springboot实现上传文件时校验文件是否有病毒
在Spring Boot中实现文件上传时检查文件是否包含病毒,可以使用集成第三方病毒扫描服务。以ClamAV(一个免费的,开源的病毒扫描引擎)为例,可以通过clamd
客户端库来实现。
首先,需要在你的Spring Boot项目中添加依赖:
<dependency>
<groupId>org.clamshellproject</groupId>
<artifactId>clamd-client</artifactId>
<version>1.8.1</version>
</dependency>
然后,你可以创建一个服务来处理文件上传和病毒检查:
import org.clamshellproject.clamd.Client;
import org.clamshellproject.clamd.CommunicationException;
import org.clamshellproject.clamd.ScanResult;
import org.springframework.web.multipart.MultipartFile;
import java.io.IOException;
import java.net.InetAddress;
import java.net.UnknownHostException;
public class VirusScanService {
private final Client clamdClient;
public VirusScanService(String clamdHost, int clamdPort) throws UnknownHostException {
clamdClient = new Client(InetAddress.getByName(clamdHost), clamdPort);
}
public boolean isVirus(MultipartFile file) {
try {
ScanResult result = clamdClient.scan(file.getInputStream());
return result.isInfected();
} catch (IOException | CommunicationException e) {
e.printStackTrace();
return false;
}
}
}
在上述代码中,clamdHost
和clamdPort
是运行ClamAV的服务器地址和端口。isVirus
方法接受一个MultipartFile
对象,并使用clamdClient
对其进行扫描。如果文件被感染,ScanResult.isInfected()
将返回true
。
在你的控制器中,你可以这样使用VirusScanService
:
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.http.ResponseEntity;
public class FileUploadController {
private final VirusScanService virusScanService;
public FileUploadController(VirusScanService virusScanService) {
this.virusScanService = virusScanService;
}
@PostMapping("/upload")
public ResponseEntity<?> handleFileUpload(@RequestParam("file") MultipartFile file) {
if (virusScanService.isVirus(file)) {
return ResponseEntity.badRequest().body("File contains a virus");
}
// 处理文件上传
// ...
return ResponseEntity.ok("File uploaded successfully");
}
}
确保ClamAV服务已经安装并运行在你指定
