springMVC上传，富文本上传和ftp服务器的配置

之前写过一个上传的方法，使用的是第三方jar包，这次使用springMVC内置的上传和富文本上传介绍，同时讲解链接ftp服务器的相关配置

ftpUtil的配置：

package com.mmall.until;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;/** * Created by Administrator on 2017/10/14. */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");    public FTPUtil(String ip, int port, String user, String pwd) {        this.ip = ip;        this.port = port;        this.user = user;        this.pwd = pwd;    }    //返回上传成功还是失败    public static boolean uploadFile(List<File> fileList) throws IOException {        FTPUtil ftpUtil = new FTPUtil(ftpIp,21,ftpUser,ftpPass);        logger.info("开始链接ftp服务器!");        //不是所有的异常都要被捕获，像这个异常就需要抛出到业务层处理，根据业务情况        boolean result = ftpUtil.uploadFile("image",fileList);        logger.info("开始ftp服务器，结束上传，上传结果：{}");        return result;    }    private boolean uploadFile(String remotePath,List<File> fileList) throws IOException {        /**         * remotePath(远程文件名)的作用：         * ftp服务器在Linux服务器上是一个文件夹，如果要在它的下级创建文件，就需要这个文件夹         */        boolean uploaded = true;//是否传了        FileInputStream fis = null;        //链接ftp服务器        if (conectServer(this.ip,this.port,this.user,this.pwd)){            try {                //更改工作目录                ftpClient.changeWorkingDirectory(remotePath);                //设置缓冲区                ftpClient.setBufferSize(1024);                ftpClient.setControlEncoding("UTF-8");                //设置文件类型为二进制文件类型，防止乱码                ftpClient.setFileType(ftpClient.BINARY_FILE_TYPE);                ftpClient.enterLocalPassiveMode();                for (File fileItem:fileList){                    fis = new FileInputStream(fileItem);//创建input流                    ftpClient.storeFile(fileItem.getName(),fis);                }            } catch (IOException e) {                logger.error("上传文件异常！",e);                uploaded = false;                e.printStackTrace();            }finally {                fis.close();                ftpClient.disconnect();            }        }        return uploaded;    }    //是否链接ftp成功    private boolean conectServer(String ip,int port,String user,String pwd){        boolean isSuccess = false;        ftpClient = new FTPClient();        try {            ftpClient.connect(ip);            isSuccess=ftpClient.login(user,pwd);        } catch (IOException e) {            logger.error("链接ftp服务器异常！",e);        }        return isSuccess;    }    private String ip;    private int port;    private String user;    private String pwd;    private FTPClient ftpClient;    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;    }}

@controller层：

//文件上传    @RequestMapping(value = "upload.do")    @ResponseBody    public 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.createByErrorMessage(ResponseCode.NEED_LOGIN.getCode(), "未登录，请强制登陆管理员！");        }        if (iUserService.checkAdminRole(user).isSuccess()) {            //填充业务            //文件上传后的路径，和webapp下index.jsp同级的文件夹            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！");        }    }    @RequestMapping("richtext_img_upload.do")    @ResponseBody    public 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;        }        //富文本中对于返回值有自己的要求,我们使用是simditor所以按照simditor的要求进行返回//        {//            "success": true/false,//                "msg": "error message", # optional//            "file_path": "[real file path]"//        }        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", true);            resultMap.put("msg", "上传成功");            resultMap.put("file_path", url);            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;        }    }

dispatch-servlet.xml的配置：

<!-- 文件上传 -->    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">        <property name="maxUploadSize" value="10485760"/> <!-- 10m -->        <property name="maxInMemorySize" value="4096" />        <property name="defaultEncoding" value="UTF-8"></property>    </bean>

测试页：

<%@page contentType="text/html; charset=UTF-8" language="java" %><html><body><h2>Hello World!</h2>springmvc上传文件<form name="form1" action="/manage/product/upload.do" method="post" enctype="multipart/form-data">    <input type="file" name="upload_file" />    <input type="submit" value="springmvc上传文件" /></form>富文本图片上传文件<form name="form2" action="/manage/product/richtext_img_upload.do" method="post" enctype="multipart/form-data">    <input type="file" name="upload_file" />    <input type="submit" value="富文本图片上传文件" /></form></body></html>

上传逻辑的实现：

package com.mmall.service.UserServiceImpl;import com.google.common.collect.Lists;import com.mmall.service.IFileService;import com.mmall.until.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;/** * Created by Administrator on 2017/10/14. */@Service("iFileService")public class FileServiceImpl implements IFileService {    private Logger logger = LoggerFactory.getLogger(FileServiceImpl.class);    public String upload(MultipartFile file,String path){        //拿到上传文件的原始文件名        String fileName = file.getOriginalFilename();        //扩展名        //abc.jpg        String fileExtensionName =fileName.substring(fileName.lastIndexOf(".")+1);        //为了防止名字重复的文件会被覆盖，采取如下拼接方式        String uploadFileName = UUID.randomUUID().toString()+"."+fileExtensionName;        logger.info("上传文件开始：上传的文件名{},上传的路径{},上传的新文件名{}",fileName,path,uploadFileName);        File fileDir = new File(path);        if (!fileDir.exists()){            //获得写的权限（在tomcat中创建文件，不一定有权限发布文件）            fileDir.setWritable(true);            //mkdirs 和 mkdir 的区别是创建多个和一个的区别            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ftp服务器上            FTPUtil.uploadFile(Lists.newArrayList(targetFile));            //已经上传到ftp服务器上            //  上传完成后删除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();    }}
