Viewed 2628

Im now developing simple spring boot web app.. Is there something in spring(filter) that check every request(headers).. I want to check if there is cookie.. If there is cookie- nothing happend.. But if there is not it would create cookie... Do i have to do this manually, so i put this in every function? Or can i do something like global function, that got executed with every other request?

Thanks for help.

yes you have to use filters you can try doing something like this

public class MyCookieFilter extends GenericFilterBean {

    public static final String MY_COOKIE_NAME = "your-cookie-name";


    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
        throws IOException, ServletException {
        HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;
        HttpServletResponse httpServletResponse = (HttpServletResponse) servletResponse;

        checkCookie(httpServletRequest, httpServletResponse);

        filterChain.doFilter(servletRequest, servletResponse);
    }

    private void checkCookie(HttpServletRequest request, HttpServletResponse servletResponse) {
        boolean cookieExists = Arrays.stream(request.getCookies()).anyMatch(cookie -> cookie.getName().equalsIgnoreCase(MY_COOKIE_NAME));
        if (!cookieExists) {
            String cookieValue = "your-cookie-value";
            Cookie newCookie = new Cookie(MY_COOKIE_NAME, cookieValue);
            servletResponse.addCookie(newCookie);
        }
    }
}

then add it in your security config

    @Override
    public void configure(HttpSecurity http) throws Exception {
    http
     ...
       .addFilter(new MyCookieFilter())
     ...
    }
