本博客参考gitee开源项目代码结合自己的理解记录下微服务场景下的使用。

这里使用eureka作为注册中心,person和equipment两个web服务作为业务中台本例中会使用postman调用person服务person服务中调用equipment服务。

依赖equipment-apiequipment-provider

eureka的实例名称client:registerWithEureka:

false表示当前项目不以客户端注册到服务中心(因为该项目本身就是注册中心)fetchRegistry:

利用postman访问localhost:8002/person/get其中body中id传不同参数进行测试
