本地上传图片到服务器上工具类

1、工具jar包依赖

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

2、代码如下

package com.zbb.util;

import java.io.FileInputStream;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.UnknownHostException;

import org.springframework.web.multipart.MultipartFile;

import jcifs.smb.SmbException;
import jcifs.smb.SmbFile;

*
*/

/**
* 得到SMB和连接的方法
* @param url
* @return
*/

}

}

}catch (MalformedURLException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
}

*/
public int uploadFile(File file) {
int flag = -1;
