2. Project introduction
With the end of the epidemic, the economic situation across the country is gradually improving. After three years, the demand for tourism has exploded to a certain extent. The outbreak of Spring Festival tourism is a good illustration. The recovery of the tourism industry will also take a certain amount of time. Three years have brought many tourism-related industries to a standstill. And the operation of the homestay is even worse.
How to use new technology, new technologies, and the Internet to promote and attract traffic for these homestay operators is the problem to be studied in this project. Based on the related application of JAVA technology, this topic develops an online publicity and reservation platform for characteristic homestays, in order to provide some help for these characteristic homestay operators, and to facilitate more travel enthusiasts to find more on this platform. A homestay that suits you will bring you a better experience.
This system mainly uses the SSM framework and MYSQL database. It is developed and implemented based on IDEA development tools. It has completed an online platform system for homestays, which enables front-end users to browse online and book homestays, share homestay travel strategies, map location homestays and other operations, background management User management Registered users, homestay information, travel guides and other basic information, and provides basic operations for user interaction, such as comments, favorites, feedback messages, etc.
The development and design of this system are mainly carried out around the homestay and its surrounding information. The important business modules mainly include homestay information, surrounding tourism information, homestay strategy, industry information, etc., to realize online booking by users, map location of homestay, and realize according to user preferences. Personalized homestay recommendation processing using collaborative filtering algorithm, etc. There are mainly two types of users, one is front-end registered users, and the other is platform management users. The following shows the use case diagrams of these two types of users, specifically as follows:
The user use case diagram is as follows:
(1) Front-end user use case diagram, as shown in Figure 1:
Figure 1 Front-end user use case diagram
The administrator user use case diagram is shown in Figure 2 below:
Figure 2 Background User Use Case Diagram
The characteristic homestay management platform mainly manages some information related to homestay, realizes online information display and reservation, so as to promote consumers to better understand homestay and bring more traffic to homestay operators. The overall functional structure design diagram As shown in Figure 3 below.
Figure 3 Functional Structure Diagram
Functional module introduction for front-end users:
(1) Registration and login function module design
Front-end users need to register as an online member when performing related operations. After filling in personal account information and personal information, they can log in after successful registration.
(2) Design of personal information management functional modules
After the user logs in to the system, he can enter the system management to modify the password, enter the old password, new password and confirm the password. If the new password is consistent with the confirmed password, the modification is successful, and if they are inconsistent, the modification fails.
(3) Information browsing function module
Front-end users can browse homestay information, related scenic spots information, homestay strategy information, industry information, etc. on the homestay platform, view details of various types of information, and comment online, and save favorite homestays or attractions.
(4) Online reservation function module
After the front-end user logs in, enter the details page of the homestay introduction, click the reservation button, book the homestay online, and manage the homestay he booked in the personal center. After the background administrator approves, the reservation is considered successful.
(5) B&B strategy module
Users can post online, write their own feelings about homestay accommodation, or travel strategy information of a certain scenic spot, and can manage their own posts online.
(6) Personalized recommendation module
The B&B management platform system will perform relevant calculations based on the user’s browsing records, and use collaborative filtering algorithms to recommend corresponding information to different users. The current data model is mainly based on the characteristics of the B&Bs browsed by users, matching relevant B&Bs information, and display the recommendation in the recommendation module on the home page.
(7) Full-text search module
In the homestay management platform system, front-end users can search based on relevant keywords, and will match the full text of homestay information, scenic spot information, etc., perform fuzzy matching according to the title description, and display the found information.
(8) Complaints and Suggestions
In addition to providing users with interactive functions such as online comments and favorites, it also provides a complaint and suggestion module, so that users can feedback relevant opinions in a timely manner, and the background administrator will handle them.
Functional module introduction for back-end users:
(1) Personal information management: The administrator can perform corresponding management operations on personal information by logging in to the background.
(2) User management: The administrator can perform corresponding management operations on the user information registered at the front end.
(3) Carousel map management: Carry out corresponding management operations on the carousel map information on the front-end home page, and replace the carousel map according to needs.
(4) Industry information management: mainly manage and publish relevant dynamic news information of the homestay industry.
(5) Homestay management: Mainly manage the published homestay information, introduce the location and characteristics of the homestay in detail, and specify the map location coordinates of the homestay in the background, which allows front-end users to directly locate the homestay location through Baidu Maps.
(6) Attraction management: mainly manage the relevant scenic spot information near the homestay, and complete the operation of adding, deleting, modifying and checking the scenic spot information.
(7) Order management: It mainly manages the order information of the front-end users. After the front-end members book the homestay, they need to be reviewed by the administrator in the background, and they can check in and use it after it takes effect.
(8) Raiders management: Mainly manage the front-end B&B member user releases and B&B strategy information.
(9) Complaints and Suggestions: Perform relevant management operations on complaints and suggestions issued by front-end users.
Three, system display
3.1 Realization of the front-end interface of the system
The interface design of the system mainly includes the design and realization of the system's login interface, main interface and various functional interfaces. The following shows the relevant functional modules implemented by the front-end member users of the featured homestay.
3.1.1 Implementation of the registration and login function interface
After filling in the registration information on the user registration page, you can log in. If you forget the password, you can also reset the new password according to the account and the mobile phone number at the time of registration. The following shows the registration and login interface, as shown in Figure 4-1 and Figure 4. -2 shows:
