  • Spring任务调度之SpringTask基于XML和基于注解的使用示例

    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");
        }
    
    }
