Spring Cloud Gateway is a new project within Spring Cloud designed for creating API gateways. Built on Spring 5, it utilizes reactive programming to offer a simple and efficient method for routing and filtering requests.

To use Spring Cloud Gateway, you need to follow the steps below:

  1. Add dependencies: In your project, include the dependencies for Spring Cloud Gateway. You can add the following dependencies in your Maven or Gradle build file.
  2. Maven: Expert or skilled person.


  3. org.springframework.cloud
    spring-cloud-starter-gateway

  4. Using Gradle:
  5. dependencies {
    implement ‘org.springframework.cloud:spring-cloud-starter-gateway’
    }
  6. Set up routing: Configure the routes you want to use in the application’s configuration file. This can be done through YAML or property files.
  7. Example YAML configuration:
  8. spring:
    cloud:
    gateway:
    routes:
    – id: my_route
    uri: http://example.com
    conditions:
    – Path=/my-service/**
  9. Example property configuration:
  10. The route with the ID “my_route” is directing traffic to http://example.com, based on the predicate that the path starts with /my-service/.
  11. Run the application: Start your Spring Boot application and access the configured routes. Your application will route requests to the specified URI and filter and forward them according to the set routing rules.

These are just the basic steps for using Spring Cloud Gateway, you can also configure more advanced features like dynamic routing, global filters, etc. For more detailed information, please refer to the official documentation of Spring Cloud Gateway.
