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"

</beans>
任务类
@Component
