Examples with JsonCloudEventData io.cloudevents.jackson.JsonCloudEventData used on opensource projects

Example 1 with JsonCloudEventData

use of io.cloudevents.jackson.JsonCloudEventData in project samples-java by temporalio.

the class Starter method main.

public static void main(String[] args) {
    WorkflowServiceStubs service = WorkflowServiceStubs.newInstance();
    // Add CloudEventsPayloadConverter
    // It has the same encoding type as JacksonJsonPayloadConverter
    DefaultDataConverter ddc = DefaultDataConverter.newDefaultInstance().withPayloadConverterOverrides(new CloudEventsPayloadConverter());
    WorkflowClientOptions workflowClientOptions = WorkflowClientOptions.newBuilder().setDataConverter(ddc).build();
    WorkflowClient client = WorkflowClient.newInstance(service, workflowClientOptions);
    WorkerFactory factory = WorkerFactory.newInstance(client);
    Worker worker = factory.newWorker(TASK_QUEUE);
    worker.registerWorkflowImplementationTypes(CEWorkflowImpl.class);
    factory.start();
    WorkflowOptions newCustomerWorkflowOptions = WorkflowOptions.newBuilder().setTaskQueue(TASK_QUEUE).build();
    CEWorkflow workflow = client.newWorkflowStub(CEWorkflow.class, newCustomerWorkflowOptions);
    // Create 10 cloud events
    List<CloudEvent> cloudEventList = new ArrayList<>();
    for (int i = 0; i < 10; i++) {
        cloudEventList.add(CloudEventBuilder.v1().withId(String.valueOf(100 + i)).withType("example.demo").withSource(URI.create("http://temporal.io")).withData("application/json", ("{\n" + "\"greeting\": \"hello " + i + "\"\n" + "}").getBytes(Charset.defaultCharset())).build());
    }
    WorkflowClient.start(workflow::exec, cloudEventList.get(0));
    // Send signals (cloud event data)
    for (int j = 1; j < 10; j++) {
        workflow.addEvent(cloudEventList.get(j));
    }
    // Get the CE result and get its data (JSON)
    String result = ((JsonCloudEventData) workflow.getLastEvent().getData()).getNode().get("greeting").asText();
    System.out.println("Last event body: " + result);
    System.exit(0);
}

Example 2 with JsonCloudEventData

use of io.cloudevents.jackson.JsonCloudEventData in project samples-java by temporalio.

the class CloudEventsPayloadConverterTest method testActivityImpl.

@Test
public void testActivityImpl() {
    List<CloudEvent> cloudEventList = new ArrayList<>();
    for (int i = 0; i < 10; i++) {
        cloudEventList.add(CloudEventBuilder.v1().withId(String.valueOf(100 + i)).withType("example.demo").withSource(URI.create("http://temporal.io")).withData("application/json", ("{\n" + "\"greeting\": \"hello " + i + "\"\n" + "}").getBytes(Charset.defaultCharset())).build());
    }
    WorkflowOptions workflowOptions = WorkflowOptions.newBuilder().setTaskQueue(testWorkflowRule.getTaskQueue()).build();
    CEWorkflow workflow = testWorkflowRule.getWorkflowClient().newWorkflowStub(CEWorkflow.class, workflowOptions);
    // start async
    WorkflowClient.start(workflow::exec, cloudEventList.get(0));
    for (int j = 1; j < 10; j++) {
        workflow.addEvent(cloudEventList.get(j));
    }
    // Get the CE result and get its data (JSON)
    String result = ((JsonCloudEventData) workflow.getLastEvent().getData()).getNode().get("greeting").asText();
    assertNotNull(result);
    assertEquals("hello 9", result);
