Activiti的环节监听tasklistener中注入spring bean

项目地址：activiti-workflow
类实现TaskListener，采用@Service注解，确保此类可以被Spring的自动扫描的到。

@Service("taskExpressionService")
public class TaskExpressionService implements TaskListener {

    @Autowired
    private UserServiceImpl userService;

    @Override
    public void notify(DelegateTask delegateExecution) {
        String eventName = delegateExecution.getEventName();
        if ("create".endsWith(eventName)) {
            System.out.println("create=========");
        }else if ("assignment".endsWith(eventName)) {
            System.out.println("assignment========"+delegateExecution.getAssignee());
        }else if ("complete".endsWith(eventName)) {
            System.out.println("complete===========");
        }else if ("delete".endsWith(eventName)) {
            System.out.println("delete=============");
        }

    }
}

环节里这样配置就可以注入Spring的bean.
