SpringBoot —— 后端拦截器配置跨域

@Component
public class CrossOriginInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Credentials", "true");
        response.setHeader("Access-Control-Allow-Methods", "POST, OPTIONS");
        response.setHeader("Access-Control-Max-Age", "86400");
        response.setHeader("Access-Control-Allow-Headers", "*");
        String method = request.getMethod();
        if (HttpMethod.OPTIONS.toString().equals(method)) {
            response.setStatus(HttpStatus.NO_CONTENT.value());
            return false;
        }
        return true;
    }
}
