如何将 JCIFS 与 apache VFS 结合使用来访问 SMB URL - 第 2 部分?

How do I use JCIFS with apache VFS to access an SMB URL - part 2?

我遇到了同样的问题: How do I use JCIFS with apache VFS to access an SMB URL?

...在类路径中包含 commons-vfs-sandbox-2.1-SNAPSHOT.jar 之后我现在得到这个异常:

请指教

我想我知道你的问题是什么,沙箱提供者在 2.0 中没有自动注册。而且您还需要在解析调用中实际使用配置的身份验证属性(请参阅下面修改后的源代码)。

我通常不使用默认的文件系统管理器,而是动态注册我的提供程序,但如果你想使用自动检测,你需要将 vfs-providers.xml 添加到沙箱 JAR。

这就是使用 2.0 构建完整工作 JAR 的方式:

> git clone https://github.com/apache/commons-vfs.git -b commons-vfs2-project-2.0 vfs2.0
> cd vfs2.0
> notepad sandbox\pom.xml
> notepad sandbox\src\test\java\org\apache\commons\vfs2\provider\smb\test\StandaloneMain.java
> mvn -Pinclude-sandbox -DskipTests=true clean package dependency:tree

当您编辑 sandbox/pom.xml 时,您需要确保从 标签中删除 -SANDBOX。然后你需要添加:

  <resource>
    <directory>src/main/resources</directory>
  </resource>

到已经存在的 标签(在第一个 LICENSE+NOTICE 包含第 88 行之后)

这是使用的测试代码:

package org.apache.commons.vfs2.provider.smb.test;

import org.apache.commons.vfs2.FileObject;
import org.apache.commons.vfs2.FileSystemException;
import org.apache.commons.vfs2.FileSystemManager;
import org.apache.commons.vfs2.FileSystemOptions;
import org.apache.commons.vfs2.VFS;
import org.apache.commons.vfs2.auth.StaticUserAuthenticator;
import org.apache.commons.vfs2.impl.DefaultFileSystemConfigBuilder;


public class StandaloneMain
{
    public static void main(String[] args) throws FileSystemException {
        //jcifs.Config.registerSmbURLHandler();
        StaticUserAuthenticator auth = new StaticUserAuthenticator("DOMAIN", "eckenfel", "SECRET");
        FileSystemOptions opts = new FileSystemOptions();
        DefaultFileSystemConfigBuilder.getInstance().setUserAuthenticator(opts, auth);
        FileSystemManager fs = VFS.getManager();
        if (!fs.hasProvider("smb")) throw new RuntimeException("Provide missing");
        System.out.println("Connecting " + args[0] + " with " + opts);
        FileObject smbFile = fs.resolveFile(args[0], opts); // added opts!
        System.out.println(smbFile.exists() + " " + smbFile.getContent().getLastModifiedTime());
    }
}

这是执行:
