### 任务监听器TaskListener ###

任务监听器是处理业务逻辑的重要的地方，当任务创建、设定负责人、完成任务时都可以监听的到从而来处理自己的业务。

常用于监听Assignment事件，设置完负责人给负责人发一个消息来通知提示。注意：任务监听器只能用在UserTask上使用。  
监听的事件类型：

*  Create：任务创建后触发。常用于任务创建后设置任务负责人等。
 *  Assignment：任务分配后触发。常用于设置完负责人后向负责人发邮件、短信等通知一下。
 *  Delete：任务完成后触发。
 *  All：所有事件发生都触发。

#### 监听器类 ####

package com.listener;
    
    import org.activiti.engine.delegate.DelegateTask;
    import org.activiti.engine.delegate.TaskListener;
    
    public class MyListener implements TaskListener {
        
    
        @Override
        public void notify(DelegateTask delegateTask) {
        
            System.out.println("delegateTask.getName() = " + delegateTask.getName());
            // create,assignment,delete,all
            System.out.println("delegateTask.getEventName() = " + delegateTask.getEventName());
            // delegateTask.setAssignee("xxx");
        }
    }

当我们发起任务之后，会看到控制台打印如下：

### 流程监听器ExecutionListener ###

任务监听器只能监听UserTask，流程监听器用在流程的不同的阶段上：

*  开始事件和结束事件的开始和结束
 *  经过输出顺序流
 *  流程活动的开始和结束
 *  流程网关的开始和结束
 *  中间事假的开始和结束

#### 监听器类 ####

package com.listener;
    
    import org.activiti.engine.delegate.DelegateExecution;
    import org.activiti.engine.delegate.ExecutionListener;
    
    public class MyExecutionListener implements ExecutionListener {
        
        @Override
        public void notify(DelegateExecution execution) {
        
            System.out.println("execution.getCurrentFlowElement().getId() = " + execution.getCurrentFlowElement().getId());
            System.out.println("execution.getCurrentFlowElement().getName() = " + execution.getCurrentFlowElement().getName());
            System.out.println("execution.getEventName() = " + execution.getEventName());
            System.out.println("execution.getProcessDefinitionId() = " + execution.getProcessDefinitionId());
            System.out.println("execution.getProcessInstanceId() = " + execution.getProcessInstanceId());
        }
    }

当发起流程控制台输出如下：
