1、服務器指定共享文件夾
1.1、驗證服務器共享文件夾本地可以訪問:
2、導入依賴的相關jar包 jcifs-1.3.**.jar:
<dependency> <groupId>jcifs</groupId> <artifactId>jcifs</artifactId> <version>1.3.17</version> </dependency>
3.創建java類:SmbUtil
並粘貼下面的代碼:
import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.net.MalformedURLException; import java.net.UnknownHostException; import jcifs.smb.SmbException; import jcifs.smb.SmbFile; import jcifs.smb.SmbFileOutputStream; public class SmbUtil { // 1. 聲明屬性 private String url = "smb://userName:password@192.168.2.153/mars/"; private SmbFile smbFile = null; private SmbFileOutputStream smbOut = null; private static SmbUtil smbUtil = null; // 共享文件協議 private SmbUtil(String url) { this.url = url; this.init(); } // 2. 得到SmbUtil和連接的方法 public static synchronized SmbUtil getInstance(String url) { if (smbUtil == null) return new SmbUtil(url); return smbUtil; } // 3.smbFile連接 public void init() { try { System.out.println("開始連接...url:" + this.url); smbFile = new SmbFile(this.url); smbFile.connect(); System.out.println("連接成功...url:" + this.url); } catch (MalformedURLException e) { e.printStackTrace(); System.out.print(e); } catch (IOException e) { e.printStackTrace(); System.out.print(e); } } // 4.上傳文件到服務器 public int uploadFile(File file) { int flag = -1; BufferedInputStream bf = null; try { this.smbOut = new SmbFileOutputStream(this.url + "/" + file.getName(), false); bf = new BufferedInputStream(new FileInputStream(file)); byte[] bt = new byte[8192]; int n = bf.read(bt); while (n != -1) { this.smbOut.write(bt, 0, n); this.smbOut.flush(); n = bf.read(bt); } flag = 0; System.out.println("文件傳輸結束..."); } catch (SmbException e) { e.printStackTrace(); System.out.println(e); } catch (MalformedURLException e) { e.printStackTrace(); System.out.println(e); } catch (UnknownHostException e) { e.printStackTrace(); System.out.println("找不到主機...url:" + this.url); } catch (IOException e) { e.printStackTrace(); System.out.println(e); } finally { try { if (null != this.smbOut) this.smbOut.close(); if (null != bf) bf.close(); } catch (Exception e2) { e2.printStackTrace(); } } return flag; } // 5. 在main方法里面測試 public static void main(String[] args) { // 服務器地址 格式為 smb://電腦用戶名:電腦密碼@電腦IP地址/IP共享的文件夾 String remoteUrl = "smb://administrator:123456@10.8.66.22/mars/"; String localFile = "C:\\Users\\Administrator\\Desktop\\***.txt"; // 本地要上傳的文件 File file = new File(localFile); SmbUtil smb = SmbUtil.getInstance(remoteUrl); smb.uploadFile(file);// 上傳文件 } }
