思路 ：

1. 将需要导出的数据存放在一个List中
2. 创建一个EXCEL表 注意 XSSFWorkbook 只能操作2007以上的版本，XSSFWorkbook 只能操作2003一下的版本，所以需要的时候可以使用 Workbook创建对象处理兼容性
3. 遍历List 并将每条数据 写入 EXCEL表中

具体代码如下 ：

html 页面

<button onClick="download()">导出</button>

js 页面

function download() {$.messager.confirm('确认', '确认把该搜索结果导出Excel表格 ？', function(r) {if (r) {$.messager.progress({title : '处理中',msg : '请稍后',});$.messager.progress('close');$.ajax({url : 'download.html',//后台方法名字type : 'POST',data : {  //传入后台的参数，从页面获取},success : function(data) {//加载成功后的操作}});}});
}

后台代码

Model类 Student

public class Student {private String name;private int age;private String address;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getAddress() {return address;}public void setAddress(String address) {this.address = address;}}

处理逻辑，实现功能的类中代码

@RequestMapping(value = "/download.html", method = RequestMethod.POST)public void download(HttpServletRequest request,HttpServletResponse response) {// TODO Auto-generated method stubList<Student> list = new ArrayList<Student>();//Student是被导出数据的类型，一般是自己写的Model类XSSFWorkbook excelbook = new XSSFWorkbook(); //创建workBookXSSFSheet excelSheet = excelbook.createSheet();//创建sheet表XSSFRow excelRow = excelSheet.createRow(0);//创建行XSSFCellStyle headerStyle = excelbook.createCellStyle();//设置 居中headerStyle.setAlignment(XSSFCellStyle.ALIGN_CENTER);//接下来是创建 列标题 ,cell的起始值是 0,可创建n个列标题  XSSFCell cell = excelRow.createCell(0);cell.setCellStyle(headerStyle);//居中cell.setCellValue("列标题 ");//接下来遍历List,并写入EXCEL中for(int i = 0; i < list.size(); i++){//创建行,行号应从1开始,因为表头行(列标题)占据了第0行excelRow = excelSheet.createRow(i + 1); Student t = list.get(i); // List 的起始值是0//将该行每一列的数据写入,可写n列cell = excelRow.createCell(0);cell.setCellValue(t.getName());}try {String filePath = "EXCEL表格导出路径.xls";writeExcel(response, excelbook, filePath, "文件名");//具体导出的方法} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}

具体实现导出EXCEL的方法

//具体导出的方法private static void writeExcel(HttpServletResponse response, Workbook work,String filePath, String fileName) throws IOException {OutputStream outputStream = new FileOutputStream(filePath);try {response.setContentType("application/ms-excel;charset=UTF-8");response.setHeader("Content-Disposition", "attachment;filename=".concat(String.valueOf(URLEncoder.encode(fileName + ".xls","UTF-8"))));work.write(outputStream);} catch (IOException e) {System.out.println("输出流错误");e.printStackTrace();} finally {outputStream.close();}}
