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 ="[email protected]";  //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 ; }}

2.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(); }}

3.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 class="qqBox">
<div class="BoxHead"> <div class="headImg"> <img /> <!--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 class="internetName">${userInfo.userName}</div> </div> <div class="context"> <div class="conRight"> <div class="Righthead"> <div class="headName">${userInfo.nickName}</div> <div class="headConfig"> <ul> <li><img/></li> <li><img/></li> <li><img/></li> <li><img/></li> </ul> </div> </div> <div class="RightCont"> <ul class="newsList">
</ul> </div> <div class="RightFoot"> <div class="footTop"> <ul> <li><img/></li> <li class="ExP"><img/></li> <li><img/></li> <li><img/></li> <li><img/></li> <li><img alt="" /></li> <li><img/></li> <li><img/></li> </ul> </div> <div class="inputBox"> <textarea id="dope"  name="" rows="" cols=""></textarea> <button class="sendBtn">发送(s)</button>
</div> </div> </div> </div></div>

4.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
