就把以前写过的配置文件模板直接复制过来,又顺手点进去看了一下源码,发现TimerFactoryBean、ScheduledTimerTask都已经被标记成@Deprecated了
- @Deprecated
- public class TimerFactoryBean implements FactoryBean<Timer>, BeanNameAware, InitializingBean, DisposableBean
@Deprecated
public class TimerFactoryBean implements FactoryBean<Timer>, BeanNameAware, InitializingBean, DisposableBean
- @Deprecated
- public class ScheduledTimerTask
@Deprecated
public class ScheduledTimerTask
那肯定就不乐意用了,就上网找了找spring3.0之后的新用法,果然是有变化,而且比以前简单了很多,在这里记录一下
我记得以前那种做法,业务类是要继承自TimerTask才行的,现在就不用了,是一个pojo就可以
- public class TestService {
- private Logger logger = LoggerFactory.getLogger(TestService.class);
- public void sayHello() {
- System.out.println("hello world");
- }
- public void sayBye() {
- System.out.println("bye world");
- }
- }
public class TestService {
private Logger logger = LoggerFactory.getLogger(TestService.class);
public void sayHello() {
System.out.println("hello world");
}
public void sayBye() {
System.out.println("bye world");
}
}
然后配置文件也更简单
- <beans xmlns="http://www.springframework.org/schema/beans"
- xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task"
- xsi:schemaLocation="http://www.springframework.org/schema/beans
- http://www.springframework.org/schema/beans/spring-beans.xsd
- http://www.springframework.org/schema/task
- http://www.springframework.org/schema/task/spring-task-3.0.xsd">
- <bean id="testService" class="com.xxx.spring.business.TestService" />
- <task:scheduled-tasks>
- <task:scheduled ref="testService" method="sayHello" cron="3/11 * * * * ?" />
- <task:scheduled ref="testService" method="sayBye" cron="7/13 * * * * ?" />
- </task:scheduled-tasks>
- </beans>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.0.xsd">
<bean id="testService" class="com.xxx.spring.business.TestService" />
<task:scheduled-tasks>
<task:scheduled ref="testService" method="sayHello" cron="3/11 * * * * ?" />
<task:scheduled ref="testService" method="sayBye" cron="7/13 * * * * ?" />
</task:scheduled-tasks>
</beans>
只要用一个新增的<task:scheduled-tasks>就可以了
就是有一点要注意一下,新的时间配置,是类似于cron的语法,比以前强大很多。
不过我只用到了第一个参数:3/11,表示延迟3秒启动,间隔11秒;7/13表示延迟7秒启动,间隔13秒
