quartz定時定時任務執行兩次

quartz框架沒問題。

流程：

sping-quartz配置

    <context:annotation-config/>
     
    <task:annotation-driven/>

     <!-- 業務對象 --> 
     <bean id="testJobTask" class="com.sunyard.quartz.TestQuartzTask" />
     <!-- 自動掃描包 -->
    <context:component-scan base-package="com.sunyard.quartz.*" />
    
    <!-- 定時任務start -->
  
     <!-- 調度業務 -->  
     <bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
         <property name="targetObject" ref="testJobTask" />  
         <property name="targetMethod" value="execute" />    
     </bean>
 
     <!-- 增長調用的觸發器，觸發時間 並注入到調度工廠-->  
     <bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
         <property name="jobDetail" ref="jobDetail" />  
         <property name="cronExpression" value="0/10 * * * * ? *" /> 
     </bean>
 
     <!-- 設置調度工廠 注入觸發器-->
     <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
         <property name="triggers">
             <list>
                 <ref bean="cronTrigger" />
             </list>
         </property>
     </bean>
 
     <!-- 定時任務end -->

</beans> 

以後在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>

測試

/**
 * 定時任務--打印測試定時任務是否成功
 * @author wang
 *
 */
public class TestQuartzTask{
    public void execute() {
        System.out.println("定時任務已啓動！");
    }
}

以後發現啓動以後輸出兩行，即任務啓動兩次。

最終解決：

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

將appBase置空便可
