添加maven依赖。pom.xml 中添加jar文件  <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz</artifactId> <version>2.2.1</version> </dependency> <dependency> <groupId>org.quartz-scheduler</groupId> <artifactId>quartz-jobs</artifactId> <version>2.2.1</version> </dependency>

2.任务交给spring管理。web.xml 文件中引入任务调度的配置文件

  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath*:/config/applicationContext-shiro.xml,
        classpath*:/config/applicationContext-quartz.xml
    </param-value>
    </context-param>

配置任务调度。编写 applicationContext-quartz.xml 配置文件

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

    <!-- 定时器工作调度的bean -->
    <bean id="myJob" class="com.xx.xxxx.ws.quarter.MyJob" />
    <!-- job的配置开始 -->
    <bean id="myJobDetail"
    class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject">
        <ref bean="myJob" />
    </property>
    <property name="targetMethod">
        <value>work</value>
    </property>
    </bean>
    <!-- 调度的配置开始 -->
    <bean id="crontestJobTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
    <property name="jobDetail">
        <ref bean="myJobDetail" />
    </property>
    <property name="cronExpression">
        <value>0/10 * * * * ?</value>
    </property>
    </bean>
    <!-- 启动触发器的配置开始 -->
    <bean name="startQuertz" lazy-init="false" autowire="no"
    class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
        <ref bean="crontestJobTrigger" />
        </list>
    </property>
    </bean>
</beans>

编写任务类。编写定时器类 <bean id="myJob" class="com.xx.xxxx.ws.quarter.MyJob" /> public class MyJob { public void work() { System.out.println("work done----------"); } }
如何配置quartz(随spring启动)执行一次  <bean id="rsh_simpleTrigger1" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean"> <property name="jobDetail" ref="myJobDetail" /> <property name="startDelay" value="500" /> <property name="repeatInterval" value="0" /> <property name="repeatCount" value="0" /> </bean>

触发器当中添加配置任务

<!-- 启动触发器的配置开始 -->
    <bean name="startQuertz" lazy-init="false" autowire="no"
    class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
        <list>
        <ref bean="rsh_simpleTrigger1" />
        <ref bean="crontestJobTrigger" />
        </list>
    </property>
    </bean>
