Foreword

At present, we are in the era of informationization. Many industries are adapting to the changes of the times and using computer technology to move towards digitalization and informationization construction. In the past, enterprises used manual registration to save relevant data for the management and control of blog information. This human-based management model has fallen behind. I combined the use of mainstream program development technology to design a streamlined blog system based on Springboot, which can greatly reduce the loss of human and financial resources and facilitate relevant personnel to update and save information in a timely manner. This system mainly uses the B/S development model. On the idea development platform, it uses Java language to design related system function modules, MySQL database management related system data information, SSM framework design and development system functional architecture, and finally by using Tomcat server. Publish the designed system in the browser and complete the interaction between the system and the database. This article provides a more detailed introduction to the system’s demand analysis, feasibility analysis, technical support, functional design, database design, functional testing, etc. This article also shows the system’s main functional module design interface and operation interface, and Necessary explanations are given to facilitate users to operate and use the system, and relevant personnel to update and maintain the system in the future. The implementation of this system can greatly improve the work efficiency of enterprises and enhance the user experience. Therefore, the use of this system in real life has great value.

2. Introduction to system functions

Personal Center

Through the designed personal center management function module, administrative users can manage relevant personal information. For example, administrative users can update the password information of personal accounts, modify the username information of personal accounts, etc.

Administrator management

Through the designed administrator management function module, administrative users can manage relevant administrator information, such as viewing the administrator’s user name, updating the administrator’s password information, deleting logged-out administrator information records, etc.

User Management

Through the designed employee management function module, management users can manage relevant user information, such as viewing user names, modifying user contact information, deleting logged-out user information records, etc.

Basic Data Management

Through the designed basic data management function module, management users can manage related blog types, post types, and announcement types. For example, management users can view detailed information about blog types, post types, and announcement types, and delete invalid blog types, Post type, announcement type information records, etc.

Blog information management

Through the designed blog information management function module, management users can manage related blog information. For example, management users can view blog content information, delete invalid blog information records, etc.

Blog comment management

Through the designed blog comment information management function module, management users can manage related blog comment information. For example, management users can view blog comment content information, delete invalid blog comment information records, etc.

Blog collection management

Through the designed blog collection management function module, management users can manage related blog collection information. For example, management users can view blog collection time information, delete expired blog collection information records, etc.

Forum Management

Through the designed forum management function module, management users can manage relevant forum information. For example, management users can view forum post content information, delete invalid forum information records, etc.

Announcement Information Management

Through the designed announcement information management function module, management users can manage relevant announcement information. For example, management users can view announcement time information, delete invalid announcement information records, etc.

Through the designed carousel management function module, management users can manage related carousel information. For example, management users can view carousel name information, delete expired carousel information records, etc.
