activiti7.0工作流，举个例子实现自定义任务监听和执行监听代码

public class MyListener implements TaskListener, ExecutionListener {

	// 实现任务监听TaskListener
    @Override
    public void notify(DelegateTask delegateTask) {
        log.info("自定义任务监听器执行");
        String eventName = delegateTask.getEventName();
        switch (eventName){
            case EVENTNAME_CREATE:
                log.info("===create===");
                create(delegateTask);
                break;
            case EVENTNAME_ASSIGNMENT:
                log.info("===assignment===");
                assigment(delegateTask);
                break;
            case EVENTNAME_COMPLETE:
                log.info("===complete===");
                complete(delegateTask);
                break;
            case EVENTNAME_DELETE:
                log.info("===delete===");
                delete(delegateTask);
                break;
            default:
                break;
        }
    }

    public void create(DelegateTask delegateTask){}

    public void assigment(DelegateTask delegateTask){}

	// 任务监听完成事件
    public void complete(DelegateTask delegateTask){
		Integer operateFlag = (Integer)delegateTask.getVariableLocal("operateFlag");
        log.info("operateFlag:{}",operateFlag);
        Workflow workflow = new Workflow();
        workflow.setInstanceId(delegateTask.getProcessInstanceId());
        // 修改状态
        workflowMedia.setStatus(AuditStatus.Audit.getCode());
		SpringUtils.getBean(IWorkflowService.class).updateWorkflow(workflowMedia);
        }
	}

    public void delete(DelegateTask delegateTask){}

	// 实现执行监听ExecutionListener
    @Override
    public void notify(DelegateExecution delegateExecution) {
        log.info("自定义执行监听器执行");
        String eventName = delegateExecution.getEventName();
        switch (eventName) {
            case EVENTNAME_START:
                log.info("===start===");
                start(delegateExecution);
                break;
            case EVENTNAME_END:
                log.info("===end===");
                end(delegateExecution);
                break;
            case EVENTNAME_TAKE:
                log.info("===take===");
                take(delegateExecution);
                break;
            default:
                break;
        }
    }

    private void start(DelegateExecution delegateExecution) {}

    private void end(DelegateExecution delegateExecution) {}

    private void take(DelegateExecution delegateExecution) {}
