配置spring时出现的异常，请帮助解决。

Question

application-context.xml代码如下：

<?xml version="1.0" encoding="UTF-8"?>

<!-- 指定Spring配置文件的Schema信息 -->

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

&lt;!--声明一个定时任务,该类extends java.util.TimerTask --&gt;
&lt;bean id="clock" class="com.mirrors.user.util.MyTesk"&gt;
&lt;/bean&gt;

&lt;!--调度定时任务,把声明的定时任务注入进来,并设置定时参数 --&gt;
&lt;bean id="scheduledClock" class="org.springframework.scheduling.timer.ScheduledTimerTask"&gt;
    &lt;property name="timerTask"&gt;
        &lt;ref bean="clock"/&gt;
    &lt;/property&gt;
    &lt;property name="period"&gt;
        &lt;value&gt;5000&lt;/value&gt;
    &lt;/property&gt;
    &lt;property name="delay"&gt;
        &lt;value&gt;5000&lt;/value&gt;
    &lt;/property&gt;
&lt;/bean&gt;

&lt;!-- 启动定时任务,如果有多个定时任务,则重复步骤一,二,然后把第二步设置的beany放在下面的list列表中.此方法不能精确几点运行定时任务 --&gt;
&lt;bean class="org.springframework.scheduling.timer.TimerFactoryBean"&gt;
    &lt;property name="scheduledTimerTasks"&gt;
        &lt;list&gt;
            &lt;ref bean="scheduledClock"&gt;&lt;/ref&gt;
        &lt;/list&gt;
    &lt;/property&gt;
&lt;/bean&gt;

&lt;!-- 以上一种定时任务不能精确到几点运行，以下一种定时任务能够精确定几点运行 --&gt;

&lt;bean id="quartzClock" class="com.mirrors.user.util.QuartzClock"&gt;&lt;/bean&gt;

&lt;!--这种配置与第一种方法效果一样 
&lt;bean id="quartzClockTask" class="org.springframework.scheduling.quartz.SimpleTriggerBean"&gt;
    &lt;property name="jobDetail"&gt;
        &lt;ref bean="quartzClock"/&gt;
    &lt;/property&gt;
    &lt;property name="startDelay"&gt;
        &lt;value&gt;6000&lt;/value&gt;
    &lt;/property&gt;
    &lt;property name="repeatInterval"&gt;
        &lt;value&gt;6000&lt;/value&gt;
    &lt;/property&gt;
&lt;/bean&gt;
--&gt;

&lt;bean id="cronQuartzClock" class="org.springframework.scheduling.quartz.CronTriggerBean"&gt;
    &lt;property name="jobDetail"&gt;
        &lt;ref bean="quartzClock"&gt;&lt;/ref&gt;
    &lt;/property&gt;
    &lt;property name="cronExpression"&gt;
        &lt;value&gt; 0 0 12,14,16 * * ?&lt;/value&gt;
    &lt;/property&gt;
&lt;/bean&gt;

&lt;bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"&gt;
    &lt;property name="triggers"&gt;
        &lt;list&gt;
            &lt;ref bean="cronQuartzClock"&gt;&lt;/ref&gt;
        &lt;/list&gt;
    &lt;/property&gt;
&lt;/bean&gt;

Answer 1

web.xml 里有重复定义的org.springframework.web.context.ContextLoaderListener
