server:
port: 8700
spring:
application:
name: sca-gateway
cloud:
gateway:
routes: #配置网关路由规则
- id: route01 #路由id,自己指定一个唯一值即可
uri: http://localhost:8081/ #网关帮我们转发的url
predicates: ###断言(谓此):匹配请求规则
- Path=/nacos/provider/echo/** #请求路径定义,此路径对应uri中的资源
filters: ##网关过滤器,用于对谓词中的内容进行判断分析以及处理
- StripPrefix=1 #转发之前去掉path中第一层路径,例如nacos

注:spring-cloud-starter-gateway
和spring-boot-starter-web
依赖发生冲突,因为gateway依赖包内置spring-boot-starter-webflux
依赖,与web包内的spring-boot-starter-webflux
依赖起了冲突。
解决方法
将spring-boot-starter-webspring-
依赖包剔除,或剔除boot-starter-webflux
依赖包。
1. 剔除web包
<!-- gateway与spring-boot-starter-web冲突(spring-boot-starter-webflux) -->
<!--<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>-->
1. 剔除webflux包
<!-- gateway与spring-boot-starter-web冲突(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>
