Example 1 with GroupWeightConfig

use of org.springframework.cloud.gateway.filter.WeightCalculatorWebFilter.GroupWeightConfig in project spring-cloud-gateway by spring-cloud.

the class WeightCalculatorWebFilterTests method assertWeightCalculation.

    String routeId = route(item);
    filter.addWeightConfig(new WeightConfig(group, routeId, weight));
