在Webflux WebFilter的最后执行一些逻辑

import org.springframework.core.Ordered;
import org.springframework.http.HttpStatus;

import org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;

import reactor.core.publisher.Mono;

@Component
public class MyWebFilter implements WebFilter, Ordered {

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        // 在这里可以对请求进行处理或修改
        ServerHttpRequest request = exchange.getRequest();
        ServerHttpResponse response = exchange.getResponse();

        // 调用chain.filter继续处理请求
        return chain.filter(exchange).then(Mono.fromRunnable(() -> {
            // 在这里可以对响应进行处理或修改
            HttpStatus status = response.getStatusCode();
            if (status.isError()) {
                // 处理错误响应
            } else {
                // 处理正常响应
            }
        }));
    }

    @Override
    public int getOrder() {
        // 设置过滤器的执行顺序，数字越小越先执行
        return Ordered.LOWEST_PRECEDENCE;
    }
}
