这里只是做简单的记录如何实现。
一、基于配置文件的实现
①编写需要调度的类
package com.study;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
//@Component
public class QuartzJob {
public QuartzJob(){
System.out.println("Quartzjob创建成功");
}
//@Scheduled(cron = "0/1 * * * * ? ")
public void run(){
System.out.println("Quartz执行的任务调度");
}
}注：里面的注解是后面的是注解的实现中用到的
②设置配置文件spring-quartz.xml
<!--?xml version="1.0" encoding="UTF-8"?--> <beans> <bean id="quartzJob" class="com.study.QuartzJob"></bean> <!-- 定义调用对象和调用对象的方法 --> <bean id="jobtask" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean"> <!-- 调用的类 --> <property name="targetObject"> <ref bean="quartzJob"> </ref></property> <!-- 调用类中的方法 --> <property name="targetMethod"> <value>run</value> </property> </bean> <!-- 定义触发时间 --> <bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail"> <ref bean="jobtask"> </ref></property> <!-- cron表达式 --> <property name="cronExpression"> <!--<value>10,15,20,25,30,35,40,45,50,55 * * * * ?</value>--> <value>0/1 * * * * ?</value> </property> </bean> <!-- 总管理类 如果将lazy-init='false'那么容器启动就会执行调度程序 --> <bean id="startQuertz" lazy-init="false" autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <property name="triggers"> <list> <ref bean="doTime"> </ref></list> </property> </bean> </beans>
注意cron表达式，这里配置的是每隔1s执行。
③启动spring容器
package com.study;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
public static void main(String[] args) {
System.out.println("启动spring容器");
ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring-quartz.xml");
}
}二、基于注解的实现
①配置需要调度的类，并添加注解
package com.study;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
@Component
public class QuartzJob {
public QuartzJob(){
System.out.println("Quartzjob创建成功");
}
@Scheduled(cron = "0/1 * * * * ? ")
public void run(){
System.out.println("Quartz执行的任务调度");
}
}②添加配置文件
<!--?xml version="1.0" encoding="UTF-8"?--> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:task="http://www.springframework.org/schema/task" xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd "> <task:annotation-driven> <context:component-scan base-package="com.study"> <context:annotation-config> </context:annotation-config></context:component-scan></task:annotation-driven></beans>
③启动容器，这里通过配置web.xml启动
<!--?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"> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-quartz2.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
