核心代码:
- 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 ;
}
}
- 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 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();
}
}
- 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 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
${userInfo.userName}
${userInfo.nickName}
- 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
