Spring结合Quartz实现多任务定时调用

Quartz框架提供了丰富的任务调度支持，比如，在何时执行何种任务，它是一个开源的由OpenSymphony维护的项目，开发者能够在Java EE，或单独的Java SE应用中使用它。无论是简单的任务调度，还是复杂的企业级应用，Quartz都能够很好地胜任。

如果开发者需要开发如下方面的应用，则Quartz是理想的选择。◆驱动工作流：比如，如果新创建的流程任务需要在2小时内处理完，则在2小时后Quartz会检查订单是否成功处理。如果没有处理，则Quartz会依据工作流定义的规则来对订单进行处理，销毁它，或者进行其他处理。◆系统维护工作：比如，在每个工作日的固定时间将RDBMS中的内容导出为XML文件。配置Spring的文件：

</beans>

任务一：TestJob

package com.mzsx.spring.quartz;
import java.util.Date;
public class TestJob {
public void execute(){
try{
System.out.println("TestJob:------------:"+new Date());
}catch(Exception ex){
ex.printStackTrace();
}
}
}

任务二：TestJobTwo

package com.mzsx.spring.quartz;
import java.util.Date;
public class TestJobTwo {
public void execute(){
try{
System.out.println("TestJobTwo:------------:"+new Date());
}catch(Exception ex){
ex.printStackTrace();
}
}
}

测试类：

package com.mzsx.spring.test;
import java.util.Date;
import javax.security.auth.Destroyable;
import org.junit.Test;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.AbstractApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.mzsx.spring.ClasspathDemo;
import com.mzsx.spring.aop.StaticLog;
import com.mzsx.spring.contorller.UserContorller;
import com.mzsx.spring.el.Cat;
import com.mzsx.spring.el.Dog;
import com.mzsx.spring.initafter.InitAfter;
import com.mzsx.spring.initafter.InitMethodAfter;
import com.mzsx.spring.model.Person;
import com.mzsx.spring.service.IUserService;
public class TestQuartz {
@Test
public void testQuartz(){
System.out.println("Test start....."+new Date());
ApplicationContext context = new ClassPathXmlApplicationContext("quartz.xml");
try {
Thread.sleep(30000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("Test end.");
}

}
