在用流下载pdf的时候易出现中文名称乱码的问题，这里做一个记录
代码语言：javascript复制 @GetMapping("downloadPdf")
@ApiOperation("下载pdf文件测试")
public ResponseBean downloadPdf( HttpServletRequest request, HttpServletResponse response) throws Exception {
response.setCharacterEncoding("UTF-8");
String pdfPath = "D:\test.pdf";
String fileName = "test.pdf";
File file = new File(pdfPath);
InputStream in = new FileInputStream(file);
response.setContentType("application/pdf");
response.setHeader("Content-disposition", "attachment;filename=" new String(fileName.getBytes("utf-8"),"ISO8859-1"));
OutputStream ouputStream = response.getOutputStream();
if(！file.exists()){
return ResponseBean.error("未找到文件,请先生成");
}
IOUtils.copy(in,ouputStream);
return new ResponseBean(ResponseCodeEnum.SUCCESS.getCode(), "下载成功");
}中文乱码的设置： response.setHeader("Content-disposition", "attachment;filename=" new String(fileName.getBytes("utf-8"),"ISO8859-1"));
这里使用IOUtils同时需要引入一个jar包
代码语言：javascript复制 <dependency>
<groupId>commons-io</groupId>
<artifactId>commons-io</artifactId>
<version>2.4</version>
</dependency>下载excel(需引入poi的jar包)
代码语言：javascript复制 public void exportExcel(HttpServletResponse response,@RequestParam(value = "mntOrgName",required = false) String mntOrgName ) throws IOException {
response.setCharacterEncoding("UTF-8");
mntOrgName = mntOrgName == null ? null : mntOrgName.trim();
List<MntOrg> list = mntTeamOrgService.searchAll(mntOrgName);
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("测试信息表");
HSSFRow titleRow = sheet.createRow(0);
// 设置单元格的宽度
for (int i = 0; i < 4; i ) {
sheet.setColumnWidth(i, 9000);
}
titleRow.createCell(0).setCellValue("名称");
titleRow.createCell(1).setCellValue("电话");
titleRow.createCell(2).setCellValue("传真");
// titleRow.createCell(4).setCellValue("描述");
for (MntOrg mntOrg : list) {
HSSFRow dataRow = sheet.createRow(sheet.getLastRowNum() 1);
dataRow.createCell(0).setCellValue(mntOrg.getMntOrgName());
dataRow.createCell(1).setCellValue(mntOrg.getContactNo());
dataRow.createCell(2).setCellValue(mntOrg.getFax());
}
String filename = DateUtil.getNowDate() ".xls";
response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-disposition", "attachment;filename=" filename);
OutputStream ouputStream = response.getOutputStream();
wb.write(ouputStream);
ouputStream.flush();
ouputStream.close();
}
