Project No.: Java+spring ssm285 novel reading website \graduation design
Development language: Java
Development tools: IDEA /Eclipse
Database: MYSQL5.7
Application service: Tomcat7/Tomcat8
Using framework: ssm+vue
Project introduction
The development of the Internet has driven the rapid development of the novel industry. All major websites can see the shadow of novel reading. The increase of readers has further inhibited the improvement of market consumption. With the increasingly fierce market competition, although many authors take the initiative to choose the credit sales model, they lack sufficient attention and good quality control. Some authors have not established independent credit practice management, It is unable to accurately obtain the reader's credit information in the early stage of the transaction, but it is easy to perform the credit, which makes it impossible to get a benign improvement.
Novel reading website, the main modules include viewing; administrators; Homepage, personal center, reader management, author management, novel information management, novel classification management, balance recharge management, purchase novel management, download novel management, system management, readers; Personal center, balance recharge management, purchase novel management, download novel management, my collection management, etc. Author: personal center, novel information management, novel classification management, balance recharge management, purchase novel management, download novel management, my collection management. Home page: novel information, my, jump to backstage function. The administrator in the system is mainly to store and manage all kinds of information safely and effectively, and can also manage, update and maintain the system, and have corresponding operation permissions for the front and back desks.
