1.首先将spring的jar包以及quartz的jar包导入lib下
2.配置web.xml如下：
就是将spring的监听配置进去
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
3.在applicationContext.xml文件中配置quertz，如下：
<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">
<!--1. 业务配置，类-->
<bean id="testJob" class="com.sendmsg.MsgSender"/>
<!--2. JobDetail的配置 -->
<bean id="testJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="testJob"/>
<property name="targetMethod" value="sendMsg"/><!-- 执行方法 -->
<property name="concurrent" value="false"/>
</bean>
<!--3. Trigger的配置 -->
<bean id="testTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="testJobDetail"/>
<property name="cronExpression" value="0 0 9 * * ?"/><!--0 0 9 * * ? 每天早上9点触发一次 /59 * * * * ?59秒触发-->
</bean>
<!--4. 启动定时器 -->
<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="testTrigger"/>
</list>
</property>
<property name="autoStartup" value="true"/>
</bean>
</beans>
4.将项目部署上去，会自动定时执行配置的方法
