通过 @Inject 注入，而不是继承

怎样才能让定时任务调用的时候不把dao对象传到service方法内，就直接保证有dao对象

qq_39fcc7a4 3楼•1928天前

注入CwDisbursementVoucherService 么？

是的, 直接new是必须死

这个解决了，但是有一个新的问题，在调用activiti的claim方法时，我们自己写的ActivitiUserTaskActivityBehavior类继承了activiti的UserTaskActivityBehavior类，里面获取Ioc获取不到。

public class ActivitiUserTaskActivityBehavior extends UserTaskActivityBehavior {

	Ioc ioc = Mvcs.getIoc();
	XtWorkFlowTaskService xtWorkFlowTaskService = ioc.get(XtWorkFlowTaskService.class);

	public ActivitiUserTaskActivityBehavior(String userTaskId, TaskDefinition taskDefinition) {
		super(userTaskId, taskDefinition);
	}

把ioc的文档看一遍

qq_39fcc7a4 7楼•1928天前

您的意思是这个类也需要加@IocBean注解是吧,但是还是不行，请大佬教我下吧

qq_39fcc7a4 8楼•1928天前

以为我这边正常调用是没问题的，但是定时任务调用就会有问题获取不到。

手动获取ioc对象，看这个

这个应该属于非MVC下，我是通过new的方法，但是这样太慢了，都扫描了5分钟还没好

new毛线呀，用setup的init方法放到静态变量去
