Spring Cloud Gateway路由不生效显示404页面

自己搭了个Spring Cloud微服务父子分布式的项目,

图片说明

在搭建Gateway时, 路由始终不生效, 网上几乎所有方法都尝试了,没有用.

图片说明

下面我提供以下几个重点文件, 麻烦大家帮忙找一下问题.
谢谢啦!

1. 请看父项目pom文件

</project>

3. 请查看gateway项目application.yml

server:
  port: 8888
spring:
  application:
    name: gez-gateway #eureka注册实例显示这个名称
  cloud:
    gateway:
      routes:
        - id: search_route
          uri: http://127.0.0.1:8001/
          predicates:
           - Path=/search

    # id 我们自定义的路由ID 保持唯一     注意前面的-,切记不能省略
    # uri 目标服务地址
    # predicates(断言) 路由条件 predicate接受一个输入参数,返回一个布尔值结果,如果断言为真，则路由匹配
    # predicate 组合成其他复杂的逻辑
    # Path前面的-，切记不能省略
#------------------------------------------------EUREKA---------------------------------------------

#eureka注册地址
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8001/eureka,http://localhost:8002/eureka
      #通过ip注册
  instance:
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    hostname: 127.0.0.1

4.请查看gateway项目启动类

@SpringBootApplication(exclude= {DataSourceAutoConfiguration.class})
@EnableEurekaClient
public class SpringBootRun {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootRun.class, args);
    }
}

然后访问http://localhost:8888/search

应该跳转到http://127.0.0.1:8001/

但是却报404页面, 项目中无报错
