1，摒除WebMvc 依赖。
<exclusions> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </exclusion> <exclusion> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat?undertow</artifactId> </exclusion> </exclusions>
2，添加WebFlux依赖
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-gateway</artifactId> </dependency> //spring-cloud-starter-gateway 内置 spring-boot-starter-webflux，所以直接引用就好了
3，引入组件集成的其他依赖。以下代码为作者这边的情况
<!-- Nacos --> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId> </dependency> <!--Hystrix--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-hystrix</artifactId> <exclusions> <exclusion> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> </exclusion> </exclusions> </dependency>
Spring Cloud Alibaba Sidecar 模式使用 【WebFlux、Netty】
