</project>

2.添加启动类 GateWayApplication.java

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

3.application.yml

server:
  port: 88

spring:
  cloud:
    gateway:
      routes:
        - id: query_route
          uri: https://baidu.com
          filters:
            - StripPrefix=1
          predicates:
            - Query=url,green

4.运行项目 并输入地址 http://localhost:88/test?url=green 并可以正确跳转到baidu.com

如果遇到如下问题

 则需要在添加

 filters:
   - StripPrefix=1 即可正确跳转
