问答 定时任务报错：FAIL to create Ioc Bean name=[scheduler]

想在nutz中执行定时任务，
就参照nutzbook中的【为正式开发做准备】的【加入Quartz】一步步操作方法：
加入的jar包是
quartz-2.2.3
nutz-integration-quartz-1.r.59

接下来就是添加修改
conf/quartz.properties

MainModule,修改IocBy

MainSetup类, 添加代码

运行后报错如下：

缺slf4j-api.jar 和 slf4j-log4j12.jar

谢谢，想不到为了个定时任务，需要加入4个jar包

如果你只需要简单的定时任务，可以考虑Tasks类

来自炫酷的 NutzCN

想要做到是：每月1号0点执行一次任务。
刚才试了下，没找到tasks类的例子。
能不能举个简单的tasks类的例子？

看Tasks类的javadoc

不过，既然都配好quartz了，那就用吧😄

来自炫酷的 NutzCN

得，简单的功能需要加4个jar包，估计会被项目经理骂死，还是研究下tasks类

再问下，这个思路有没问题？
在MainSetup的init方法末尾加入
Tasks.scheduleAtFixedRate(new Runnable(){
public void run() {
//检查是否是1号，是就执行。。。
}
}, "2017-06-09 00:00:00", 1, TimeUnit.DAYS); //每天检查1次

恩, 没啥问题

出现了个新的问题：
在定时任务中有执行数据库操作，
在类MainSetup中 已使用
@Inject
protected Dao dao;
在 public void run() {
dao.execute(sql); //报错：Cannot refer to the non-final local variable dao defined in an enclosing scope
}
在这种情况下，定时任务中如何进行数据库操作？

多看文档 http://nutzam.com/core/ioc/ioc_by_hand.html

谢谢，惭愧，文档也看过，但没看得这么仔细。
本来还准备用jdbc直接操作的。。。。
