Learn Spring Boot by Annotations

This is a simple Spring Boot RESTful web service.

REST endpoints:

  • PUT /api/weather with WeatherRJ as body: Save weather data for a city
  • GET /api/weather/: Query weather data of a city

WeatherRJ data object: { "city": String, "temperature": Int }

Moreover, this app performs a regular background task, calculating the average temperature of all weather data. This task runs every 20 seconds.

Run the app yourself

Prerequisites:

  • Java 8 JDK
  • Maven
  • Git
  • curl

Download the code and run the app:

git clone https://github.com/pmgysel/spring-boot-annotations.git
cd spring-boot-annotations
mvn clean install
java -jar target/spring-boot-annotations-0.0.1-SNAPSHOT.jar

Now you can create and read weather data using the exposed REST endpoints.

curl on Linux:

curl -H "Content-Type: application/json" -X PUT -d '{"city":"zurich","temperature":22}' http://localhost:8080/api/weather
curl -X GET http://localhost:8080/api/weather/zurich

curl on Windows:

curl -H "Content-Type: application/json" -X PUT -d "{\"city\":\"zurich\",\"temperature\":22}" http://localhost:8080/api/weather
curl -X GET http://localhost:8080/api/weather/zurich
