3 Controller 获取html上传的multipartfile
controller 接受html传来的文件后 先将该文件存放在本地tomcat某目录下(具体可以自行打印文件的路径查看)。
然后读取本地文件的路径和文件名(文件名经过了sha256加密) 新建输入流
调用FTPUtil的上传接口 上传 到服务器上同时删除本地的缓存文件
上传成功则跳转success界面可继续添加
否则进入wrong界面
ps:本例中只针对ipa 和mount文件进行上传
package com.example.demo.controller;
import com.example.demo.util.FTPUtil;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.security.MessageDigest;
import java.text.SimpleDateFormat;
import java.util.Date;
@Controller
@RequestMapping("/app/")
public class UploadController {
@Value("${upload.host}")
private String host;
@Value("${upload.port}")
private int port;
@Value("${upload.userName}")
private String userName;
@Value("${upload.password}")
private String password;
@Value("${upload.basePath}")
private String basePath = "/";
private String filePath;
@RequestMapping("upload")
public String upload(MultipartFile uploadFile, HttpServletRequest req){
SimpleDateFormat sd = new SimpleDateFormat("yyyy/MM/dd");
String realPath = req.getSession().getServletContext().getRealPath("/uploadFile");
String format = sd.format(new Date());
File file = new File(realPath + format);
if (!file.isDirectory()){
file.mkdirs();
}
String oldName = uploadFile.getOriginalFilename();
MessageDigest messageDigest;
try{
messageDigest = MessageDigest.getInstance("SHA-256");
messageDigest.update(oldName.substring(0, oldName.indexOf(".")).getBytes());
String newName = byte2Hex(messageDigest.digest()) + oldName.substring(oldName.indexOf("."));
File storeFile = new File(file, newName);
uploadFile.transferTo(storeFile);
InputStream in = new FileInputStream(storeFile);
String prefix = oldName.substring(oldName.indexOf("."), oldName.length());
if(prefix.equals(".ipa")){
filePath = "/iTunes";
}else if(prefix.equals(".macho")){
filePath = "/MARSRESCAN";
}else{
return "/wrong.html";
}
boolean res = FTPUtil.uploadFile(host, port, userName, password, basePath, filePath, newName, in);
boolean delete = storeFile.delete();
if(res && delete){
return "/success.html";
}
}catch (Exception e){
e.printStackTrace();
}
return "/wrong.html";
}
private String byte2Hex(byte[] bytes) {
StringBuffer stringBuffer = new StringBuffer();
String temp = "";
for (int i = 0; i < bytes.length; i++) {
temp = Integer.toHexString(bytes[i] & 0XFF);
if(temp.length() == 1){
stringBuffer.append("0");
}
stringBuffer.append(temp);
}
return stringBuffer.toString();
}
}
FTPUtil
用来连接ftp服务器 上传文件。
具体测试的时候可以在自己本机搭建一个ftp server 百度有教程
basePath 服务器的根目录
filePath 文件的存放文件夹
package com.example.demo.util;
import org.apache.commons.net.ftp.FTP;
import org.apache.commons.net.ftp.FTPClient;
import java.io.IOException;
import java.io.InputStream;
public class FTPUtil {
public static boolean uploadFile(String host, int port, String username, String password, String basePath,
String filePath, String filename, InputStream input) {
boolean result = false;
FTPClient ftp = new FTPClient();
try {
int reply;
ftp.connect(host, port);
ftp.login(username, password);
if (!ftp.changeWorkingDirectory(basePath+filePath)) {
//如果目录不存在创建目录
String[] dirs = filePath.split("/");
String tempPath = basePath;
for (String dir : dirs) {
if (null == dir || "".equals(dir)) continue;
tempPath += "/" + dir;
if (!ftp.changeWorkingDirectory(tempPath)) {
if (!ftp.makeDirectory(tempPath)) {
return result;
} else {
ftp.changeWorkingDirectory(tempPath);
}
}
}
}
//设置上传文件的类型为二进制类型
ftp.setFileType(FTP.BINARY_FILE_TYPE);
//上传文件
if (!ftp.storeFile(filename, input)) {
return result;
}
input.close();
ftp.logout();
result = true;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (ftp.isConnected()) {
try {
ftp.disconnect();
} catch (IOException ioe) {
}
}
}
return result;
}
}
4 重要的配置文件
server:
port: 8088
spring:
resources:
static-locations: classpath:/templates
servlet:
multipart:
max-file-size: 200MB
max-request-size: 200MB
upload:
host: 10.64.167.95
port: 21
userName:
password:
basePath: /
总结
实现文件的上传遇到两个坑
1 html与controller之间的调用:
刚开始发现请求app/upload无法相应 后来发现是IDEA的默认端口号是63342 html请求时用的不是80
将IDEA的默认端口号改过来就行了
2 这个坑没法记录 苹果的catlinna系统似乎在读取本地存储文件上需要特殊设置 后来在win上开发就没问题了
