# From 'A' to 'Web App': Build an API in Java

I wrote [this tutorial](https://www.roboleary.net/java/2020/06/03/spring-boot-api.html) to fill a void that I have noticed. Building web applications is a top priority for people learning backend development, but I haven’t seen any Java or Spring Boot tutorials that is friendly for beginners. Most tutorials are either too trivial ([Hello World API](http://spring.io/guides/gs/rest-service/)) to help you understand what you need to know; or they are overwhelming and assume too much about what you already know!

The [second part of the tutorial](https://www.roboleary.net/testing/2020/06/15/api-testing.html) covers testing this web service. The corresponding code is contained in the "with-tests" branch, the code differs slightly from the "master" branch, and includes the unit tests discussed.

  

## What you’ll build

You’ll build a web service that can create, read, update, and delete users.

![get request example](img/demo.jpg)

The default local address for your Spring Boot application will be: [http://localhost:8080](http://localhost:8080),

so the address to get all users would be [http://localhost:8080/users](http://localhost:8080/users) for example.

We will create the following actions:

 

   

     HTTP Method

     Address

     Action

   

   

     GET

     /users

     Get all users

   

   

     GET

     /users/{id}

     Get users by id

   

   

     GET

     /users?name=rob+oleary

     Get user by name

   

   

     POST

     /users

     Add a new user

   

   

     PUT

     /users

     Update a user

   

   

     DELETE

     /users/{id}

     Delete a user

   

 

 

 [The tutorial](https://www.roboleary.net/java/2020/06/03/spring-boot-api.html) outlines prerequisites and provides a step-by-step guide to building the web serivce.
