pom添加依赖

xml 复制代码

<dependency>
    <groupId>com.alibaba.csp</groupId>
    <artifactId>sentinel-datasource-nacos</artifactId>
</dependency>

添加nacos配置

yaml 复制代码

spring:
  cloud:
    sentinel:
      datasource:
        ds:
          nacos:
            server-addr: 127.0.0.1:8848
            # namespace: public  # 注意public空间下不能显示的设置为public否则获取不到配置
            dataId: sentinel-client-app-sentinel.json
            groupId: DEFAULT_GROUP
            data-type: json
            rule-type: flow

编写Controller测试Sentinel

java 复制代码

@RestController
@RequestMapping("/sentinel/datasource")
public class SentinelDatasourceController {

    @GetMapping("/index")
    @SentinelResource("sentinelDatasourceIndex")
    public String index(){

        return "hello world index" ;
    }
}

nacos中添加dataId为sentinel-client-app-sentinel.json的配置

json 复制代码

[
  {
    "resource": "sentinelDatasourceIndex",
    "limitApp": "default",
    "grade": 1,
    "count": 1,
    "strategy": 0,
    "controlBehavior": 0,
    "clusterMode": false
  }
]

注意如果在namespace为public下创建的配置，则编写配置时namespace必须为空
