Java项⽬：⽹盘系统设计和实现（java+ssm+jpa）源码获取：博客⾸页 "资源" ⾥下载！
很多同学都有⾃⼰的⽹盘，⽅便存储⼀些java学习教程。该毕业设计实现了⼀个简易的⽹盘，包含⽂件上传和⽂件分享等功能。
后端技术采⽤了spring，spring mvc，JPA，前端采⽤了thymeleaf模板语⾔。整体业务功能相对不是太复杂，亮点是⽂件分享功能。
分享操作业务：
@Controller
public class ShareController {
private Logger logger = Class());
@Autowired
private LinkSecretServiceImpl linkSecretService;
@Autowired
private FileServiceImpl fileService;
private SaveServiceImpl saveService;
/**
* 安卓上查看分享记录的接⼝
*
* @return
*/
@RequestMapping(value = "/shareRecord", produces = "application/json; charset=utf-8")
@ResponseBody
public List<ShareMessage> shareRecord(HttpServletRequest request) {
User user = (User) Session().getAttribute("user");
String userName = UserName();
List<ShareMessage> shareMessageList = new ArrayList<>();
List<LinkSecret> linkSecretList = linkSecretService.findLinkSecretsByUserName(userName);
for (int i = 0; i < linkSecretList.size(); i++) {
LinkSecret linkSecret = (i);
ShareMessage shareMessage = new ShareMessage();
shareMessage.DownloadNum());
shareMessage.ExpireDate());
shareMessage.LocalLink().LocalLink().lastIndexOf("/")));
shareMessage.setDownloadName(null);
shareMessageList.add(shareMessage);
}
return shareMessageList;
}
//保存到⽹盘-----link是加密的链接    downloadLink解密后的链接/data/share/zc2/Fuck.java,  path：保存路径--是⽤户名后⾯的路径    @RequestMapping(value = "/shareToMyPan")
@ResponseBody
public ResponseMsg shareToMyPan(HttpServletRequest request, String path, String link) {
String downloadLink = "";
if (ains("/data/share")) {
downloadLink = link;
} else {
downloadLink = fileService.fileShareCodeDecode(link);
}
logger.warn("downloadLink:" + downloadLink);
boolean b = false;
ResponseMsg responseMsg = new ResponseMsg();
User user = (User) Session().getAttribute("user");
if (user == null) {
responseMsg.setSuccess(false);
responseMsg.setMsg("未登录");
} else {
String userName = UserName();
if (path == null) {
path = "/";
}
logger.warn(userName + " " + downloadLink + " " + path);
b = pyFileToMyPan(userName, downloadLink, path);
responseMsg.setSuccess(b);
if (b == false) {
responseMsg.setMsg("保存失败");
} else {
responseMsg.setMsg("保存成功");
}
}
return responseMsg;
}
/**

*/
@RequestMapping(value = "/downloadApk", produces = {"application/json; charset=UTF-8"})

if (!new File(filePath).exists()) {
responseMsg.setMsg("不到⽂件");
}
// 设置输出的格式
String agent = Header("user-agent");
String fileName4 = "";
if (ains("Firefox")) {
fileName4 = new Bytes(), "iso-8859-1");
} else {
//空格，（，），；，@，#，&，逗号在⾕歌浏览器中出现乱码

replaceAll("%28", "\\(").

replaceAll("%3B", ";").
replaceAll("%40", "@").
replaceAll("%23", "\\#").
replaceAll("%26", "\\&").
replaceAll("%2C", "\\,");
}
response.addHeader("Content-Disposition", "attachment; filename=\"" + fileName4 + "\"");
// 循环取出流中的数据
byte[] b = new byte[100];
