springboot多线程文件上传

可以使用Java的多线程技术来实现文件上传。以下是一个基于SpringBoot的多线程文件上传的示例代码:
```java
@RestController
public class FileUploadController {
@PostMapping("/upload")
public ResponseEntity<String> uploadFile(@RequestParam("file") MultipartFile file) {
String fileName = StringUtils.cleanPath(file.getOriginalFilename());
try {
// Create a new thread to upload the file
Thread thread = new Thread(new FileUploadTask(file, fileName));
thread.start();
} catch (Exception e) {
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("Error occurred while uploading file.");
}
return ResponseEntity.ok().body("File uploaded successfully.");
}
private class FileUploadTask implements Runnable {
private MultipartFile file;
private String fileName;
public FileUploadTask(MultipartFile file, String fileName) {
this.file = file;
this.fileName = fileName;
}
@Override
public void run() {
// Upload the file using multipart file
RestTemplate restTemplate = new RestTemplate();
String url = "http://example.com/upload";
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
MultiValueMap<String, Object> body = new LinkedMultiValueMap<>();
ByteArrayResource resource = null;
try {
resource = new ByteArrayResource(file.getBytes()) {
@Override
public String getFilename() {
return fileName;
}
};
} catch (IOException e) {
e.printStackTrace();
}
body.add("file", resource);
HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(body, headers);
ResponseEntity<String> responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, String.class);
}
}
}
```
在这个示例代码中,我们使用了Java中的`Thread`类来创建一个新的线程来处理文件上传。`FileUploadTask`类实现了`Runnable`接口,并在`run()`方法中执行文件上传操作。在`uploadFile()`方法中,我们创建了一个新的线程,并将`FileUploadTask`实例作为参数传递给线程的构造函数。最后,我们调用线程的`start()`方法来启动线程。
注意,这个示例代码中使用了`RestTemplate`类来执行文件上传操作。你需要根据你的实际需求来选择合适的文件上传方式。同时,为了保证上传的文件名不会被篡改,我们重写了`ByteArrayResource`类中的`getFilename()`方法来返回原始文件名。
