Java 对远程文件的操作

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。
