配置quartz启动时就执行一次
- 添加maven依赖。pom.xml 中添加jar文件 <!-- 作业任务调度机制 --> <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

<!-- 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">

</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 <!-- 配置项目启动后任务就执行一次 --> <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>
