如何在Java配置中添加自定义spring云网关过滤器？

import org.springframework.cloud.gateway.filter.GatewayFilter;
import org.springframework.cloud.gateway.filter.factory.AbstractGatewayFilterFactory;
import org.springframework.stereotype.Component;

@Component
public class CustomFilter extends AbstractGatewayFilterFactory<CustomFilter.Config> {

    public CustomFilter() {
        super(Config.class);
    }

    @Override
    public GatewayFilter apply(Config config) {
        // 在这里编写自定义过滤器的逻辑
        return (exchange, chain) -> {
            // 过滤器逻辑处理
            return chain.filter(exchange);
        };
    }

    public static class Config {
        // 这里可以定义一些配置参数
    }
}

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class GatewayConfig {

    @Bean
    public CustomFilter customFilter() {
        return new CustomFilter();
    }
}

spring:
  cloud:
    gateway:
      routes:
        - id: custom_route
          uri: http://example.com
          filters:
            - customFilter=param1,value1,param2,value2
