Spring MVC does not handle RequestMethod.OPTIONS - spring

Question

I am in the context of a Rest API. As I am performing cross domain request, I need to send back the header "Access-Control-Allow-Origin".
I have a controller such:
#Controller
#RequestMapping("/api")
public class PackageManagerRestController {
#RequestMapping(method = RequestMethod.OPTIONS, value = "/test")
public void commonOptions(HttpServletResponse theHttpServletResponse) throws IOException {
theHttpServletResponse.addHeader("Access-Control-Allow-Headers", "origin, content-type, accept, x-requested-with");
theHttpServletResponse.addHeader("Access-Control-Max-Age", "60"); // seconds to cache preflight request --> less OPTIONS traffic
theHttpServletResponse.addHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");
theHttpServletResponse.addHeader("Access-Control-Allow-Origin", "*");
}
#RequestMapping(method = RequestMethod.GET, value = "/test")
public void getPtions(HttpServletResponse theHttpServletResponse) throws IOException {
theHttpServletResponse.addHeader("Access-Control-Allow-Headers", "origin, content-type, accept, x-requested-with");
theHttpServletResponse.addHeader("Access-Control-Max-Age", "60"); // seconds to cache preflight request --> less OPTIONS traffic
theHttpServletResponse.addHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");
theHttpServletResponse.addHeader("Access-Control-Allow-Origin", "*");
}
}
If I run a test with GET, the result is as expected:
$ curl -i -X GET http://localhost:8081/api/test
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Access-Control-Allow-Headers: origin, content-type, accept, x-requested-with
Access-Control-Max-Age: 60
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *
Content-Length: 0

However, if I send the request with OPTIONS, the controller never handles the request:
$ curl -i -X OPTIONS http://localhost:8081/api/test
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Allow: GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, PATCH
Content-Length: 0

Anyone has any clue of why I am receiving this "default response" and why I cannot customize it ?

Answer 1

For default Spring DispatcherServlet supports GET, HEAD, POST, PUT, PATCH and DELETE only; if you want to support TRACE and OPTIONS you have to put "dispatchOptionsRequest" and "dispatchTraceRequest" properties to "true"; check here docs.spring.io/spring/docs/4.0.3.RELEASE/javadoc-api
In order to support OPTIONS too in your web.xml you have to put this:
<init-param>
<param-name>dispatchOptionsRequest</param-name>
<param-value>true</param-value>
</init-param>
By adding it I can handle OPTIONS:
~$ curl -i -X OPTIONS http://localhost:8180/sample/api/test
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Access-Control-Allow-Headers: origin, content-type, accept, x-requested-with
Access-Control-Max-Age: 60
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *
Allow: GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, PATCH
Content-Length: 0

Answer 2

according to the last answer
I resolve my problem
#RequestMapping(value = "/**",method = RequestMethod.OPTIONS)
public String getOption(HttpServletResponse response,Model model)
{
response.setHeader("Access-Control-Allow-Origin","*");
response.setHeader("Access-Control-Allow-Methods", "GET,PUT,POST,DELETE");
return "";
}
and we need to add something to the dispacherservlet
<init-param>
<param-name>dispatchOptionsRequest</param-name>
<param-value>true</param-value>
</init-param>
and this is over
