如何在Spring WebFlux中以编程方式配置请求上下文属性

import org.springframework.stereotype.Component;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;

@Component
public class RequestContextFilter implements WebFilter {

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        // 添加自定义属性到请求上下文
        exchange.getAttributes().put("customAttribute", "someValue");

        // 继续处理请求链
        return chain.filter(exchange);
    }
}

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

@Component
public class RequestContextFilter implements WebFilter {

    private static final Logger logger = LoggerFactory.getLogger(RequestContextFilter.class);

    @Override
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        exchange.getAttributes().put("customAttribute", "someValue");
        logger.info("customAttribute set to: {}", exchange.getAttribute("customAttribute"));

        return chain.filter(exchange);
    }
}
