Getting Started

To install this application, run the following commands:

git clone https://github.com/NiteshReddi/EcommerceApplication.git spring-boot-ecommerce
cd EcommerceApplication

This will get a copy of the project installed locally. To configure all of its dependencies and start each app, follow the instructions below.

Configure Database

Once MySQL is installed you must configure a username and password. By default the user and password should be root . If not, you must configure in the file application.configure located in the path src/main/resources/.

In the file application.configure you must edit the parameters spring.datasource.username and spring.datasource.password with the values you defined.

Create Database & Tables

Now you just need to create the database where the project will store the information. To create it, just follow the steps below.

mysql -u {username} -p

This command will ask for your MySQL password. Once inside the MySQL monitor you can create the database with the following command.

CREATE DATABASE ecommerce;

Now you can run the server which generates the database tables. To run the server, run:

./mvnw spring-boot:run

Create admin user

Before continuing you must create the user admin, in order to perform administrator operations in the application. For this you must create a user on the MySQL monitor with the following command.

USE ecommerce;
INSERT INTO user (username, email, is_admin, password) values ('{admin.username}', '{admin.email}', true, '{admin.password}');
