java使用ftpapi上传文件

maven需要导入的jar包

<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>2.2</version>
<scope>compile</scope>
</dependency>

代码如下

package lilong;


import java.io.File;
import java.io.FileInputStream;


import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPReply;




public class FtpClientTest {
private FTPClient ftp;

* @param addr
*            地址

*            端口号
* @param username
*            用户名
* @param password
*            密码
* @return
* @throws Exception
*/

throws Exception {

if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
return result;
}

result = true;
return result;
}
