***

## 1、工程结构如下
- account-service，账号服务，分别调用address-service(Dubbo)，payment-service(Fegin)
- address-service，地址服务
- payment-service，支付服务
- sample-gateway，服务网关，代理account-service和payment-service，支持全局日志、鉴权
- nacos，同github下载、编译结果，github下载较慢
- sentinel-dashboard.jar，同github下载、编译结果，github下载较慢

## 2、启动服务

### 1）启动nacos

```
cd alibaba-sample/nacos/bin/
sh startup.sh -m standalone
```

访问地址：http://localhost:8848/nacos  
账号：nacos  
密码：nacos  

增加配置 nacos -> 配置管理 -> 配置列表 -> +

    "maxQueueingTimeMs": 20000,
    "count": 1,
    "grade": 1,
    "limitApp": "default",
    "strategy": 0
  }
]
```
#### account-service-degrade-rules

    "resource": "GET:http://payment-service/pay/balance",
    "count": 500,
    "grade": 0,
    "timeWindow": 10
  }
]
```
#### gateway-router
Data ID：gateway-router  
Group：DEFAULT_GROUP

配置内容：
```
[{
    "id": "account-router",
    "order": 0,
    "predicates": [{
        "args": {
            "pattern": "/account/**"
        }, 
        "name": "Path"
    }],
    "uri": "lb://account-service"
}, 
{
    "id": "payment-router",
    "order": 0,
    "predicates": [{
        "args": {
            "pattern": "/pay/**"
        }, 
        "name": "Path"
    }],
    "uri": "lb://payment-service"
}]
```

### 2）启动sentinel

```
cd alibaba-sample/

```

查看 nacos -> 服务管理 -> 服务列表，payment-service已经注册上

测试连通性：  
http://localhost:8082/pay/balance?id=1  
http://localhost:8083/pay/balance?id=1
