AI BriefingEfficient API Documentation Using OpenAPI Specification
Key point
Introduces a method for integrating the reliability of Spring REST Docs with the usability of Swagger through OpenAPI Specification (OAS).
Details
Swagger, an API documentation tool, offers good usability but has drawbacks such as low reliability due to the lack of enforced testing and annotations mixed into business logic. Spring REST Docs, on the other hand, guarantees high reliability through testing and doesn't pollute the source code, but its UI isn't polished and it doesn't support API testing features.
To take advantage of both tools' strengths, OpenAPI Specification (OAS) is used. With the restdocs-api-spec open source project, you can generate an OAS file based on Spring REST Docs test results, and then visualize it with Swagger-UI to improve usability.
The implementation steps are as follows:
- Install Swagger-UI static files and configure Static Routing
- Set up a build environment to generate OAS files using restdocs-api-spec
- Write a script to copy the generated OAS file into the Swagger directory
- Write REST Docs test code using MockMvc
