07，SpringMVC项目导出wps表格文件

　　（1），后台java代码响应xls表格文件到客户端 import org.apache.poi.xssf.usermodel.XSSFWorkbook; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.*; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.OutputStream; import java.net.URLEncoder; /** * @date: 2022/11/5 23:14 * @desc: 测试控制类 */ @Controller @RequestMapping(value = ＂/studentConter＂) public class StudentController {     @RequestMapping(value = ＂/exportExcelFile＂)     public void exportExcelFile(HttpServletRequest request             , HttpServletResponse response ) {         response.setContentType(＂application/vnd.ms-excel＂);         String fileName = ＂＂;         OutputStream outputStream;         try {             fileName = URLEncoder.encode(＂导出文件名称1＂, ＂UTF-8＂);             response.setHeader(＂content-disposition＂, ＂attachment;filename=＂+ fileName + ＂.xls＂);             XSSFWorkbook xssfWorkbook = writeTextWorkbook();             outputStream = response.getOutputStream();             xssfWorkbook.write(outputStream);             outputStream.flush();             outputStream.close();         } catch (Exception ex1) {             ex1.printStackTrace();         }     }      // 把内容写入表格文件中     private XSSFWorkbook writeTextWorkbook() {         XSSFWorkbook xssfWorkbook = new XSSFWorkbook();         XSSFSheet xssfSheet = xssfWorkbook.createSheet();         // 在工作薄第一行填充数据         XSSFRow xssfRow = xssfSheet.createRow(0);         XSSFCell xssfCellIdx0 = xssfRow.createCell(0);         xssfCellIdx0.setCellValue(＂第一行第一个单元格内容＂);         XSSFCell xssfCellIdx1 = xssfRow.createCell(1);         xssfCellIdx1.setCellValue(＂第一行第二个单元格内容＂);         return xssfWorkbook;     }  }
　　（2），jar包依赖参考上一篇： 06，SpringMVC项目导入wps表格文件
