![]() For example, = "/users", produces = "application/json") would match any request with a URL path of “/users” that has an Accept header of application/json. produces: This attribute specifies the media type(s) that the request can produce.For example, = "/users", consumes = "application/json") would match any request with a URL path of “/users” that has a Content-Type header of application/json. consumes: This attribute specifies the media type(s) that the request can consume.For example, = "/users", headers = "Content-Type=text/plain") would match any request with a URL path of “/users” that has a Content-Type header of text/plain. headers: This attribute specifies the request header conditions that should be met for the request mapping to be considered a match.For example, = "/users", params = "id") would match any request with a URL path of “/users” that has an “id” parameter. params: This attribute specifies the request parameter conditions that should be met for the request mapping to be considered a match.For example, = "/users", method = RequestMethod.GET) would match any GET request with the URL path “/users”. It can take a RequestMethod value such as GET, POST, PUT, DELETE, etc. method: This attribute specifies the HTTP method that the request mapping should apply to.For example, would match any request with the URL path “/users”. value: This attribute specifies the URL path that the request mapping should apply to.Some of the commonly used attributes are: When using the annotation at method-level in a Spring Boot application, the annotation provides a number of attributes that can be used to customize the behavior of a request mapping. You can learn more about these annotations in this tutorial Spring Annotations and Attributes of the Annotation It’s worth noting that the annotation is usually used at class-level to define the root URL for a controller, while the shorthand annotations are used at method-level to specify the HTTP request method and the path for the endpoint. Additionally, Spring Boot provides other related annotations, such as and that are shorthand annotations for the annotation with a specific HTTP method. For example, a GET request to the /users URL path can be used to retrieve a list of users from a database, while a POST request to the same URL path can be used to create a new user in the database.īy using the annotation, you can create powerful and flexible request mappings that can handle a wide variety of requests and parameters. The annotation is commonly used in RESTful web services to map HTTP request methods to specific Java methods that handle those requests. This will tell Spring Boot that this Java method should handle GET requests to the /users path. For example, if a developer wants to handle a GET request to the /users URL path, they can annotate the Java method that should handle the request with = "/users", method = RequestMethod.GET). The annotation can be used to specify the request type (GET, POST, PUT, DELETE) and the corresponding method that will handle the request. ![]() This means that when a request is sent to the web application, Spring Boot will use the annotation to determine which Java method should handle the request. The annotation is a core annotation in Spring Boot that is used to map a specific HTTP request method to a specific Java method in a web application.
