Manipulate url parameters Restful API

Question

I just need to know how to manipulate url parameters when someone calls my API with parameters.

http://localhost:8100/apis/employee?firstName=john&lastName=Do 

I want to use these firstName and lastName parameters on my GET method but I don't know how to extract them.

@GET
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public Response getEmployee() {

//Just need to extract the parameters in here so I can use on the logic to return only the ones that meet the requirements. 

}

Any help would be appreciated. I am using SpringBootApplication on Java

By the annotations shown in your question, you are using JAX-RS (probably with Jersey). So use @QueryParam:

@GET
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public Response getEmployee(@QueryParam("firstName") String firstName, 
                            @QueryParam("lastName") String lastName) {
   ...
}

For Spring MVC (that also provides REST capabilities), you want to use @RequestParam:

@RequestMapping(method = RequestMethod.GET,
                produces = { MediaType.APPLICATION_XML_VALUE, 
                             MediaType.APPLICATION_JSON_VALUE })
public Response getEmployee(@RequestParam("firstName") String firstName, 
                            @RequestParam("lastName") String lastName) {
   ...
}

Both JAX-RS (with Jersey) and Spring MVC can be used with Spring Boot. See the documentation for details.
