quartz定时定时任务执行两次

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
