是的，Artifactory支持部分文件上传。以下是Java语言中上传文件的示例代码，其中使用了Apache HttpClient库：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPut;
import org.apache.http.entity.InputStreamEntity;
import org.apache.http.impl.client.HttpClientBuilder;

public class ArtifactoryPartialUploadExample {

    private static final String ARTIFACTORY_URL = "http://localhost:8081/artifactory";
    private static final String REPO_KEY = "libs-release-local";
    private static final String ARTIFACT_PATH = "com/example/myproject/myartifact/1.0.0/myartifact-1.0.0.jar";

    public static void main(String[] args) throws IOException {
        HttpClient httpClient = HttpClientBuilder.create().build();
        HttpPut httpPut = new HttpPut(ARTIFACTORY_URL + "/" + REPO_KEY + "/" + ARTIFACT_PATH);
        File file = new File("myartifact-1.0.0.jar");
        long fileSize = file.length();
        FileInputStream fileInputStream = new FileInputStream(file);
        InputStreamEntity inputStreamEntity = new InputStreamEntity(fileInputStream, fileSize);
        httpPut.setEntity(inputStreamEntity);
        httpPut.setHeader("X-Checksum-Sha1", "7ce6a6ea35316a939e63cfba9ddc285127758e31");
        httpPut.setHeader("X-Checksum-Md5", "2f5ae5fb648c0cb75f24a05f9cbce5a1");
        httpPut.setHeader("X-Checksum-Sha256", "f2d8c9dbb78ef8ffcfd1b1a07fb4c3c"),
        HttpResponse response = httpClient.execute(httpPut);
        HttpEntity httpEntity = response.getEntity();
        if (httpEntity != null) {
            httpEntity.getContent().close();
        }
    }
}

在这个例子中，我们使用了InputStreamEntity来上传文件。可以看到，我们初始化了一个FileInputStream来读取文件的内容，然后设置到InputStreamEntity中。另外，我们
