ABSTRACT
From the end of the last century.Internet technology has developed rapidly.With the advent of the information age, we can see the charm of the Internet in just 10 years.The Internet is everywhere in our lives, and the information explosion expands.How to get the information.
In the information age of information exchange platform, sharing microblog is particularly important. People can freely search and release information, obtain the latest and most timely consultation, timely and highly interactive.With the popularity of Weibo among netizens, the influence of web celebrity and hot words on the Internet has gradually formed.The microblog system adopts the B / S architecture to realize the original foundation.We improve the user experience by adding problem rewards to existing microblogging systems and introducing new features such as points.Implement the technology, the page uses JSP, JavaScript, ajax and other technologies to enhance the interaction of the system page with users.The background uses the Java language, the server uses the Tomcat server, and uses SSM.It uses a framework MySQL database to implement specific functionality to store the data.

The fifth chapter System function realization

5.1 Landing system
After the user enters the email address on the system login registration page , The mailbox entered by the user passes ajax Send to the background controller , And in Service The layer calls the corresponding method . stay Service In the method , call Dao Layer interface to find user mailbox , If you register , Whether registered or not , Will pass through the front end JavaScript Show on page , Remind the user that the email has been registered . Enter the basic information and click Register , The registration information entered by the user is sent to http://1278.cn/ The controller , The controller controls the forwarding page of the request , Send to user . Initialize some basic information of users in the service , Such as the registration information of the service 、 Default Avatar 、 Default state 、 Initialize user points and other actions , Assemble user data sources , call Dao Layer method saves user registration do. The information is shown in the figure below 5.1. Here is the core code ：

user.setRegisterTime(nowDate());		// Use the current time as the user registration time 
	user.setLastLogin(nowDate());
	user.setBirthday("2017-1-1");
	User addUser = addIntegral(user, Constant.REGISTER);		// Increase user points 
	action = userDao.findIntegral(Constant.REGISTER);		// Find the result of the registration operation PointAction
	record = new PointRecord(action, addUser.getEmail(), nowDate());
	addIntegralRecord(record);	// Save integral operation 
userDao.saveUser(addUser); 	// Save user registration information 
 Login function , Then click auto login password , Click to log in , First, pass the user name and password information to the service layer for business processing , And then call Dao The layer interface verifies whether the mailbox and password information are correct . If correct , Save the email name and password in the browser the next time you click login cookie in , Store the logged in user in session in , Judge whether the current login time and the last login time of the user are the same. The user is http ://1287.cn  One day in the service of processing login , Otherwise, increase the user's login points , Modify the number of points in the user database , Then enter the homepage of Weibo ./5.2. Here is the core code ：
findUser = userDao.findUserByEmailAndPassword(userId, password);
	if(findUser == null){
    
		throw new UserServiceException(" Wrong user name or password ");
	}else{
    
		Date lastLogin = findUser.getLastLogin();	// Last login time 
		Date now = nowDate();	// current time 
		if(lastLogin.getYear()!=now.getYear() || lastLogin.getMonth()!=now.getMonth() || lastLogin.getDate()!=now.getDate()){
    
		// Judge if the last login time is different from this login time , Add login points for users 
		findUser=addIntegral(findUser, Constant.LOGIN);	// Save points 
		saveIRecord(findUser, Constant.LOGIN);	// Keep score records 
		findUser.setLastLogin(now);		// Change the last login time to the current time 
		userDao.updateUser(findUser);	// Change user information 
			}
}
