quartz框架没问题。

流程：

sping-quartz配置

    <context:annotation-config/>

    <task:annotation-driven/>

     <!-- 业务对象 -->

     <bean id="testJobTask" class="com.sunyard.quartz.TestQuartzTask" />

     <!-- 自动扫描包 -->

    <context:component-scan base-package="com.sunyard.quartz.*" />

    <!-- 定时任务start -->

     <!-- 调度业务 -->

     <bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">

         <property name="targetObject" ref="testJobTask" />

         <property name="targetMethod" value="execute" />

     </bean>

     <!-- 增加调用的触发器，触发时间 并注入到调度工厂-->

     <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">

         <property name="jobDetail" ref="jobDetail" />

         <property name="cronExpression" value="0/10 * * * * ? *" />

     </bean>

     <!-- 设置调度工厂 注入触发器-->

     <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">

         <property name="triggers">

             <list>

                 <ref bean="cronTrigger" />

             </list>

         </property>

     </bean>

     <!-- 定时任务end -->

</beans> 

之后在web.xml中

 <listener>

    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

  </listener>

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>

       classpath:spring-mybatis.xml,

       classpath:spring-quartz.xml

    </param-value>

  </context-param>

测试

/**

 * 定时任务--打印测试定时任务是否成功

 * @author wang

 *

 */

public class TestQuartzTask{

    public void execute() {

        System.out.println("定时任务已启动！");

    }

}

之后发现启动之后输出两行，即任务启动两次。

最终解决：

<Host appBase="" autoDeploy="true" name="localhost" unpackWARs="true">

将appBase置空即可
