public class CrossInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object o) throws Exception {
        if (request.getHeader(HttpHeaders.ORIGIN) != null) {
            String origin = request.getHeader("Origin");
            response.addHeader("Access-Control-Allow-Origin", origin);
            response.addHeader("Access-Control-Allow-Credentials", "true");
            response.addHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PUT,PATCH, HEAD");
            response.addHeader("Access-Control-Allow-Headers", "Content-Type");
            response.addHeader("Access-Control-Max-Age", "3600");
        }
        return true;
    }
}

先试试直接拦截处理
