Sentinel link mode flow control failure solution

  Depend on the introduction of ：

        <!--SpringCloud Alibaba sentinel-datasource-nacos  For subsequent persistence -->
        <dependency>
            <groupId>com.alibaba.csp</groupId>
            <artifactId>sentinel-datasource-nacos</artifactId>
        </dependency>
        <!--SpringCloud Alibaba sentinel -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-sentinel</artifactId>
        </dependency>

my yml To configure ：

spring:
  application:
    name: nacos-provider
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.220.220:8847
      config:
        server-addr: 192.168.220.220:8847
        file-extension: yaml
        group: SAP_GROUP
        namespace: 66a581a0-6a33-4b96-b117-e1bdc0421d85
    sentinel:
      transport:
        port: 8719
        dashboard: 192.168.220.221:8080
      web-context-unify: false

Control layer ：

    @GetMapping(value = "/paymentA")
    public String getPayment2() {
        return paymentService.payment();
    }

    @GetMapping(value = "/paymentB")
    public String getPayment3() {
        return paymentService.payment();
    }

service layer ：

@Service
public class PaymentService {
    @SentinelResource(value = "payment", blockHandler = "fallback")
    public String payment() {
        return "toPayment";
    }
    public String fallback(BlockException ex){
        return "ex";
    }
}

I am here yml Add configuration in web-context-unify: false after , Link mode effective
