This topic describes how to use the SDK for Java to query all event buses.

Sample code:

import com.aliyun.eventbridge.EventBridge;
import com.aliyun.eventbridge.EventBridgeClient;
import com.aliyun.eventbridge.models.Config;
import com.aliyun.eventbridge.models.ListEventBusesRequest;
import com.aliyun.eventbridge.models.ListEventBusesResponse;

public class listEventBusSample {

    private EventBridge eventBridgeClient;

    public listEventBusSample()  {
        Config authConfig = new Config();
        authConfig.accessKeyId = "{accessKeyId}";// The AccessKey ID for identity authentication. You can create AccessKey IDs in the RAM console. For more information about how to obtain the ID, see Obtain an AccessKey pair. 
        authConfig.accessKeySecret = "{accessKeySecret}";// The AccessKey secret for identity authentication. You can create AccessKey secrets in the RAM console. For more information about how to obtain the secret, see Obtain an AccessKey pair. 
        authConfig.endpoint = "{endpoint}";// The endpoint. For more information, see Regions and endpoints. 
        eventBridgeClient = new EventBridgeClient(authConfig);
    }

    public void listEventBusSample() {
        try {
            ListEventBusesRequest listEventBusesRequest = new ListEventBusesRequest();
            ListEventBusesResponse response = eventBridgeClient.listEventBuses(listEventBusesRequest);
            System.out.println("list bus success : " + response);
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args)  {
        listEventBusSample sample = new listEventBusSample();
        try {
            sample.listEventBusSample();
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }
}
