	</bean>

	<bean id="viewExcel111" class="net.spring.controller.ViewExcel" />
	<!-- excel use end -->

2.controller

	@RequestMapping("excelAction")
	public String excelAction(Map<String, Object> map){

		// 传给ViewExcel的值
		map.put("p1", "hello");
		map.put("p2", "world");

		return "viewExcel111";
	}

3.ViewExcel

package net.spring.controller;

import java.util.Map;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.springframework.web.servlet.view.document.AbstractExcelView;

public class ViewExcel extends AbstractExcelView {

	@Override
	protected void buildExcelDocument(Map<String, Object> map,
			HSSFWorkbook workbook, HttpServletRequest arg2,
			HttpServletResponse response) throws Exception {

		String p1 = (String) map.get("p1");
		String p2 = (String) map.get("p2");

		// 设值文件名称:显示对话框提示用户下载或打开
		response.setHeader("Content-Disposition", "attachment;filename="
				+ new String("用户列表".getBytes(), "ISO-8859-1"));

		// sheet的名称
		HSSFSheet sheet = workbook.createSheet("testSheet");

		HSSFRow row = null;
		HSSFCell cell = null;

		// 行号
		int rowIndex = 0;
		// 列号
		int cellIndex = 0;

		// 通过sheet对象添加一行
		row = sheet.createRow(rowIndex++);
		// 通过row对象添加一列
		cell = row.createCell(cellIndex++);
		// 设值列的内容
		cell.setCellValue("第一列的内容");
		// 添加一列
		cell = row.createCell(cellIndex++);
		// 设值列的内容
		cell.setCellValue(p1);

		// 列号清零
		cellIndex = 0;
		// 添加一行
		row = sheet.createRow(rowIndex++);
		// 添加一列
		cell = row.createCell(cellIndex++);
		// 设值列的内容
		cell.setCellValue("第二列的内容");
		// 添加一列
		cell = row.createCell(cellIndex++);
		// 设值列的内容
		cell.setCellValue(p2);
	}

}
