SpringMvc 中FTP上传数据
导入包Ftp包 commons-net-3.3.jar
直接例子：
Ftp工具类
package com.book.utils;
import java.io.IOException;
import java.io.InputStream;
import org.apache.commons.net.ftp.FTPClient;
import org.apache.commons.net.ftp.FTPReply;
public class ftpUtil {
// ("127.0.0.1", 21, "test", "test", "D:/ftp", "test.txt", innput)
public static boolean uploadFile(String url,int port,String username, String password, String path, String filename, InputStream input) {
boolean success = false;
FTPClient ftp = new FTPClient();
try {
int reply;
ftp.connect(url, port);//连接FTP服务器
//如果采用默认端口，可以使用ftp.connect(url)的方式直接连接FTP服务器
ftp.login(username, password);//登录
reply = ftp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
return success;
}
ftp.changeWorkingDirectory(path);
ftp.storeFile(filename, input);
input.close();
ftp.logout();
success = true;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (ftp.isConnected()) {
try {
ftp.disconnect();
} catch (IOException ioe) {
}
}
}
return success;
}
}
页面代码：
<body> <form action="shangc.do" id="soft_add" name="data_add" method="post" enctype="multipart/form-data"> <table width="60%" border="0" align="center" cellpadding="0" cellspacing="0" style="margin-top: 20px;margin-bottom: 15px;"> <tr><td align="center"><font size="3"><b> 数 据 文 件 入 库 </b></font></td></tr> <tr><td align="center"><FONT SIZE="" COLOR="red">*</FONT> <font size="2">为必填项</font></td></tr> </table> <table width="60%" border="0" align="center" cellpadding="0" cellspacing="0" class="borderquan"> <tr> <td width="20%" height="50" align="center" class="borderbottomright">数据文件</td> <td width="80%" class="borderbottom"><label> <input type="file" name="dataFile" id="dataFile" style="width: 310px;" onblur="checkDataFile();"/> <FONT SIZE="" COLOR="red" style="font-size: 12px">* </FONT> <span id="staError" style="font-size: 9pt; font-family: 黑体; color: red"></span> <FONT SIZE="" COLOR="red" style="font-size: 12px"><br />文件名格式如：2_v110.xml 下划线前是基站标识，下划线后是数据版本</FONT> </label></td> </tr> <tr> <td width="20%" height="30" align="center" class="borderbottomright">描述</td> <td width="80%" class="borderbottom"><label> <textarea name="descInfo" style="width: 310px;" rows="5"></textarea> </label></td> </tr> <tr> <td height="30" colspan="2" align="center"> <input type="submit" name="save" class="myBtn" value="保 存" onclick="submitForm();" /> <input type="button" name="backtrack" class="myBtn" value="返 回" onclick="goback();"/> </td> </tr> </table> <table width="99%" cellpadding="0" cellspacing="0" align="center" style="margin-top: 20px;"> <tr> <td align="center"><font color="red" style="font-size: 15px;"> <c:if test="${result!=null }"> ${result } </c:if> </font> </td> </tr> </table> </form> </body>
后台代码：
package com.book.action;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Random;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.multipart.MultipartFile;
import org.springframework.web.multipart.MultipartHttpServletRequest;
import com.book.utils.ftpUtil;
@Controller
public class Ceshiaction {
@RequestMapping("shangc")
public String UploadFile(HttpServletRequest request)throws IllegalStateException, IOException {
MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest)request;
// 获取上传的文件
MultipartFile multiFile = multipartRequest.getFile("dataFile");
//转为流
InputStream inputStream = multiFile.getInputStream();
//获取上传的全名
String originalFilename = multiFile.getOriginalFilename();
//截取后4位
String substring = originalFilename.substring(originalFilename.length()-4,originalFilename.length());
//生成当前时分秒
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
String format = simpleDateFormat.format(new Date());
//生成6位随机数
Random random = new Random();
int i = random.nextInt(100000);
//拼接新的名称
StringBuffer jp = new StringBuffer();
jp.append(format);
jp.append(i);
jp.append(substring);
System.out.println(jp.toString());
//调用工具类传入相应的值
//FTP地址 端口 帐号 密码 FTP中路径 文件名称 文件流
ftpUtil.uploadFile("192.168.1.91", 21, "txw", "123456", "/", jp.toString(), inputStream);
return "ok";
}
}
