creating api documentation with swagger in a spring boot application is a great way to enhance the usability of your api. swagger provides a user-friendly interface to interact with your api, making it easier for developers to understand and use it. below is a step-by-step tutorial on how to integrate swagger into a spring boot application, along with a code example.

step 1: set up your spring boot project

you can create a spring boot project using [spring initializr](https://start.spring.io/) or by setting up a maven/gradle project manually. for this tutorial, we will use maven.

1. *create a new spring boot project*
choose `spring web` as a dependency.
choose `spring boot devtools` for easier development.
choose `spring data jpa` and a database dependency if needed (like h2 for in-memory database).
choose `spring configuration processor` for better configuration support.

2. *update your `pom.xml` for swagger*

add the following dependencies in your `pom.xml`:

```xml
dependency
groupidio.springfox/groupid
artifactidspringfox-boot-starter/artifactid
version3.0.0/version
/dependency
dependency
groupidio.springfox/groupid
artifactidspringfox-swagger2/artifactid
version3.0.0/version
/dependency
dependency
groupidio.springfox/groupid
artifactidspringfox-swagger-ui/artifactid
version3.0.0/version
/dependency
```

step 2: create a sample rest api

create a simple rest controller to demonstrate how swagger works.

```java
package com.example.demo.controller;

import org.springframework.web.bind.annotation.getmapping;
import org.springframework.web.bind.annotation.requestparam;
import org.springframework.web.bind.annotation.restcontroller;

@restcontroller
public class hellocontroller {

@getmapping("/hello")
public string hello(@requestparam(value = "name", defaultvalue = "world") string name) {
return "hello, " + name + "!";
}
}
```
