#  springcloud-alibaba-project-demo

#### 介绍
- springcloud-alibaba微服务最小系统
- 集成了springcloud-alibaba五大核心组件,不包含其他第三方包

### 实现的功能demo
- openfeign服务远程调用
- sentinel限流测试
- gateway网关、跨域配置等
- nacos的服务注册与发现
- nacos作为微服务的配置中心

#### 软件架构(环境)
- jdk: 1.8
- maven: 3.5.2
- nacos-2.0.3: 注册中心-配置中心
- gateway: 微服务网关
- openfeign: 服务远程调用
- sentinel-1.8.4: 熔断,限流,服务保护等

## nacos上等相关配置
##### order服务
- dataId: cloud-order-dev.yaml
- Group: DEV_GROUP
```yaml
server:
  port: 8081
spring:
  application:
    name: cloud-order
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
        namespace: 0d497b0f-19fe-47f3-a5d0-6499c698841a
        group: DEV_GROUP
    sentinel:
      transport:
        dashboard: localhost:8089
      eager: true
feign:
  sentinel:
    enabled: true
```
##### user服务
- dataId: cloud-user-dev.yaml
- Group: DEV_GROUP
```yaml
server:
  port: 8082
spring:
  application:
    name: cloud-user
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848

      eager: true
feign:
  sentinel:
    enabled: true
```
##### gateway
- dataId: cloud-gateway-dev.yaml
- Group: DEV_GROUP
```yaml
