This article mainly introduces the integration of spring cloud gateway and sentinel to realize gateway current restriction. The example code is introduced in detail in this article, which has certain reference value for your study or work. You can refer to the following for your friends
Note: sentinel can be used as the current limiting component of each microservice or gateway gateway. Spring cloud gateway has limited flow function, but sentinel is used as a substitute here.
Note: sentinel flow control can be placed on gateway gateway gateway or microserver.
1. Create a child project based on the parent project
2. Add POM dependency
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-gateway</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-sentinel-gateway</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId> </dependency>
2. Add configuration item
server: port: 9092 spring: cloud: nacos: discovery: register-enabled: false server-addr: localhost:8848 namespace: c22e5019-0bee-43b1-b80b-fc0b9d847501 sentinel: transport: dashboard: localhost:8080 port: 8719 scg: fallback: mode: response response-status: 455 response-body: error! gateway: routes: - id: demo_route uri: lb://demo predicates: - Path=/demo/** - id: demo2_test uri: lb://demo2 predicates: - Path=/user/** application: name: gateway-sentinel
Scg.fallback is the response configuration after sentinel current limiting
3. Startup class
4. After startup, gateway sentinel application can be seen in sentinel console, and flow control rules can be set through console.
The above is the whole content of this article. I hope it will help you in your study, and I hope you can support developepaer more.
