Examples with QuotaRequest com.tencent.polaris.ratelimit.api.rpc.QuotaRequest used on opensource projects

Example 1 with QuotaRequest

use of com.tencent.polaris.ratelimit.api.rpc.QuotaRequest in project polaris-java by polarismesh.

the class RateLimitExample method main.

public static void main(String[] args) throws Exception {
    InitResult initResult = LimitExampleUtils.initRateLimitConfiguration(args);
    String namespace = initResult.getNamespace();
    String service = initResult.getService();
    int concurrency = initResult.getConcurrency();
    ScheduledExecutorService executorService = Executors.newScheduledThreadPool(concurrency);
    // 注意：使用本地限流时，限流阈值计数器会存放在LimitAPI实例内部，无法跨实例共享，因此LimitAPI建议通过进程单例模式使用
    try (LimitAPI limitAPI = LimitAPIFactory.createLimitAPI()) {
        Runnable runnable = new Runnable() {

            @Override
            public void run() {
                QuotaRequest quotaRequest = new QuotaRequest();
                quotaRequest.setNamespace(namespace);
                quotaRequest.setService(service);
                quotaRequest.setMethod("echo");
                quotaRequest.setCount(1);
                QuotaResponse quotaResponse = limitAPI.getQuota(quotaRequest);
                System.out.println("quotaResponse is " + quotaResponse.getCode());
