Java annotations on parameters1/16/2024 The annotation will be used as the (HTTP) method field of the operation, and the tell us the path of the operation (operations are grouped under the same path, one for each HTTP method used). Keep in mind that Java has type erasure, so using generics in the return type may not be parsed properly, and the response should be used directly. Since we want to return a list of pets, we declare that using the responseContainer. If the returned object is the actual result, it can be used directly instead of declaring it in the annotation. Notice that the actual method declaration returns a Response but that is a general-purpose JAX-RS class and not the actual response sent to the user. response is the return type of the method. The annotation MatricParam is used to retrieve the parameter value from the URI and assign it to a method parameter. you can include request samples and responses here). The notes allows you to give significantly more details about the operations (e.g. Since this is displayed in the list of operations in Swagger-UI and the location is limited in size, this should be kept short (preferably shorter than 120 characters). The value of the annotation is a short description on the API. Only classes that are annotated with will be scanned by Swagger. It serves a double purpose - it affects the Resource Listing and the API Declaration.

Let's list all Swagger core annotations that are RESTFul API Documentation in Java. If you are not familiar with Swagger, you should visit its web page to learn more before continuing with this article. Check out javadocs of these annotations on Swagger Annotations JavaDocs. The javadocs provide you with additional information about each annotation, especially dealing with some edge cases. Annotations offer an alternative to the use of XML descriptors and marker interfaces. Theyre a powerful part of Java that was added in JDK5. Įach annotation also has links to its javadocs . Java annotations are a mechanism for adding metadata information to our source code. The swagger-core output is compliant with Swagger Specification. In order to generate the Swagger documentation, swagger-core offers a set of annotations to declare and manipulate the output. In this article, we will explore all Swagger core annotations used for RESTFul API Documentation in Java.
