Summary

With this, we have reached the end of this chapter. Let’s recap the valuable things you have learned.

First, you learned about the available features and properties of springdoc-openapi and how to configure and use the OpenAPI specification to generate the JSON and YAML documentation for our API calls. You also learned how to access Swagger UI, an interactive documentation tool for calling APIs directly in a browser. We simulated this to send test calls and modify certain behaviors, such as the domain URL and the sorting order. This newly acquired knowledge for generating documentation for APIs is very useful in real-world applications. This knowledge is used by developers to easily identify the available APIs that can be consumed, as well as their parameters and object responses.

In the next chapter, we will learn about the concept of Cross-Origin Resource Sharing (CORS), Spring Security, and JSON Web Tokens (JWTs).
