使用方法：
基于XML方式配置调用：
1 任务类实现：
package com.demo.schedule; public class ScheduleTask { private int i=0; public void process(){ System.out.println("run to " + i++ + " times"); } }
2 spring配置文件 WebRoot\WEB-INF\applicationContext.xml
<?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: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/task http://www.springframework.org/schema/task/spring-task-3.0.xsd"> <!-- 任务bean --> <bean id="scheduleTask" class="com.demo.schedule.ScheduleTask"></bean> <task:scheduler id="scheduler" pool-size="8"/> <task:scheduled-tasks scheduler="scheduler"> <!-- 定时调用，间隔5s执行一次 --> <task:scheduled ref="scheduleTask" method="process" fixed-delay="5000"/> </task:scheduled-tasks> </beans>
3 web.xml文件配置
<?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"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app>
将项目部署到tomcat服务器上即可定时运行，运行结果：
......
run to 112 times
run to 113 times
run to 114 times
基于Annotation方式配置调用：
package com.demo.schedule; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; @Component("scheduleTask") public class ScheduleTask { private int i = 0; @Scheduled(fixedDelay = 5000) public void process() { System.out.println("run to " + i++ + " times"); } }
spring配置文件：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:task="http://www.springframework.org/schema/task" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd"> <context:annotation-config /> <context:component-scan base-package="com.demo.schedule" /> <task:annotation-driven /> <!-- 任务bean <bean id="scheduleTask" class="com.demo.schedule.ScheduleTask"></bean> --> <task:scheduler id="scheduler" pool-size="8"/> <task:scheduled-tasks scheduler="scheduler"> <!-- 定时调用，间隔5s执行一次 --> <task:scheduled ref="scheduleTask" method="process" fixed-delay="5000"/> </task:scheduled-tasks> </beans>
3 web.xml文件配置
