SpringMVCHandler.java

   /**
     * REST PUT
     */
    @RequestMapping(value="/order",method=RequestMethod.PUT)

    public String testRestPUT() {
        System.out.println("REST PUT");
        return "success";
    }
    /**
     * REST POST
     */
    @RequestMapping(value="/order",method=RequestMethod.POST)
    public String testRestPOST() {
        System.out.println("REST POST");

        return "success";
    }


    /**

     */
    @RequestMapping(value="/order/{id}",method=RequestMethod.DELETE)

    public String testRestDELETE(@PathVariable("id")Integer id ) {
        System.out.println("REST DELETE: " + id );
        return "success";
    }

    /**

    @RequestMapping(value="/order/{id}",method=RequestMethod.GET)
    public String testRestGET(@PathVariable("id")Integer id ) {
        System.out.println("REST GET: " + id );
        return "success";
    }
