Java:如何从servlet上传文件到WebDAV服务器？

Question

我的ajax应用程序从用户的浏览器将文件上传到Java应用程序容器.我想做的是:一旦上传完成,我想把文件"发送"到WebDAV服务器,由主机名(即localhost),端口(即8080)和我想要的位置标识存储文件(即dir1/dir2).

我所追求的基本上是一个WebDAV客户端框架,使我能够将文件上传到WebDAV.在我的应用程序中,我已经在使用"webdavclient4j",但我似乎找不到用它上传文件的方法？

有任何想法吗？提前感谢您提供的任何帮助.

Answer 1

你可以使用我最近发布的,易于使用的现代webdav客户端java,Sardine,只使用几行代码.这是一些例子(第一个使用commons-io来读取文件):

Sardine sardine = SardineFactory.begin("username", "password");
byte[] data = FileUtils.readFileToByteArray(new File("/file/on/disk"));
sardine.put("http://yourdavserver.com/adirectory/nameOfFile.jpg", data);

或使用流:

Sardine sardine = SardineFactory.begin("username", "password");
InputStream fis = new FileInputStream(new File("/some/file/on/disk.txt"));
sardine.put("http://yourdavserver.com/adirectory/nameOfFile.jpg", fis);

您可以使用Jackrabbit WebDAV库.

将内容上载到WebDAV服务器的WebDAV客户端示例(取自此处):

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.net.URL;
import org.apache.commons.httpclient.Credentials;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.UsernamePasswordCredentials;
import org.apache.commons.httpclient.auth.AuthScope;
import org.apache.commons.httpclient.methods.InputStreamRequestEntity;
import org.apache.commons.httpclient.methods.RequestEntity;
import org.apache.jackrabbit.webdav.client.methods.PutMethod;

...

// WebDAV URL:
final String baseUrl = ...;
// Source file to upload:
File f = ...;
try{
    HttpClient client = new HttpClient();
    Credentials creds = new UsernamePasswordCredentials("username", "password");
    client.getState().setCredentials(AuthScope.ANY, creds);

    PutMethod method = new PutMethod(baseUrl + "/" + f.getName());
    RequestEntity requestEntity = new InputStreamRequestEntity(
        new FileInputStream(f));
    method.setRequestEntity(requestEntity);
    client.executeMethod(method);
    System.out.println(method.getStatusCode() + " " + method.getStatusText());
}
catch(HttpException ex){
    // Handle Exception
}
catch(IOException ex){
    // Handle Exception
}
