REST tutorial : Controller layer

Greetings!

This is the last post of our RESTful webservice section 1 ;) . Previous part is here
We still have to implement error handling, security etc

You can find the complete source code here Todoapp

Step 1: Create TodoController annotated with @RestController


Step 2: Implement our methods. Spring will do the REST ;)


Let's test our service using Postman.
start the server, gradle clean bootrun

Test 1: Empty Todos
Note the status: since we do not have any Todos yet, it is 404



Test 2: Create a Todo
We get the 201 status and created Todo's location in header



Test 3: List Todos



Test 4: Update a Todo



Test 5: Delete a Todo




That is all for now, though it is working we are yet to handle errors properly and secure our end points.

REST tutorial : Create repository

Greetings!

This is the 2nd post of our tutorial series. Previous part is here
In this part let's create our domain quickly.

You can find the complete source code here Todoapp
Spring Data JPA Spring Data JPA improves the implementation of data access layers by reducing boilerplate codes. For the repository interfaces Spring provides the implementation automatically.
https://projects.spring.io/spring-data-jpa/

Lombok Lombok reduces boilerplate code for model objects. It can generate getter, setter, toString, hashCode, equals, constructors for you. https://projectlombok.org

To make it simple, we will have Todo with Id, title and summary.

Step 1: Modify database properties


Step 2: Create Todo model


NOTE: Lombok will eliminate getter, setter, toString, hashCode burden.

Step 3 : Create Todo repository


With magic of Spring that is all ;)
