程序逻辑:web.xml添加

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/config/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

applicationContext.xml文件内容如下:

<?xml version="1.0" encoding="UTF-8"?>
<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-2.0.xsd">

<bean id="remindQuartz" class="test.quartz.RemindQuartz"/>

<bean id="remindQuartzTask" class= "org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="remindQuartz" />
<property name="targetMethod" value="perform" />
<property name="concurrent" value="false" />
</bean>
<!-- 调度器 -->
