项目用的是springboot框架，非常的简单，只需导入项目即可运行，先看看效果：

具体步骤如下：

1、引入依赖jar包。

在pom.xml中引入两个依赖的包即可：

<!-- https://mvnrepository.com/artifact/org.apache.poi/poi -->
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi</artifactId>
<version>3.17</version>
</dependency>
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.17</version>
</dependency>

2、把需要导出的Excel模板放在webapp下的excel文件夹中。

如下目录，建立两个Excel一个2003的，一个2007的，user_model.xls、user_model.xlsx。



其中Excel需要导出的内容格式如下：

3、导出代码实现。

废话少说，直接上代码，拿来就用。

导出Excel2003：

@RequestMapping(value = "/export2003.do", method = RequestMethod.GET)
public void export2003(HttpServletRequest request, HttpServletResponse response) {
List<User> list = new ArrayList<User>();
User user1 = new User();
user1.setId(100000000L);
user1.setUsername("张三");
user1.setHead("http://qzapp.qlogo.cn/qzapp/101357640/3C94155CAB4E28517D8435BF404B52F1/100");
user1.setSex(0);
user1.setPhone("18800000000");
User user2 = new User();
user2.setId(100000001L);
user2.setUsername("李四");
user2.setHead("http://q.qlogo.cn/qqapp/1105676675/9DA6D356F4FE1DF0E63BD07334680BF2/100");
user2.setSex(0);
user2.setPhone("18800000001");
list.add(user1);
list.add(user2);

HSSFWorkbook wb = null;
try {
// excel模板路径
String basePath = request.getSession().getServletContext().getRealPath("/");
String excel = basePath + "/excel/user_model.xls";
File fi = new File(excel);
POIFSFileSystem fs = new POIFSFileSystem(new FileInputStream(fi));
// 读取excel模板
wb = new HSSFWorkbook(fs);
// 读取了模板内所有sheet内容
HSSFSheet sheet = wb.getSheetAt(0);
// 在相应的单元格进行赋值
int rowIndex = 1;
for (User user : list) {
HSSFRow row = sheet.getRow(rowIndex);
if (null == row) {
row = sheet.createRow(rowIndex);
}
HSSFCell cell0 = row.getCell(0);
if (null == cell0) {
cell0 = row.createCell(0);
}
cell0.setCellValue(user.getId());// 标识

HSSFCell cell1 = row.getCell(1);
if (null == cell1) {
cell1 = row.createCell(1);
}
cell1.setCellValue(user.getUsername());// 用户名

HSSFCell cell2 = row.getCell(2);
if (null == cell2) {
cell2 = row.createCell(2);
}
cell2.setCellValue(user.getHead());// 头像

HSSFCell cell3 = row.getCell(3);
if (null == cell3) {
cell3 = row.createCell(3);
}
cell3.setCellValue(user.getSex() == 0 ? "女" : "男");// 性别

HSSFCell cell4 = row.getCell(4);
if (null == cell4) {
cell4 = row.createCell(4);
}
cell4.setCellValue(user.getPhone());// 手机
rowIndex++;
}

String fileName = "用户信息";
ByteArrayOutputStream os = new ByteArrayOutputStream();
wb.write(os);
byte[] content = os.toByteArray();
InputStream is = new ByteArrayInputStream(content);
// 设置response参数，可以打开下载页面
response.reset();
response.setContentType("application/vnd.ms-excel;charset=utf-8");
response.setHeader("Content-Disposition", "attachment;filename=" + new String((fileName + ".xls").getBytes(), "iso-8859-1"));
ServletOutputStream sout = response.getOutputStream();
BufferedInputStream bis = null;
BufferedOutputStream bos = null;

try {
bis = new BufferedInputStream(is);
bos = new BufferedOutputStream(sout);
byte[] buff = new byte[2048];
int bytesRead;
// Simple read/write loop.
while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff, 0, bytesRead);
}
} catch (Exception e) {
logger.error("导出excel出现异常:", e);
} finally {
if (bis != null)
bis.close();
if (bos != null)
bos.close();
}

} catch (Exception e) {
logger.error("导出excel出现异常:", e);
}

}

导出Excel2007：

@RequestMapping(value = "/export2007.do", method = RequestMethod.GET)
public void export2007(HttpServletRequest request, HttpServletResponse response) {
List<User> list = new ArrayList<User>();
User user1 = new User();
user1.setId(100000000L);
user1.setUsername("张三");
user1.setHead("http://qzapp.qlogo.cn/qzapp/101357640/3C94155CAB4E28517D8435BF404B52F1/100");
user1.setSex(0);
user1.setPhone("18800000000");
User user2 = new User();
user2.setId(100000001L);
user2.setUsername("李四");
user2.setHead("http://q.qlogo.cn/qqapp/1105676675/9DA6D356F4FE1DF0E63BD07334680BF2/100");
user2.setSex(0);
user2.setPhone("18800000001");
list.add(user1);
list.add(user2);

XSSFWorkbook wb = null;
try {
// excel模板路径
String basePath = request.getSession().getServletContext().getRealPath("/");
String excel = basePath + "/excel/user_model.xlsx";
File fi = new File(excel);
// 读取excel模板
wb = new XSSFWorkbook(new FileInputStream(fi));
// 读取了模板内所有sheet内容
XSSFSheet sheet = wb.getSheetAt(0);
// 在相应的单元格进行赋值
int rowIndex = 1;
int j = 1;
for (User user : list) {
XSSFRow row = sheet.getRow(rowIndex);
if (null == row) {
row = sheet.createRow(rowIndex);
}
XSSFCell cell0 = row.getCell(0);
if (null == cell0) {
cell0 = row.createCell(0);
}
cell0.setCellValue(user.getId());// 标识

XSSFCell cell1 = row.getCell(1);
if (null == cell1) {
cell1 = row.createCell(1);
}
cell1.setCellValue(user.getUsername());// 用户名

XSSFCell cell2 = row.getCell(2);
if (null == cell2) {
cell2 = row.createCell(2);
}
cell2.setCellValue(user.getHead());// 头像

XSSFCell cell3 = row.getCell(3);
if (null == cell3) {
cell3 = row.createCell(3);
}
cell3.setCellValue(user.getSex() == 0 ? "女" : "男");// 性别

XSSFCell cell4 = row.getCell(4);
if (null == cell4) {
cell4 = row.createCell(4);
}
cell4.setCellValue(user.getPhone());// 手机
rowIndex++;
}

String fileName = "用户信息";
ByteArrayOutputStream os = new ByteArrayOutputStream();
wb.write(os);
byte[] content = os.toByteArray();
InputStream is = new ByteArrayInputStream(content);
// 设置response参数，可以打开下载页面
response.reset();
response.setContentType("application/vnd.ms-excel;charset=utf-8");
response.setHeader("Content-Disposition", "attachment;filename=" + new String((fileName + ".xlsx").getBytes(), "iso-8859-1"));
ServletOutputStream sout = response.getOutputStream();
BufferedInputStream bis = null;
BufferedOutputStream bos = null;

try {
bis = new BufferedInputStream(is);
bos = new BufferedOutputStream(sout);
byte[] buff = new byte[2048];
int bytesRead;
// Simple read/write loop.
while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff, 0, bytesRead);
}
} catch (Exception e) {
logger.error("导出excel出现异常:", e);
} finally {
if (bis != null)
bis.close();
if (bos != null)
bos.close();
}

} catch (Exception e) {
logger.error("导出excel出现异常:", e);
}

}

导出的结果如下：



导出成功！
