Spring Boot Example

Clone the below repo using the commands on windows git bash

## Get the code
# Versions jdk 19 and spring boot 3.3.3
git clone https://github.com/jeethualex/spring.git

## Build project
gradle build
mvn clean install

## Local run
gradle bootRun

## Run the jar file - with gradle
java -jar .\build\libs\demo-0.0.1-SNAPSHOT.jar

## Run the jar file - with maven
java -jar .\target\demo-0.0.1-SNAPSHOT.jar

###### GREETINGS ######

## launch urls below 

# http://localhost:8080/hello

curl http://localhost:8080/greeting?name=G2
curl http://localhost:8080/hello?name=G2


###### EMPLOYEES CRUD ######

## before running these commands will need a local mysql database server installed with 2 env variables
## will create a spring database with employee table
## Env variables needed to be added on windows are MYSQl_USER and MYSQL_PASS
