随着农机电招行业的不断发展，农机电招在现实生活中的使用和普及，农机电招行业成为近年内出现的一个新行业，并且能够成为大群众广为认可和接受的行为和选择。设计农机电招平台的目的就是借助计算机让复杂的销售操作变简单，变高效。

农机电招平台采用了B/S结构，JAVA作为开发语言，数据库采用了B/S结构，Mysql数据库进行开发。该系统包括前台操作和后台管理两个部分，一方面，为用户提供首页，农机，系统公告，个人中心，后台管理等功能；另一方面，为管理员提供首页，个人中心，农机机主管理，使用者管理，农机类型管理，农机管理，农机预约管理，系统管理等功能。

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
