JBPM 6 - 1.6 - Triggering Process via REST 通过REST触发流程

The workbench contains an execution server (for executing processes and tasks), which also allows you to invoke various process and task related operations through a remote API. As a result, you can setup your process engine "as a service" and integrate this into your applications easily by doing remote requests and/or sending the necessary triggers to the execution server whenever necessary (without the need to embed or manage this as part of your application).

workbench包括一个执行服务区（用于执行流程和任务），它也允许你启动各种通过远程接口进行的操作的流程和任务。这样做的结果就是，你能把你的流程引擎设置为“服务”，轻松地集成到你的应用里面，实现起来是通过进行远程请求，并且/或者在必要时向执行服务器发送必要的触发指令（triggers）（这样做可以避免将它们作为你的应用的一部分，而必然要嵌入或者管理它们。）

Scenario 场景

  • You want to execute your process stored in Workbench externaly injecting process variables
？？
  • In our case we want to start recruitment process when a new person applies
我们的情况是，我们需要在新人应聘时启动招聘流程

Documentation 文档

Getting deploymentId

  • Via REST service
POST:http://localhost:8080/jbpm-console/rest/deployment
Accept: application/json
  • Using Workbench
    • Authoring / Project Authoring
    • Tools / Project Editor

Java Remote API

 URL baseUrl = new URL("http://localhost:8080/jbpm-console");
 String user = "krisv";
 String password = "krisv";
 String deploymentId = "hrproj:hrproj:1.0";

 RemoteRestRuntimeFactory restSessionFactory	= new RemoteRestRuntimeFactory(deploymentId, baseUrl, user, password);
 RuntimeEngine engine = restSessionFactory.newRuntimeEngine();
 KieSession ksession = engine.getKieSession();
 ProcessInstance processInstance = ksession.startProcess("hrproj.emp_recruitmen2");
 long procId = processInstance.getId();
 String taskUserId = user;
 TaskService taskService = engine.getTaskService();
 
 List<TaskSummary> tasks = taskService.getTasksAssignedAsPotentialOwner("krisv", "en-UK");
 
 long taskId = -1;
 
 for (TaskSummary task : tasks) {
 	if (task.getProcessInstanceId() == procId) {
  taskId = task.getId();
 	}
 }

 if (taskId == -1) {
 	throw new IllegalStateException("Unable to find task for " + user
  	+ " in process instance " + procId);
 }

 taskService.start(taskId, taskUserId);
