Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

Prerequisites

• You need to have MySQL installed on your machine to run the application in dev profile. Using the MySQL Workbench or on any other MySQL client/console, create a database/schema named reddit_clone.

-- create schema
CREATE SCHEMA reddit_clone;

-- use schema
USE reddit_clone;

-- Create user 
create user 'reddit_clone'@'localhost' identified by 'reddit_clone';

-- Grant privileges to user
grant all privileges on *.* to 'reddit_clone'@'localhost' with grant option;

After creating the database/schema, you need to add your MySQL username and password in the application-dev.properties file on src/main/resource. The lines that must be modified are as follows:

spring.datasource.url=jdbc:mysql://localhost:3306/reddit_clone?useSSL=false&allowPublicKeyRetrieval=true
spring.datasource.username=reddit_clone
spring.datasource.password=reddit_clone

• A Java Keystore File is required to generate JSON Web Token.

keytool -genkey -alias redditclone -keyalg RSA -keystore redditclone.jks -keysize 2048

Installing

Running the application with IDE

There are several ways to run a Spring Boot application on your local machine. One way is to execute the main method in the io.github.anantharajuc.rc.RedditCloneApplication class from your IDE.

• Download the zip or clone the Git repository.
• Unzip the zip file (if you downloaded one)
• Open Command Prompt and Change directory (cd) to folder containing pom.xml
• Open Eclipse
  • File -> Import -> Existing Maven Project -> Navigate to the folder where you unzipped the zip
  • Select the project
• Choose the Spring Boot Application file (search for @SpringBootApplication)
• Right Click on the file and Run as Java Application

Running the application with Maven

Alternatively you can use the Spring Boot Maven plugin like so:

$ git clone https://github.com/Spring-Boot-Framework/Reddit-Clone.git
$ cd Reddit-Clone
$ mvn spring-boot:run

Running the application with Executable JAR

The code can also be built into a jar and then executed/run. Once the jar is built, run the jar by double clicking on it or by using the command

$ git clone https://github.com/Spring-Boot-Framework/Reddit-Clone.git
$ cd Reddit-Clone
$ mvn package -DskipTests
$ java -jar target/Reddit-Clone-0.0.1-SNAPSHOT.jar --spring.profiles.active=dev

To shutdown the jar, follow the below mentioned steps on a Windows machine.

• In command prompt execute the jcmd command to print a list of all running Java processes
• Taskkill /PID PROCESS_ID_OF_RUNNING_APP /F execute this command by replacing the PROCESS_ID_OF_RUNNING_APP with the actual process id of the running jar found out from executing the previous command
