Annotate resource methods within a JAX-RS class with @POST or @PUT to indicate that some content is being passed to
the method. The following briefly summarizes the different HTTP methods that can be used for consuming content:
POST updates an existing resource or creates a new resource.
PUT creates a new idempotent resource.
To specify the type of content being passed, annotate the same method with @Consumes(content-type) .
The following excerpt demonstrates the use of @Consumes :
public class SimpleRest {
public String add(@QueryParam("text") String text){
this.message = text;
return message;
Note that the add method specifies the @Path annotation, so it becomes accessible by appending the add string to
the URI that was specified in the class's @Path . To input a new message stating Java , you would visit a URL using the
following format in your browser, which would pass the new message to the text variable:
