Quick Annotation Overview

When it comes to describing the contact person for an OpenAPI definition, setting up annotations is a crucial step in the process. In this article, we'll take a closer look at the swagger 3 annotations and how they can be used to generate OpenAPI metadata.

The first thing to note is that by default, only methods annotated with the `@Operation` annotation are considered for inclusion in the OpenAPI definition. This behavior can be controlled through the configuration property `readAllResources`, which defaults to true.

However, when it comes to swagger-jaxrs2 reader engine, things work a bit differently. By default, this engine includes methods of scanned resources that are not annotated with `@Operation` as well. This is because JAX-RS is defined at both the class and method level, along with HTTP method annotations.

To use the swagger 3 annotations effectively, it's essential to have a good understanding of their usage. Each annotation has links to its javadocs, which can be found in the header and at the end of the overview section. For convenience, the javadocs and petstore sample are also available.

One important thing to note is that having `@OpenAPI` required at the class level is necessary for OpenAPI scan root resources, as per JAX-RS compliance. This ensures that the correct output is generated in compliance with the OpenAPI Specification.

The core output of swagger-core is compliant with the OpenAPI Specification, but users are not required to be familiar with all aspects of the specification to use it. However, having a basic understanding can help answer any questions regarding the generated output.

To generate the OpenAPI documentation, swagger-core provides a set of annotations that can be used to declare and manipulate the output. These annotations provide a flexible way to customize the output and ensure compliance with the OpenAPI Specification.

In addition, since version 2.1.7, swagger-core supports the Jakarta namespace, which provides the same functionality as the standard javax namespace but with a parallel set of artifacts with a -jakarta suffix. This allows users to take advantage of the newer features and improvements while still maintaining compatibility with existing codebases.

Finally, since version 2.2.0, swagger-core supports OpenAPI 3.1, which provides additional features and enhancements over previous versions. For those looking for information on swagger 1.5.X and OpenApi 2.0, there are separate resources available that provide more detailed information on setup and usage.

Overall, the swagger 3 annotations provide a powerful way to customize and generate OpenAPI metadata, making it easier to create accurate and comprehensive documentation for APIs. By understanding how these annotations work and how they can be used effectively, developers can take full advantage of the features and benefits offered by swagger-core.
