Java Activiti(8)--監聽器

一、執行監聽器

1、創建監聽

/**
 * 執行監聽器
 * Created by Administrator on 2017/10/12.
 */
public class MyExecutionListener implements ExecutionListener {
    @Override
    public void notify(DelegateExecution execution) {
        System.out.println("notify====getEventName=====" + execution.getEventName());
    }
}

2、創建流程：

3、在start處添加監聽

4、生成三個文件

5、部署流程

 @Test
    public void deployLeave() throws Exception {
        DeploymentBuilder builder = processEngine.getRepositoryService().createDeployment();
        builder.addClasspathResource("flow/executionListener.bpmn");
        builder.addClasspathResource("flow/executionListener.png");
        builder.name("執行監聽器報銷流程部署");
        Deployment deploy = builder.deploy();
        System.out.println("deploy.getId()==" + deploy.getId());
    }

6、啓動流程實例時,添加變量

@Test
    public void startProcessInstanceByKey() throws Exception {
        //String processDefinitionKey = "grouptask";
        String processInstanceId = "72501";
        Map<String, Object> variable = new HashMap<String, Object>();
        variable.put("amount", "300元");
        variable.put("reason", "出差");
        ProcessInstance processInstance = processEngine.getRuntimeService().startProcessInstanceById(processInstanceId,variable);
        System.out.println("processInstance.getId()===" + processInstance.getId());
        System.out.println("processInstance.getProcessDefinitionId()===" + processInstance.getProcessDefinitionId());
    }

7、完成任務

@Test
    public void dealPersonalTask() throws Exception {
        String taskId = "75011";
        processEngine.getTaskService().complete(taskId);
    }

注：在提交任務與完成任務時，都會觸發監聽事件

二、任務監聽器

1、創建監聽器

public class MyTaskListener1 implements TaskListener {
    @Override
    public void notify(DelegateTask delegateTask) {
        System.out.println(delegateTask.getExecutionId());
        Map<String, Object> variables = delegateTask.getVariables();
        Set<String> variableNames = delegateTask.getVariableNames();
        for(String key : variableNames){
            System.out.println(key +":" + delegateTask.getVariable(key));
        }
        System.out.println("一個任務由" + delegateTask.getName() + "創建了,下一步由" + delegateTask.getAssignee() + "負責辦理");
    }
}

2、添加create監聽器
