👺 takeaway

Recently fat in brush Java after all, studies will have to consider the road behind ah, do not understand the backend Java foundation and learn several mainstream framework how can not say past it. Then I tried to write me this Java novice can complete the king of Glory Rock Kingdom version of the simulation game has not added the front end for the time being, after finishing brushing the frame in the back. All right, let’s cut to the chase

👺 Project Introduction

The project uses the MVC+DAO pattern, which is a popular pattern at present. MVC means

The letter	Said meaning
M	Model, model layer, Javabeans
V	View view layer, servlet and JSP front-end page
C	The controller control layer

DAO is the data persistence layer. The whole project is very featureless,Its only characteristic is a large amount of simple code with video especially suitable for beginners to practiceIt also covers radiation, regular expressions, and other techniques.

There are many Java classes in each package

👺 Function Description

I would like to emphasize that there is no malice in the names that appear in the introduction, but I was personally drawn to them during the creation of Age of Awakening.
