spring实现定时任务之Quartz 1
1.使用MethodInvokingJobDetailFactoryBean
MethodInvokingJobDetailFactoryBean 所指定的任务是普通的 java类.
SimpleJob2.java
public class SimpleJob2
{
public void execute()
{
System.out.println("SimpleJob2");
}
}
{
public void execute()
{
System.out.println("SimpleJob2");
}
}
SimpleJob2.xml:
注意：targetMethod 会去找指定job类中没有参数的指定方法.如：execute(){}
<?xml version="1.0" encoding="UTF-8"?>

<!-- 10 seconds -->

<ref local="simpleTrigger" />
</list>

</bean>
</beans>

运行：主函数加载 spring 配置文件即可：
public static void main(String[] args)
{
ApplicationContext cxt=new FileSystemXmlApplicationContext("config/SimpleJob2.xml");
}
在web中应用 只要在web.xml中加载配置文件即可。
