Quick start with SpringCloud

This document introduces how to quickly access the Soul Gateway using SpringCloud. You can get the code example of this document by clicking here.

Environment to prepare#

Please refer to the setup and launch soul-admin and soul-bootstrap.

  • Add the following dependencies to the soul-bootstrap's pom.xml file:
<!--soul springCloud plugin start-->dependency>    <groupId>org.dromara</groupId>    <artifactId>soul-spring-boot-starter-plugin-springcloud</artifactId>    <version>${project.version}</version></dependency><dependency>    <groupId>org.springframework.cloud</groupId>    <artifactId>spring-cloud-commons</artifactId>    <version>2.2.0.RELEASE</version></dependency><dependency>    <groupId>org.springframework.cloud</groupId>    <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>    <version>2.2.0.RELEASE</version></dependency>
<!-- If using Eureka as a registry needs to be introduced --><dependency>    <groupId>org.springframework.cloud</groupId>    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>    <version>2.2.0.RELEASE</version></dependency>
<!--soul springCloud plugin start end-->

Startup the soul-bootstrap project

Run the soul-examples-springcloud and soul-examples-eureka project#

In the example project we use eureka as the SpringCloud registry

Download soul-examples-eureka and soul-examples-springcloud

  1. Startup the Eureka service

Execute the org.dromara.soul.examples.eureka.EurekaServerApplication main method to start project.

  1. Startup the Spring Cloud service

Execute the org.dromara.soul.examples.springcloud.SoulTestSpringCloudApplication main method to start project.

The following log appears when the startup is successful:

Enable the springCloud plugin#

  • enabled the springCloud plugin in the soul-admin plugin management.

Testing http request#

The soul-examples-springcloud project will automatically register interface methods annotated with @SoulSpringCloudClient in the soul gateway after successful startup.

Open Plugin Management -> springcloud to see the list of plugin rule configurations

Use PostMan to simulate HTTP to request your SpringCloud service
