There are multiple ways of coding a web application. From servlet-jsp way to n-tiered applications. I am explaining here the layered architecture to create a web application using Rest to communicate between front-end and back-end.

We will use the following set of technologies in this tutorial. I will try to write step by step setup instructions.

Language:
Java

Database
mysql

Framework:
Spring

ORM Tool:
Hibernate

Secondary Level cache:
EHCache

Architecture:
Layered architecture using
-Controller for REST interaction.
-Service classes for business logic
-DAO layers for basic crud operations and databse interaction
-POJO objects to represent database tables

Build tool:
Gradle

Web Server:
Tomcat

Front-end:
AngularJS

JSON Object mapping:
Jackson

Test:
Junit

Logging:
Log4j
