How to get the HTTP method of a REST request

In case of an exception in my Java REST application I would like to log various information on causing HTTP request.

I can obtain the URI of the request and the HTTP headers via context injection

@Context
private UriInfo uriInfo;

@Context
private HttpHeaders headers;

But how can I obtain the HTTP method (GET, PUT, ...)?

Jersey is irrelevant (following the most upvoted answer.)

HttpServletRequest class of Java Servlet API has getMethod() method that returns the name of the HTTP method (GET, POST, PUT, etc).

But you do not always need it. For example, if you are in servlet, you have doGet, doPost methods.

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   //method is POST
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { //method is GET }

But you do need it, for example, in the filter:

public void doFilter(ServletRequest request, ServletResponse response, 
          FilterChain chain) throws ServletException, IOException {

     String method = ((HttpServletRequest) request).getMethod();

}

Speaking of the REST, different REST frameworks may provides various ways to obtain the HttpServletRequest object.

I use Jersey. Don't know if this applies for you but ... : 

import javax.servlet.http.HttpServletRequest;    

@Context final HttpServletRequest request

The Request class has the method getMethod(). It returns the used HTTP method.

You are usually limiting the rest methods to one http method

 @GET
 @Produces("text/plain")
  public String getClichedMessage() {
    // Return some cliched textual content
    return "Hello World";
 }
