What are some important annotations which you use to create Rest

Annotations are commonly used in frameworks like JAX-RS (Java) to define and configure RESTful web services. Here are some important annotations commonly used in JAX-RS to create RESTful web services:

  1. @Path: This annotation is used to specify the base URI path for a resource class or method. It allows you to define the URI pattern that will be used to access the resource.
  2. @GET, @POST, @PUT, @DELETE, @PATCH: These annotations are used to specify which HTTP method a resource method supports. For example, @GET is used to handle HTTP GET requests, @POST is used to handle HTTP POST requests, and so on.
  3. @PathParam: This annotation is used to inject values from path parameters into resource method parameters. It allows you to extract values from the URI path and use them in your resource methods.
  4. @QueryParam: This annotation is used to inject values from query parameters into resource method parameters. It allows you to extract values from the query string of the request URI and use them in your resource methods.
  5. @Consumes: This annotation is used to specify the MIME media types that a resource method can consume. It allows you to restrict the types of data that a method can accept in the request body.
  6. @Produces: This annotation is used to specify the MIME media types that a resource method can produce. It allows you to specify the format of the data that will be returned by the method.
  7. @HeaderParam: This annotation is used to inject values from HTTP headers into resource method parameters. It allows you to extract values from the headers of the request and use them in your resource methods.
  8. @DefaultValue: This annotation is used to specify default values for query parameters or path parameters. It allows you to provide fallback values if a parameter is not provided in the request.

These are some of the most commonly used annotations in JAX-RS for creating RESTful web services. They provide a convenient way to define and configure your resources, specify the HTTP methods they support, and extract data from the request URI, headers, and body.
