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

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

<!-- 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>
    </bean>
