如何在spring集成中模拟出站网关

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-gateway</artifactId>
</dependency>

spring:
  cloud:
    gateway:
      routes:
        - id: outbound_route
          uri: http://example.com  # 模拟的出站网关地址
          predicates:
            - Path=/outbound/**  # 匹配的请求路径

spring.cloud.gateway.routes[0].id=outbound_route
spring.cloud.gateway.routes[0].uri=http://example.com
spring.cloud.gateway.routes[0].predicates[0]=Path=/outbound/**

@SpringBootApplication
@EnableGateway
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
