  • java 通过 SmbFile 类操作共享文件夹

    添加依赖

    在pom.xml文件夹中添加如下的依赖就可以引用SmbFile类的jar包。

    <dependency>
           <groupId>jcifs</groupId>
           <artifactId>jcifs</artifactId>
           <version>1.3.17</version>
    </dependency>

    读取文件

    /**
      * 读取共享文件夹下的所有文件(文件夹)的名称
      * @param remoteUrl
      */
    public static void getSharedFileList(String remoteUrl) {
        SmbFile smbFile;
        try {
            // smb://userName:passWord@host/path/
            smbFile = new SmbFile(remoteUrl);
            if (!smbFile.exists()) {
                System.out.println("no such folder");
            } else {
                SmbFile[] files = smbFile.listFiles();
                for (SmbFile f : files) {
                    System.out.println(f.getName());
                }
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (SmbException e) {
            e.printStackTrace();
        }
    }

    创建文件夹

    /**

     */
    public static void smbMkDir(String remoteUrl, String folderName) {

        try {
            // smb://userName:passWord@host/path/folderName
            smbFile = new SmbFile(remoteUrl + folderName);
            if (!smbFile.exists()) {
                smbFile.mkdir();
