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"); } }
