[FIXED] Disable HTTP OPTIONS method in spring boot application

Issue

I had developed rest API on spring boot application. The APIs accept only GET , and POST , but on requesting using OPTIONS method , API responding 200 status (instead of 405). I googled this issue , but none of the solution was springboot based .

Response:

Allow: OPTIONS, TRACE, GET, HEAD, POST
Public: OPTIONS, TRACE, GET, HEAD, POST

Need to disable OPTIONS method.

Solution

Previous answer is for tomcat only, so adding mine as well. You can disable the method cross-container by, for example, using a standard servlet filter:

import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import org.springframework.stereotype.Component;     
import org.springframework.web.filter.OncePerRequestFilter; 

@Component
public class MethodFilter extends OncePerRequestFilter { 

    @Override 
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) 
                    throws ServletException, IOException { 
        if (request.getMethod().equals("OPTIONS")) {
            response.sendError(HttpServletResponse.SC_METHOD_NOT_ALLOWED);
        } else { 
            filterChain.doFilter(request, response); 
        } 
    }
} 

Note: it is assumed that this class is componentscanned by Spring. If not, you can use other registration methods as detailed in here.
