Spring Cloud 服务接入到 Apache ShenYu 网关完整案例-开发者社区

Spring Cloud快速开始

本文档演示如何将Spring Cloud服务接入到Apache ShenYu网关。您可以直接在工程下找到本文档的示例代码。

环境准备

请参考运维部署的内容，选择一种方式启动shenyu-admin。比如，通过本地部署启动Apache ShenYu后台管理系统。

启动网关，如果是通过源码的方式，直接运行shenyu-bootstrap中的ShenyuBootstrapApplication。

启动顺序

启动shenyu-admin
启动shenyu-bootstrap
启动注册中心，例如shenyu-examples下的eureka项目
配置shenyu-examples-springcloud注册发现

shenyu:discovery:enable:truetype:eurekaserverList:${eureka.client.serviceUrl.defaultZone}registerPath:${spring.application.name}props:nacosNameSpace:ShenyuRegisterCenter

运行`shenyu-examples-springcloud`

示例项目中我们使用eureka作为Spring Cloud的注册中心。你可以使用本地的eureka，也可以使用示例中提供的应用。

下载 shenyu-examples-eureka 、shenyu-examples-springcloud .

启动eureka服务，运行org.apache.shenyu.examples.eureka.EurekaServerApplicationmain方法启动项目。

启动spring cloud服务，运行org.apache.shenyu.examples.springcloud.ShenyuTestSpringCloudApplicationmain方法启动项目。

成功启动会有如下日志：
