使用Spring的环境要求是:JDK1.8以上、Maven3.0以上。

      Maven依赖

                   SpringTask集成在SpringContext中,所以只需要SpringContext即可。

                   可以使用maven-compiler-plugin显式的指定JDK版本。

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>4.3.12.RELEASE</version>
</dependency>
<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.5.1</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

Spring xml配置(基于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: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.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
       http://www.springframework.org/schema/task  http://www.springframework.org/schema/task/spring-task-4.1.xsd">
    <!--配置注解扫描-->
    <context:component-scan base-package="com.cky.schadule"/>
    <task:scheduler id="taskScheduler" pool-size="100" />
    <task:scheduled-tasks scheduler="taskScheduler">
        <!--每30s触发一次-->
        <task:scheduled ref="schaduleDemo" method="sayHello1" cron="0/5 * * * * ?"/>
        <!--每10s触发一次-->
        <task:scheduled ref="schaduleDemo" method="sayHello2" cron="0/10 * * * * ?"/>
    </task:scheduled-tasks>
</beans>    

任务类

@Component
public class SchaduleDemo {
    public void sayHello1(){
        System.out.println("task1:hello~ now time is"+ LocalTime.now());
    }
    public void sayHello2(){
        System.out.println("task2:hello~ now time is0"+ LocalTime.now());
    }

    public static void main(String[] args){
        ApplicationContext context=new ClassPathXmlApplicationContext("classpath:/application-context.xml");
    }
}

      Spring.xml配置(基于注解)

<?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.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
       http://www.springframework.org/schema/task  http://www.springframework.org/schema/task/spring-task-4.1.xsd">
    <!--配置注解扫描-->
    <context:component-scan base-package="com.cky.schadule"/>
    <task:scheduler id="taskScheduler" pool-size="100" />
    <!--开启注解驱动-->
    <task:annotation-driven scheduler="taskScheduler"/>
</beans>

任务类

@Component
public class SchaduleDemo {
    @Scheduled(cron = "0/5 * * * * ?")
    public void sayHello1(){
        System.out.println("task1:hello~ now time is"+ LocalTime.now());
    }
    @Scheduled(cron = "0/10 * * * * ?")
    public void sayHello2(){
        System.out.println("task2:hello~ now time is0"+ LocalTime.now());
    }

    public static void main(String[] args){
        ApplicationContext context=new ClassPathXmlApplicationContext("classpath:/application-context.xml");
    }

}
