本文对比了Spring框架中两种不同的任务调度实现方式，通过XML配置和代码实现展示了各自的特点和性能差异，最终推荐了一种更高效的实现方法。

第二种实现方式

package com.shengyidi.app.task;


public class QuartzTestS {

	public void start() {

		testMethod();

	}

	private void testMethod() {

		System.out.println("\n\n_______________" + Thread.currentThread().getName() + "_start________________________");
		for (int i = 0; i < 5; i++) {
			System.out.println(Thread.currentThread().getName() + " " + i);
			try {
				Thread.currentThread().sleep(30000);
			} catch (InterruptedException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}
		System.out.println("\n\n_______________" + Thread.currentThread().getName() + "_end________________________");
	}

}

xml配置

<bean id="quartzTestS" class="com.shengyidi.app.task.QuartzTestS">
	</bean>
	<bean id="quartzTestSTimer"
		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
		<property name="targetObject">
			<ref bean="quartzTestS" />
		</property>
		<property name="targetMethod">
			<value>start</value>
		</property>
		<property name="concurrent" value="false" />
	</bean>
	<bean id="test2"
		class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail">
			<ref bean="quartzTestSTimer" />
		</property>
		<property name="cronExpression">
			<value>0 /1 * * * ?</value>
		</property>
	</bean>

	<bean
		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<list>
				<ref bean="test2" />
			</list>
		</property>
	</bean>

总结：

第二种是spring 提供的，第一种是我想的

第一种比第二种快很多。建议使用第一种
