SpringCloud: gateway创建全局过滤器

只需增加一个Component类，并实现GloabalFilter接口

package cn.edu.tju.factory;

import org.springframework.cloud.gateway.filter.GatewayFilterChain;
import org.springframework.cloud.gateway.filter.GlobalFilter;
import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import reactor.core.publisher.Mono;

@Component
public class LogFilter implements GlobalFilter {
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        System.out.println("请求路径："+exchange.getRequest().getPath().value());
        return chain.filter(exchange);
    }
}
