註：spring-cloud-starter-gateway和spring-boot-starter-web依賴發生沖突，因為gateway依賴包內置spring-boot-starter-webflux依賴，與web包內的spring-boot-starter-webflux依賴起瞭沖突。

解決方法

將spring-boot-starter-webspring-依賴包剔除，或剔除boot-starter-webflux依賴包。

1. 剔除web包
<!-- gateway與spring-boot-starter-web沖突(spring-boot-starter-webflux) -->
<!--<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-web</artifactId>
</dependency>-->
1. 剔除webflux包
<!-- gateway與spring-boot-starter-web沖突(spring-boot-starter-webflux) -->
<dependency>
     <groupId>org.springframework.boot</groupId>
     <artifactId>spring-boot-starter-web</artifactId>     <exclusions>          <exclusion>               <groupId>org.springframework.boot</groupId>               <artifactId>spring-boot-starter-webflux</artifactId>          </exclusion>     </exclusions></dependency>
