这两个是类：
public class LoginAdminGatewayFilter implements GatewayFilter, Ordered {

private static final Logger LOG = LoggerFactory.getLogger(LoginAdminGatewayFilter.class);

@Resource
private RedisTemplate redisTemplate;

@Override
public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
    LOG.info( "token拦截开始...." );
    //获取header的token参数
    String token = exchange.getRequest().getHeaders().getFirst("token");
    LOG.info("控台登录验证开始，token：{}", token);
    return chain.filter(exchange);
}

@Override
public int getOrder()
{
    return 1;
}

}

public class LoginAdminGatewayFilterFactory extends AbstractGatewayFilterFactory {

@Resource
LoginAdminGatewayFilter loginAdminGatewayFilter;

@Override
public GatewayFilter apply(Object config) {
    return loginAdminGatewayFilter;
}

}

依赖如下：


org.springframework.cloud
spring-cloud-starter-gateway

   <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>

    <dependency>
        <groupId>com.alibaba</groupId>

    <!-- 热部署DevTools -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-devtools</artifactId>
    </dependency>
</dependencies>

gateway的控制台打印如下：

页面上面Console有打印：
请求headers增加token: kjvHGWIR

Network里面的list请求，Request headers里面有：
token:kjvHGWIR

但是就是gateway没有打印LOG日志，不知道为什么？
