我需要在早上 7 点 5 分执行一项任务,但出现错误。这是我创建的控制器。
@Service("myCtr")
public class MyController {
@Autowired
private TaskScheduler scheduler;
@Async
public void executeTaskT() {
scheduler.schedule(new MyWorker(),
new CronTrigger("5 7 * * *"));
}
}
MyWorker 就是这样实现 Runnable 的:
[...]
@Override
public void run() {
doWork();
}
private void doWork() { [...]
我的调度程序配置文件由 web-application-config.xml 导入:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd">
<bean id="TaskScheduler"
class="org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler">
<property name="waitForTasksToCompleteOnShutdown" value="true" />
<property name="poolSize" value="1000" />
</bean>
</beans>
错误:
