if you are using spring boot + Spring OAuth you must add
@Order(Ordered.HIGHEST_PRECEDENCE)
to your CORS filter
@Configuration
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CORSFilter implements Filter {
private FilterConfig config;
@Override
public void destroy() {
}
@Override
public void doFilter(ServletRequest req, ServletResponse resp,
FilterChain chain) throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) resp;
HttpServletRequest request = (HttpServletRequest) req;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "x-requested-with, authorization, Content-Type, Authorization, credential, X-XSRF-TOKEN");
if ("OPTIONS".equalsIgnoreCase(request.getMethod())) {
response.setStatus(HttpServletResponse.SC_OK);
} else {
chain.doFilter(req, resp);
}
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
config = filterConfig;
}
}
