当然可以,以下是一个简单的Java文件上传代码:
```java
import java.io.File;
import java.io.IOException;
import org.apache.commons.io.FileUtils;
import org.apache.commons.io.IOUtils;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
import org.apache.http.impl.client.HttpClientBuilder;
public class FileUploader {
public static void main(String[] args) throws IOException {
// 上传的文件
File file = new File("文件路径");
// 上传到的URL
String url = "上传的URL";
try (HttpClient client = HttpClientBuilder.create().build()) {
HttpPost post = new HttpPost(url);
// 构建上传内容
HttpEntity entity = MultipartEntityBuilder.create()
.addBinaryBody("file", file, ContentType.APPLICATION_OCTET_STREAM, file.getName())
.build();
// 设置上传内容到请求中
post.setEntity(entity);
// 发送请求
HttpResponse response = client.execute(post);
// 打印响应结果
String result = IOUtils.toString(response.getEntity().getContent(), "utf-8");
System.out.println(result);
}
}
}
```
