This article mainly introduces Java how to achieve hospital reservation registration system, the article introduces in great detail, has a certain reference value, interested friends must read it!

I. brief introduction of the project

Functions: users can be divided into patients, doctors, administrators, patients can register and choose doctors to register, select dates, select number sources, doctors can receive doctors, administrators can maintain users and doctor information, and so on.

II. Project operation

Environment configuration: Jdk1.8 + Tomcat8.5 + mysql + Eclispe (both supported by IntelliJ IDEA,Eclispe,MyEclispe,Sts)

Project technology: Jdbc+ Servlert + Jsp + css + JavaScript + JQuery + Ajax + Fileupload and so on.
