springboot-sandbox

Need to rewrite everything

a little sandbox for an easy start playing with spring boot features

Build and startup

From command line you can do

mvn clean package

this will create the standard spring boot jar inside the target direcotry

You can start up the sand box in different ways

As a standalone jar

java -jar springboot-sandbox-0.0.1-SNAPSHOT

With a maven (thanks to the spring-boot-maven-plugin)

mvn spring-boot:run

Running the main of the SpringbootSandboxApplication class (with an IDE)

This project include the spring-boot-devtools and is ready for the auto reload even with maven.

<build>
	<plugins>
		<plugin>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-maven-plugin</artifactId>
			<configuration>
				<fork>true</fork>
			</configuration>
		</plugin>
	</plugins>
</build>

You need the fork in the plugin

The autoreload is triggered when the files in the classpath change(needs a build -> CTRL+F9 in intellij)

Testing the app

Handles and behaviour

Endpoints

/greeting -> You need to be logged in to be greet

/auth/token -> JWT token, you should be logged in to see this. Check the token here

POST Some data to the H2 db

    curl -v -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{  "firstName" : "Frodo",  "lastName" : "Baggins" }'  http://localhost:8080/people

Security

For test purpose there is some security implemented as basic http

you can access with

username: poldo

password: poldone

You can change it in the SpringbootSandboxApplication class

Health check

You can check the status of services at /health Actually is just the basic check of Actuator
