gateway integration

[levin950825]

使用最新版本Spring Boot，然后网关结合官方案例结果不符合预期结果，是版本造成的BUG还是我配置有误？
Use the latest version of spring boot, and the gateway combined with the official case results do not meet the expected results. Is the bug caused by the version or am I misconfigured?

Which Component
eg. Nacos Discovery, Sentinel
