springmvc文件上传

文件上传

一、Springmvc文件上传到ftp服务器

FileServiceImpl：

package com.hcxmall.service.impl;import com.google.common.collect.Lists;import com.hcxmall.service.IFileService;import com.hcxmall.util.FTPUtil;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Service;import org.springframework.web.multipart.MultipartFile;import java.io.File;import java.io.IOException;import java.util.UUID;/** * 文件上传 * * @author HCX * @create 2017 - 11 - 16 15:01 */@Service("iFileService")public class FileServiceImpl implements IFileService{    private Logger logger = LoggerFactory.getLogger(FileServiceImpl.class);    @Override    public String upload(MultipartFile file,String path){        String fileName = file.getOriginalFilename();        //获取扩展名        String fileExtensionName = fileName.substring(fileName.lastIndexOf(".") + 1);        //为了防止用户上传了相同的文件名        String uploadFileName = UUID.randomUUID().toString()+"."+fileExtensionName;        //记录日志        logger.info("开始上传文件，上传文件的文件名：{}，上传的路径：{}，新文件名：{}",fileName,path,uploadFileName);        File fileDir = new File(path);        if(!fileDir.exists()){            //赋予权限：可写            fileDir.setWritable(true);            //makedir()：当前级别            //makedirs():如果上传的文件所在的文件夹是-a-b-c-d，上传到服务器 这些目录都没有，则使用makedirs()            fileDir.mkdirs();        }        File targetFile = new File(path,uploadFileName);        try {            file.transferTo(targetFile);            //文件已经上传成功了            //将targetFile上传到我们的FTP服务器上            FTPUtil.uploadFile(Lists.newArrayList(targetFile));            //上传完之后，删除upload下面的文件            targetFile.delete();        } catch (IOException e) {            logger.error("上传文件异常",e);            return null;        }        return targetFile.getName();    }}

FTPUtil:

package com.hcxmall.util;import org.apache.commons.net.ftp.FTPClient;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.util.List;/** * 文件上传到服务器 * * @author HCX * @create 2017 - 11 - 16 15:36 */public class FTPUtil {    private static final Logger logger = LoggerFactory.getLogger(FTPUtil.class);    private static String ftpIp = PropertiesUtil.getProperty("ftp.server.ip");    private static String ftpUser = PropertiesUtil.getProperty("ftp.user");    private static String ftpPass = PropertiesUtil.getProperty("ftp.pass");    private String ip;    private int port;    private String user;    private String pwd;    private FTPClient ftpClient;    public FTPUtil(String ip, int port, String user, String pwd) {        this.ip = ip;        this.port = port;        this.user = user;        this.pwd = pwd;    }    public static boolean uploadFile(List<File> fileList) throws IOException {        //port是固定的21        FTPUtil ftpUtil = new FTPUtil(ftpIp,21,ftpUser,ftpPass);        logger.info("开始连接ftp服务器");        //传到ftp服务器文件夹下的img文件夹        boolean result = ftpUtil.uploadFile("img",fileList);        logger.info("开始连接ftp服务器，结束上传，上传结果：{}");        return result;    }    /**     *     * @param remotePath 远程路径：上传到ftp服务器上，ftp服务器在Linux下是一个文件夹，     *                   如果需要上传到ftp文件夹中再下一层文件的话，就需要使用remotePath，使上传的路径多一些     * @param fileList     * @return     * @throws IOException     */    private boolean uploadFile(String remotePath,List<File> fileList) throws IOException {        boolean uploaded = true;        FileInputStream fis = null;        //连接FTP服务器        if(connectServer(this.ip,this.port,this.user,this.pwd)){            try {                //更改工作目录：切换文件夹，不想切换传空即可                ftpClient.changeWorkingDirectory(remotePath);                //设置缓冲区                ftpClient.setBufferSize(1024);                ftpClient.setControlEncoding("UTF-8");                //文件类型设置成二进制，防止乱码                ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);                //打开本地被动模式                ftpClient.enterLocalPassiveMode();                for(File fileItem : fileList){                    fis = new FileInputStream(fileItem);                    //存储文件                    ftpClient.storeFile(fileItem.getName(),fis);                }            } catch (IOException e) {                logger.error("上传文件异常",e);                uploaded = false;                e.printStackTrace();            }finally {                //关闭流                fis.close();                //释放连接                ftpClient.disconnect();            }        }        return uploaded;    }    /**     * 连接ftp服务器     * @param ip     * @param port     * @param user     * @param pwd     * @return     */    private boolean connectServer(String ip,int port,String user,String pwd){        boolean isSuccess = false;        ftpClient = new FTPClient();        try {            //连接            ftpClient.connect(ip);            //登录            isSuccess = ftpClient.login(user,pwd);        } catch (IOException e) {            logger.error("连接FTP服务器异常",e);        }        return isSuccess;    }    public String getIp() {        return ip;    }    public void setIp(String ip) {        this.ip = ip;    }    public int getPort() {        return port;    }    public void setPort(int port) {        this.port = port;    }    public String getUser() {        return user;    }    public void setUser(String user) {        this.user = user;    }    public String getPwd() {        return pwd;    }    public void setPwd(String pwd) {        this.pwd = pwd;    }    public FTPClient getFtpClient() {        return ftpClient;    }    public void setFtpClient(FTPClient ftpClient) {        this.ftpClient = ftpClient;    }}

上传到ftp服务器的一些配置信息hcxmall.properties：

ftp.server.ip=182.92.82.103ftp.user=hcxmallftpftp.pass=ftppassword#搭建的图片服务器的前缀ftp.server.http.prefix=http://img.happymmall.com/

读取properties文件的工具类：

package com.hcxmall.util;import org.apache.commons.lang.StringUtils;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import java.io.IOException;import java.io.InputStreamReader;import java.util.Properties;/** * 配置文件工具类 * @author HCX * @create 2017 - 11 - 15 18:28 */public class PropertiesUtil {    private static Logger logger = LoggerFactory.getLogger(PropertiesUtil.class);    private static Properties props;    //在tomcat启动时读取里面的配置:使用静态代码块    //执行顺序：静态代码块（在类被加载的时候执行且仅执行一次）>普通代码块>构造代码块    //静态代码块：一般用于初始化静态变量。    static{        String fileName = "hcxmall.properties";        props = new Properties();        try {            props.load(new InputStreamReader(PropertiesUtil.class.getClassLoader().getResourceAsStream(fileName),"UTF-8"));        } catch (IOException e) {            logger.error("配置文件读取异常",e);        }    }    /**     * 获取hcxmall.propeties文件中的信息：通过key获取value     * @param key     * @return     */    public static String getProperty(String key){        String value = props.getProperty(key.trim());        if(StringUtils.isBlank(value)){        return null;    }        return value.trim();}    public static String getProperty(String key,String defaultValue){        String value = props.getProperty(key.trim());        if(StringUtils.isBlank(value)){            value = defaultValue;        }        return value.trim();    }}

调用：

/** * 文件上传 * @param file * @param request * @return */@RequestMapping("upload.do")@ResponseBodypublic ServerResponse upload(HttpSession session,                             @RequestParam(value = "upload_file",required = false) MultipartFile file,                             HttpServletRequest request){    User user = (User) session.getAttribute(Const.CURRENT_USER);    if(user == null){        return ServerResponse.createByErrorCodeMessage(ResponseCode.NEED_LOGIN.getCode(),"用户未登录，请登录管理员");    }    if(iUserService.checkAdminRole(user).isSuccess()){        //上传到upload文件夹，此目录为webapp下的，即跟WEB-INF同级        String path = request.getSession().getServletContext().getRealPath("upload");        String targetFileName = iFileService.upload(file, path);        String url = PropertiesUtil.getProperty("ftp.server.http.prefix") + targetFileName;        Map fileMap = Maps.newHashMap();        fileMap.put("uri",targetFileName);        fileMap.put("url",url);        return ServerResponse.createBySuccess(fileMap);    }else {        return ServerResponse.createByErrorMessage("无权限操作");    }}

二、富文本文件上传

富文本中对于返回值有自己的要求，这里使用simditor 所以按照simditor的要求进行返回 该种富文本上传只针对simditor插件：

{   "success":true/false,    "msg":"error message",# optional   "file_path":"[real file path]" }

demo：

@RequestMapping("richtext_img_upload.do")@ResponseBodypublic Map richtextImgUpload(HttpSession session,                             @RequestParam(value = "upload_file",required = false) MultipartFile file,                             HttpServletRequest request,                             HttpServletResponse response){    Map resultMap = Maps.newHashMap();    User user = (User) session.getAttribute(Const.CURRENT_USER);    if(user == null){        resultMap.put("success",false);        resultMap.put("msg","请登录管理员");        return resultMap;    }    if(iUserService.checkAdminRole(user).isSuccess()){        String path = request.getSession().getServletContext().getRealPath("upload");        String targetFileName = iFileService.upload(file, path);        if(StringUtils.isBlank(targetFileName)){            resultMap.put("success",false);            resultMap.put("msg","上传失败");            return resultMap;        }        String url = PropertiesUtil.getProperty("ftp.server.http.prefix") + targetFileName;        resultMap.put("success",false);        resultMap.put("msg","上传成功");        resultMap.put("file_path",url);        //只需要处理正常的成功的返回        response.addHeader("Access-Control-Allow-Headers","X-File-Name");        return resultMap;    }else {        resultMap.put("success",false);        resultMap.put("msg","无权限操作");        return resultMap;    }}

附上之前做项目时写的文件上传demo，只是上传到本地，没有上传到ftp服务器：

调用：

//编辑签约列表信息@RequestMapping("/editSignManage")@ResponseBody@Transactionalpublic Result editSignManage(SignManage signManage,                             @RequestParam(value = "file1", required = false) CommonsMultipartFile[] file1, @RequestParam(value = "name1", required = false) String[] name1,                             @RequestParam(value = "file2", required = false) CommonsMultipartFile[] file2, @RequestParam(value = "name2", required = false) String[] name2,                             @RequestParam(value = "file3", required = false) CommonsMultipartFile[] file3, @RequestParam(value = "name3", required = false) String[] name3,                             HttpServletRequest request) throws IOException {    //前端要给的数据：customerId,signManageId    //前端传递客户id    Map<String, Object> resultMap=(Map<String, Object>)request.getAttribute("data");    if (signManage.getCustomerId() != null) {        fileUploadUtils.uploadFile(file1, name1, signManage.getCustomerId(), "图片", fileUploadUtils.CONTRACT_SIGN_ONE);        fileUploadUtils.uploadFile(file2, name2, signManage.getCustomerId(), "图片", fileUploadUtils.CONTRACT_SIGN_TWO);        fileUploadUtils.uploadFile(file3, name3, signManage.getCustomerId(), "图片", fileUploadUtils.CONTRACT_SIGN_THREE);    }    if (signManage.getSignManageId() == null) {        //插入        boolean isSuccess = signManageService.addSignManage(signManage,resultMap);        if (!isSuccess)            return new Result(StatusCode.E_PARAM, "添加失败");        return new Result(StatusCode.OK, "添加成功");    } else {        //更新        boolean isSuccess = signManageService.updateSignManage(signManage,resultMap);        if (!isSuccess)            return new Result(StatusCode.E_PARAM, "编辑失败");        return new Result(StatusCode.OK, "编辑成功");    }}

生成图片名字工具类：
