@SpringBootApplication
@EnableZuulProxy
public class ApiGatewayApplication {

    public static void main(String[] args) {
        SpringApplication.run(ApiGatewayApplication.class, args);
    }

    @ConfigurationProperties("zuul")
    @RefreshScope
    public ZuulProperties zuulProperties(){
        return new ZuulProperties();
    }

}

这个少@Bean吧,没有@Bean应该不会到spring容器里,这段代码应该不生效吧,这个应该加上@Bean,换个名字,再加@primary注解这样应该能先于默认的ZuulProperties被Zuul相关的配置类读到吧
