基于filter

      import org.springframework.beans.factory.annotation.Value;
      import org.springframework.stereotype.Component;
      import javax.servlet.*;
      import javax.servlet.http.HttpServletRequest;
      import javax.servlet.http.HttpServletResponse;
      import java.io.IOException;
      import java.util.ArrayList;
      import java.util.List;
      import java.util.regex.Matcher;
      import java.util.regex.Pattern;
      @Component
      public class CORSFilter implements Filter {
         @Value("${cors.allowedOrigins}")
         private String[] allowedOrigins;
         @Override
         public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
                  throws IOException, ServletException {
              HttpServletRequest req = (HttpServletRequest) request;
              String requestOrigin = req.getHeader("Origin");
              List<Pattern> allowedOriginsRegex &#
