❸ python3前端传递的pdf文件对象如何存储到服务器的指定目录
1.前端页面
<form action="/upload" method="post" enctype="multipart/form-data">
文件：<input type="file" name="testUpload"/>
<input type="submit" />
</form>
2.java代码
@RequestMapping(value = "upload")
@ResponseBody
public String upload(@RequestParam("testUpload") MultipartFile file) {
if (file.isEmpty()) {
return "文件为空";
}
// 获取文件名
String fileName = file.getOriginalFilename();
System.out.println("上传的文件名为：" + fileName);
// 获取文件的后缀名
String suffixName = fileName.substring(fileName.lastIndexOf("."));
System.out.println("上传的后缀名为：" + suffixName);
// 文件上传后的路径
String filePath = "E://test//";
File dest = new File(filePath + fileName);
// 检测是否存在目录
if (!dest.getParentFile().exists()) {
dest.getParentFile().mkdirs();
}
try {
file.transferTo(dest);
return "上传成功";
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
