核心代码:
  1. 注册使用邮箱验证码
//邮件对象public class EmailModel {	private String title;//标题	private String receiverEmail;//接收人邮箱	private String text;//发送内容	public static String register="欢迎来到微博客\n您的注册为:";	public static String registerTitle="注册验证码";	public static String findPwdTitle="找回密码：";	public static String findPwdText="找回密码验证码：";}// 邮件发送public class EmailUtils {	private final static String authorizationCode="khdotvxxxxdba"; 	//授权码-自己设置	private final static String senderEmail ="1022287044@qq.com";	//发送人邮箱--测试邮箱	//发送邮件方法	public static int sendEmail(EmailModel emailModel){  try{   Properties props = new Properties();   // 开启debug调试   props.setProperty("mail.debug", "false");   // 发送服务器需要身份验证   props.setProperty("mail.smtp.auth", "true");   // 设置邮件服务器主机名   props.setProperty("mail.host", "smtp.qq.com");   // 发送邮件协议名称   props.setProperty("mail.transport.protocol", "smtp");   MailSSLSocketFactory sf = new MailSSLSocketFactory();   sf.setTrustAllHosts(true);   props.put("mail.smtp.ssl.enable", "true");   props.put("mail.smtp.ssl.socketFactory", sf);   Session session = Session.getInstance(props);   Message msg = new MimeMessage(session);   msg.setSubject(emailModel.getTitle());//标题   StringBuilder builder = new StringBuilder();   builder.append(emailModel.getText());   msg.setText(builder.toString());   msg.setFrom(new InternetAddress(senderEmail));//发送人的邮箱地址   Transport transport = session.getTransport();   //发送人的邮箱地址 //你的邮箱密码或者授权码   transport.connect("smtp.qq.com", senderEmail, authorizationCode);   transport.sendMessage(msg, new Address[] { new InternetAddress(emailModel.getReceiverEmail()) });// 接收人的邮箱地址   transport.close();   return 1;  }catch (Exception e){  e.printStackTrace();  return 0;  }	 }}//注册及发送邮箱验证码public void doGet(HttpServletRequest request, HttpServletResponse response) { try{  PrintWriter printWriter=response.getWriter();  HttpSession session=request.getSession();  String action = request.getParameter("action");  String userName=request.getParameter("userName");  String password=request.getParameter("password");   if("sendEmail".equals(action)){			//发送验证码   String receiverEmail=request.getParameter("receiverEmail");   String type=request.getParameter("type");   String authCode=RandomUtil.randomNumbers(4);   EmailModel emailModel=new EmailModel();   if("register".equalsIgnoreCase(type)){ //注册    User search=new User();    search.setUserName(receiverEmail);    search=userService.getUser(search);    if(null!=search){     printWriter.println("2");     return;    }else{     emailModel.setTitle(EmailModel.registerTitle);     emailModel.setText(EmailModel.register+authCode);    }   }else{								//找回密码    emailModel.setTitle(EmailModel.findPwdTitle);    emailModel.setText(EmailModel.findPwdText+authCode);   }   System.out.println("邮箱验证码："+authCode);   emailModel.setReceiverEmail(receiverEmail);   int result= EmailUtils.sendEmail(emailModel);   session.setAttribute(receiverEmail+"#EmailCode",authCode);//注册验证码   printWriter.println(result);  }else if("doRegister".equals(action)){					//注册验证   String authCode=request.getParameter("authCode");//验证码   String sessionCode=(String)session.getAttribute(userName+"#EmailCode");//注册验证码   if(null==sessionCode){    printWriter.println("3");					//验证码为空，请先获取邮箱验证码   }else if(!sessionCode.equals(authCode)){    printWriter.println("2");					//验证码错误   }else{    User user=new User();    user.setUserName(userName);    user.setNickName(userName);    user.setPassword(password);    int result=userService.addUser(user);    printWriter.println(result);				//验证成功   }  } }catch (Exception e){  e.printStackTrace();  return ; }}
  1. 上传头像
protected void doGet(HttpServletRequest request, HttpServletResponse response) { try {  // 配置上传参数  PrintWriter printWriter = response.getWriter();  String fileName = "";  DiskFileItemFactory factory = new DiskFileItemFactory();  ServletFileUpload upload = new ServletFileUpload(factory);  String userId = request.getParameter("userId");  String type = request.getParameter("type");  if (null != userId && !"".equals(userId)) {   List<FileItem> formItems = upload.parseRequest(request);   for (FileItem item : formItems) {   // 迭代表单数据    if (!item.isFormField()) {     String fileName2 = item.getName(); //重置乱码中文     fileName = RandomUtil.randomString(5) + (fileName2.substring(fileName2.indexOf(".")));     String filePath = String.format("%s/%s", SystemConfig.fileUploadPath, fileName);     File storeFile = new File(filePath);     item.write(storeFile);     // 保存文件到硬盘    }   }   if (null == type || "".equalsIgnoreCase(type)) {    String userUpload = SessionUtils.getUserUpload(Integer.valueOf(userId), request);    if (null != userUpload && !"".equalsIgnoreCase(userUpload)) {     userUpload = userUpload + fileName + ",";    } else {     userUpload = fileName + ",";    }    SessionUtils.setUserUpload(Integer.valueOf(userId), userUpload, request);    printWriter.println("0");   } else if ("headPic".equalsIgnoreCase(type)) {//头像    SessionUtils.setUserHeadPic(Integer.valueOf(userId), fileName, request);    printWriter.println("0");   }  } else {   printWriter.println("0"); //用户信息未找到  }  printWriter.close(); } catch (Exception ex) {  ex.printStackTrace(); }}
  1. 个人聊天（发送消息及读取消息实现）
//消息采用读取数据库模式实现，并非socket或者其他通讯主件public void doGet(HttpServletRequest request, HttpServletResponse response) { HttpSession session=request.getSession(); PrintWriter printWriter=response.getWriter(); String action = request.getParameter("action"); User user= SessionUtils.getUser(request); if ("sendMsg".equals(action)) {		//发送消息  String message=request.getParameter("message");  String receiveId=request.getParameter("receiveId");  Chat chat=new Chat();  chat.setUserId(user.getId());  chat.setUserName(user.getNickName());  chat.setMessage(message);  chat.setStatus(0);  chat.setReceiveId(Integer.valueOf(receiveId));  chat.setCreateTime(DateUtil.formatDateTime(new Date()));  Posts posts=new Posts();  posts.setReleaseId(user.getId());  chatService.addChat(chat);  printWriter.println("0");  session.setAttribute(user.getId()+":"+receiveId,message);  //添加推送  Notice notice=new Notice();  notice.setNoticeUserId(Integer.valueOf(receiveId));  notice.setUserId(user.getId());  notice.setNoticeType(3);  notice.setIsRead(0);  Notice isExtis=noticeService.getNotice(notice);  if(null==isExtis){   System.out.println("添加推送");   notice.setUserName(user.getUserName());   notice.setPostTitle(message);   noticeService.addNotice(notice); //添加通知  }else{   System.out.println("有未读消息，不添加推送");  } }else if ("getMsg".equals(action)) {		//获取消息  String sendUserId=request.getParameter("sendUserId"); //发送人id  String receiveId=request.getParameter("receiveId"); //接收人  Chat chat=new Chat();  chat.setUserId(Integer.valueOf(sendUserId));  chat.setReceiveId(Integer.valueOf(receiveId));  chat.setStatus(0);  List<Chat> list=chatService.getChatList(chat);  if(list.size()>0){   printWriter.println(JSONUtil.toJsonStr(list));   for(Chat c:list){    c.setStatus(1);    chatService.updateChat(c);   }  }else{   printWriter.println("");  }  printWriter.close(); }}//前端jsp页面代码<div > <div >  <div >   <img src="images/upload/${userInfo.headPic}" />   <!--当前自己-->   <input value="images/upload/${loginUser.headPic}" id="loginUserHeadPic" type="hidden"/>   <input value="${loginUser.id}" id="sendUserId" type="hidden"/>   <!--对方好友-->   <input value="images/upload/${userInfo.headPic}" id="userInfoHeadPic" type="hidden"/>   <input value="${userInfo.id}" id="receiveId" type="hidden"/>  </div>  <div >${userInfo.userName}</div> </div> <div >  <div >   <div >    <div >${userInfo.nickName}</div>    <div >     <ul>      <li><img src="images/chat/20170926103645_06.jpg"/></li>      <li><img src="images/chat/20170926103645_08.jpg"/></li>      <li><img src="images/chat/20170926103645_10.jpg"/></li>      <li><img src="images/chat/20170926103645_12.jpg"/></li>     </ul>    </div>   </div>   <div >    <ul >    </ul>   </div>   <div >    <div >     <ul>      <li><img src="images/chat/20170926103645_31.jpg"/></li>      <li ><img src="images/chat/20170926103645_33.jpg"/></li>      <li><img src="images/chat/20170926103645_35.jpg"/></li>      <li><img src="images/chat/20170926103645_37.jpg"/></li>      <li><img src="images/chat/20170926103645_39.jpg"/></li>      <li><img src="images/chat/20170926103645_41.jpg" alt="" /></li>      <li><img src="images/chat/20170926103645_43.jpg"/></li>      <li><img src="images/chat/20170926103645_45.jpg"/></li>     </ul>    </div>    <div >     <textarea id="dope" name="" rows="" cols=""></textarea>     <button >发送(s)</button>    </div>   </div>  </div> </div></div>
  1. 关注 粉丝 喜欢统计
//每一项根据用户id单独统计在组装数据public void getLikeFansNul(Integer userId,HttpServletRequest request){ String fansSql="select count(id) from t_likeuser where likeUserId="+userId; int fansNum= JDBCUtils.getCount(fansSql); String likeSql="select count(id) from t_likeuser where userid="+userId; int likeNum= JDBCUtils.getCount(likeSql); String collectSql="select count(id) from t_collection where userid="+userId; int collectNum= JDBCUtils.getCount(collectSql); CountsVo countsVo=new CountsVo(fansNum,likeNum,collectNum); SessionUtils.setCountsVo(countsVo,request);}
项目注意事项
1: 收藏和关注才会有通知 

2：收藏自己的推文没有通知

3：聊天消息推送如果有一条当前人发送的消息未读时，只保存一条未读消息

4：消息采用读取数据库模式实现，并非socket或者其他通讯主件,后期会单独起一个项目完成socket版本及其他三方开源的通信主件版本，敬请关注及更新
