第一步、导入依赖

org.apache.poi

poi

3.9

org.apache.poi

poi-examples

3.9

org.apache.poi

poi-excelant

3.9

org.apache.poi

poi-ooxml

3.9

org.apache.poi

poi-ooxml-schemas

3.9

org.apache.poi

poi-scratchpad

3.9

第二步，编写实体类

public class Zhi \{

private String url; //地址

private String Requestbody; //请求体

private String Responsebody; //响应体

@Override

public String toString() \{

return "Zhi\{" +

"url='" + url + '\\'' +

", Requestbody='" + Requestbody + '\\'' +

", Responsebody='" + Responsebody + '\\'' +

'\}';

public String getUrl() \{

return url;

public void setUrl(String url) \{

this.url = url;

public String getRequestbody() \{

return Requestbody;

public void setRequestbody(String requestbody) \{

Requestbody = requestbody;

public String getResponsebody() \{

return Responsebody;

public void setResponsebody(String responsebody) \{

Responsebody = responsebody;

第三步、编写表格生成工具

import org.apache.poi.hssf.usermodel.HSSFCell;

import org.apache.poi.hssf.usermodel.HSSFCellStyle;

import org.apache.poi.hssf.usermodel.HSSFRow;

import org.apache.poi.hssf.usermodel.HSSFSheet;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;

public class ExcelUtil \{

/\*\*

\* 导出Excel

\* @param sheetName sheet名称

\* @param title 标题

\* @param values 内容

\* @param wb HSSFWorkbook对象

\* @return

\*/

public static HSSFWorkbook getHSSFWorkbook(String sheetName,String \[\]title,String \[\]\[\]values, HSSFWorkbook wb)\{

// 第一步，创建一个HSSFWorkbook，对应一个Excel文件

if(wb == null)\{

wb = new HSSFWorkbook();

// 第二步，在workbook中添加一个sheet,对应Excel文件中的sheet

HSSFSheet sheet = wb.createSheet(sheetName);

// 第三步，在sheet中添加表头第0行,注意老版本poi对Excel的行数列数有限制

HSSFRow row = sheet.createRow(0);

// 第四步，创建单元格，并设置值表头 设置表头居中

HSSFCellStyle style = wb.createCellStyle();

style.setAlignment(HSSFCellStyle.ALIGN\_CENTER); // 创建一个居中格式

//声明列对象

HSSFCell cell = null;

//创建标题

for(int i=0;i

cell = row.createCell(i);

cell.setCellValue(title\[i\]);

cell.setCellStyle(style);

//创建内容

for(int i=0;i

row = sheet.createRow(i + 1);

for(int j=0;j

//将内容按顺序赋给对应的列对象

row.createCell(j).setCellValue(values\[i\]\[j\]);

return wb;

第四步、编写controller层

import cn.kgc.pojo.Account;

import cn.kgc.pojo.Zhi;

import cn.kgc.service.impl.ExcelUtil;

import cn.kgc.service.impl.SalaryServiceImpl;

import org.apache.poi.hssf.usermodel.HSSFWorkbook;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import javax.annotation.Resource;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.jsp.tagext.PageData;

import java.io.OutputStream;

import java.io.UnsupportedEncodingException;

import java.util.ArrayList;

import java.util.List;

import java.util.Random;

@Controller

@RequestMapping(value = "/report")

public class ReportFormController\{

//@Resource(name = "reportService")

//private ReportManager reportService;

@Resource(name = "aoo")

SalaryServiceImpl salaryService;

/\*\*

\* 导出报表

\* @return

\*/

@RequestMapping(value = "/export")

@ResponseBody

public void export(HttpServletRequest request, HttpServletResponse response) throws Exception \{

//获取数据

List list = new ArrayList();

Zhi zhi=null;

/\*生成随机数\*/

Random random = new Random();

for(int i=0;i<100;i++)\{

int a = (int)(random.nextInt(900))+100;

zhi=new Zhi();

zhi.setUrl("/NGCRMPF\_GS\_CGSHQGETFULLUSRINFO\_POST");

zhi.setRequestbody("\{\\"params\\":\{\\"object\\":\\"ServiceNo:13919892"+a+"\\"\}\}");

zhi.setResponsebody("\{\\"rtnCode\\":\\"0\\",\\"rtnMsg\\":\\"成功!\\",\\"bean\\":\{\},\\"beans\\":\[\],\\"object\\":\\"0~success~0~75~0~正常~01~58元新飞享套餐~1~0931\\"\}");

list.add(zhi);

//excel标题

String\[\] title = \{"请求地址","请求体","响应体"\};

//excel文件名

String fileName = "学生信息表"+System.currentTimeMillis()+".xls";

//sheet名

String sheetName = "学生信息表";

String \[\]\[\] content = new String\[list.size()\]\[\];

for (int i = 0; i < list.size(); i++) \{

content\[i\] = new String\[title.length\];

Zhi obj = list.get(i);

content\[i\]\[0\] = obj.getUrl()+"";

content\[i\]\[1\] = obj.getRequestbody()+"";

content\[i\]\[2\] = obj.getResponsebody()+"";

//创建HSSFWorkbook

HSSFWorkbook wb = ExcelUtil.getHSSFWorkbook(sheetName, title, content, null);

//响应到客户端

try \{

this.setResponseHeader(response, fileName);

OutputStream os = response.getOutputStream();

wb.write(os);

os.flush();

os.close();

\} catch (Exception e) \{

e.printStackTrace();

//发送响应流方法

public void setResponseHeader(HttpServletResponse response, String fileName) \{

try \{

fileName = new String(fileName.getBytes(),"ISO8859-1");

\} catch (UnsupportedEncodingException e) \{

// TODO Auto-generated catch block

e.printStackTrace();

response.setContentType("application/octet-stream;charset=ISO8859-1");

response.setHeader("Content-Disposition", "attachment;filename="+ fileName);

response.addHeader("Pargam", "no-cache");

response.addHeader("Cache-Control", "no-cache");

\} catch (Exception ex) \{

ex.printStackTrace();

第五步 编写jsp部分 调用一下即可
