ISRO CS Original Papers and Official Keys.GATE CS Original Papers and Official Keys.Only if added, we need to take care about the MIME type be given to "Content-Type" as that is given to (MediaType. If "Content-Type" field is not added to header, then we will get the response. TEXT_XML annotation will decide the format that client should sent the send the data.Ĭonsider the below code, as per the below code, client should send the data through query string and “Content-Type” filed in header should have “text/xml” value. It is standard and better convention to use .rs.core.MediaType constants instead of Consumes (value = MediaType. While specifying MIME type we can hardcode or we can use static constants present in .rs.core.MediaType as below. The annotation has an optional element “value” value for which should be a String/String array and String should be a valid MIME (value = "application/json" ) This annotation specifies the MIME type of the request. The service will give response and format will be as coded.Īssume, service is coded to return response in all format, and if specific format is not requested by the client (Accept field id not added to header) the response format will be as annotation can be applied at the class level and as well as at the method level. In such cases if service is giving response in any one format then it is better not to include “Accept” filed into header. Otherwise if client give some other value let’s say “application/json” to “Accept” field then since service is coded to return response only in XML, client will not get the response. If client includes “Accept” field into header then value for “Accept” filed should be “text/xml”. If service is coded to give response in only XML, then response format will be always XML. If in header, value for “Accept” field is “application/json” the response will be in JSON format. Usually client request the particular format in “Accept” field of header. But service will return the response in only one format depending upon the request.Īssume, service is coded to return response in all format, then the response format depends on the content type/format that requested by the client. Here is an example of an annotation element with only the value can configure our code to give response in only XML, or only JSON, or only HTML, or we can give response in the all the format. When an annotation just contains a single element named value, you can leave out the element name, and just provide the value. In case an annotation contains just a single element, it is convention to name that element value, like = "yes") It is standard and better convention to use .rs.core.MediaType constants instead of (value=MediaType. The annotation has an optional element “value” value for which should be a String/String array and String should be a valid MIME type. This annotation specifies the MIME type of the response. annotation should be used only for GET requests. annotation can be applied at the class level and as well as at the method level. Method annotated with will respond to DELETE request only. the HHTP DELETE request to the annotated HTTP DELETE method. Method annotated with will respond to PUT request only. the HHTP PUT request to the annotated HTTP PUT method. Method annotated with will respond to POST request only. the HHTP POST request to the annotated HTTP POST method. Method annotated with will respond to GET request only. the HHTP GET request to the annotated HTTP GET method. URL : Here is the part of URI, and this will be identified by annotation at class/method level. This annotation is used to associate URI to our REST Web service. Below is the list of important JAX-RS API annotations used in [, annotation can be applied at the class level and as well as at the method level.
