zeebe工作流学习总结

环境安装：
1.elasticsearch
2.operate
3.broker

项目启动：
相关API的学习

部署工作流

ZeebeClient client = ZeebeClient.newClientBuilder()
				.brokerContactPoint("192.168.37.101:26500")
				.usePlaintext()
				.build();
System.out.println("connected...");

创建工作流实例

Map<String, Object> params = Maps.newHashMap();
		params.put("orderId", "123456");
		params.put("price", 50);
		WorkflowInstanceEvent workflowInstance = client.newCreateInstanceCommand().bpmnProcessId("order-process").latestVersion().variables(params)
				.send().join();
System.out.println("workflowInstanceKey: " + workflowInstance.getWorkflowInstanceKey());

每一步完成任务

client.newWorker().jobType("have-insurance").handler((jobClient, activatedJob) -> {
			Map<String, Object> params = activatedJob.getVariablesAsMap();
			System.out.println("params: " + params);
			params.put("have-insurance", true);
			jobClient.newCompleteCommand(activatedJob.getKey()).variables(params).variables(params).send().join();
			System.out.println("have-insurance handler job: " + activatedJob.getKey());
		}).open();

发送消息

client.newPublishMessageCommand().messageName("pay-received").correlationKey("123456").send().join();
System.out.println("create pay-received message");

我们可以通过operator查看流程的执行细节，流程每到一处，界面上会有相关图标。
要详细学习zeebe的相关API，需要从具体业务着手，子流程，循环任务，超时回滚流程及异常通知等。
