网关被扫描后会注册四个核心配置类，当然在配置类中仍然有各种流程中需要的bean后面会详细解释。
l GatewayAutoConfiguration 网关基础配置类，当中承载着核心的配置逻辑
l GatewayClassPathWarningAutoConfiguration 网关类加载配置类，就是用于校验是否加载的时webFlux依赖，而不是普通的web依赖。
l GatewayLoadBalancerClientAutoConfiguration 网关客户端负载均衡配置类
l GatewayRedisAutoConfiguration 网关限流器配置类
我们先回过头，假如你已经搭建了一个gateway的demo，那么在网关中进行负载均衡，会添加注解如下：
@RibbonClient(name = "pay-server", configuration = {IRule2.class})
@Configuration @ConditionalOnClass({LoadBalancerClient.class, RibbonAutoConfiguration.class, DispatcherHandler.class}) @AutoConfigureAfter(RibbonAutoConfiguration.class) public class GatewayLoadBalancerClientAutoConfiguration { // GlobalFilter beans @Bean @ConditionalOnBean(LoadBalancerClient.class) public LoadBalancerClientFilter loadBalancerClientFilter(LoadBalancerClient client) { return new LoadBalancerClientFilter(client); } }
RibbonClientConfigurationRegistrar
private void registerClientConfiguration(BeanDefinitionRegistry registry, Object name, Object configuration) { BeanDefinitionBuilder builder = BeanDefinitionBuilder .genericBeanDefinition(RibbonClientSpecification.class); builder.addConstructorArgValue(name); builder.addConstructorArgValue(configuration); registry.registerBeanDefinition(name + ".RibbonClientSpecification", builder.getBeanDefinition()); }
