Abstract

With the continuous development of the agricultural mechanical and electrical recruitment industry, the use and popularization of agricultural mechanical and electrical recruitment in real life, the agricultural mechanical and electrical recruitment industry has become a new industry that has emerged in recent years, and can become a behavior and choice widely recognized and accepted by the masses. The purpose of designing the agricultural mechanical and electrical recruitment platform is to make complex sales operations simple and efficient with the help of computers.

The agricultural mechanical and electrical recruitment platform adopts the B/S structure, JAVA as the development language, the database adopts the B/S structure, and the Mysql database is developed. The system includes two parts of front-end operation and background management, on the one hand, to provide users with the home page, agricultural machinery, system announcements, personal center, background management and other functions; on the other hand, to provide administrators with homepage, personal center, agricultural machinery master management, user management, agricultural machinery type management, agricultural machinery management, agricultural machinery appointment management, system management and other functions.

【Keywords】Agricultural mechanical and electrical moves; JAVA; B/S structure
