How to Use Open API 3 tools in our Spring Boot Project | Its alternate of Swagger tools

 Setting up spring doc-open API

To have springdoc-openapi automatically generate the OpenAPI 3 specification docs for our API, we simply add the springdoc-openapi-ui dependency to our pom.xml:

<dependency>

    <groupId>org.springdoc</groupId>

    <artifactId>springdoc-openapi-ui</artifactId>

    <version>1.5.2</version>

</dependency>

Then when we run our application, the OpenAPI descriptions will be available at the path /v3/api-docs by default:

http://localhost:8080/v3/api-docs/

To use a custom path, we can indicate in the application.properties file:

springdoc.api-docs.path=/api-docs

Now we'll be able to access the docs at:

http://localhost:8080/api-docs/

The OpenAPI definitions are in JSON format by default. For yaml format, we can obtain the definitions at:

http://localhost:8080/api-docs.yaml

If you want to test like post man then this is for you.

Now we can access the API documentation at:

http://localhost:8080/swagger-ui.html
