Example 1 with ProviderAPI

use of com.tencent.polaris.api.core.ProviderAPI in project polaris-java by polarismesh.

the class CircuitBreakExample method main.

public static void main(String[] args) throws Throwable {

        // 1. 先注册服务实例
        registerInstances(providerAPI, initResult);
        // 2. 获取可用的服务实例列表

        System.out.println("available instances count is " + availableInstances.length);
        // 3. 针对某个服务实例上报调用结果失败，默认连续10次失败，或者1分钟错误率50%，就会对实例进行熔断

            CircuitBreakExampleUtils.doSleep(500);

        // 4. 判断服务实例是否还在可用列表中，已经熔断的实例是不会再次返回
        availableInstances = getAvailableInstances(consumerAPI, initResult);
        System.out.println("available instances count is " + availableInstances.length);
        for (Instance instance : availableInstances) {
