Java 对远程文件的操作

时间:2022-02-19 15:42:36

首先添加jar

              <dependency>
<groupId>jcifs</groupId>
<artifactId>jcifs</artifactId>
<version>1.3.17</version>
</dependency>
<dependency>
<groupId>com.jcraft</groupId>
<artifactId>jsch</artifactId>
<version>0.1.54</version>
</dependency>

第一个肯定是要的,第二个最好也配置下。

下面来看代码,和一些方法示例

conStr = "smb://"+account+":"+password+"@"+remoteHostIp+"/"+shareDocName+"/"+remoteFileName;  

	public InputStream getFile(String path) throws IOException {
SmbFile smbFile = new SmbFile(fileRoot+path);
return smbFile.getInputStream();
} public static void smbGet1(String remoteUrl) throws IOException {
SmbFile smbFile = new SmbFile(remoteUrl);
int length = smbFile.getContentLength(); // 得到文件的大小
byte buffer[] = new byte [length];
SmbFileInputStream in = new SmbFileInputStream(smbFile);
// 建立smb文件输入流
while ((in.read(buffer)) != - 1 ) { System.out.write(buffer);
System.out.println(buffer.length);
}
in.close();
} // @Async
public static List<AttachmentPO> getAttachmentFiles(String remoteDirectory)
{
List<AttachmentPO> attachmentPOs = new ArrayList<AttachmentPO>();
try {
SmbFile file = new SmbFile(fileRoot + remoteDirectory);
String[] files = file.list();
for(String name : files){
AttachmentPO AttachmentPO = new AttachmentPO();
AttachmentPO.setName(name);
AttachmentPO.setFile_path(remoteDirectory + name);
AttachmentPO.setRef_type(WikiConsts.ATTACHMENT_TYPE_DOWNLOAD);
attachmentPOs.add(AttachmentPO);
} } catch (MalformedURLException e) {
logger.error("get SmbFile by directory return wrong, the remoteDirectory is" + remoteDirectory);
} catch (SmbException e) {
logger.error("get SmbFiles under directory return wrong, the remoteDirectory is" + remoteDirectory);
}
return attachmentPOs;
}

上面最重要的就是要把路径那些设置对,其它的都很简单,根据包的方法操作就行。

这边的远程文件是放在window系统中的,且是设置好的。我们通过smb://account:password @ 这样来操作。
