spring boot的quartz的配置方式

方式1：添加注解
在定时类上添加注解
@Component
@EnableScheduling
在定时事件上添加注解
@Scheduled(fixedRate = 1000 * 30) 或 @Scheduled(cron="0/5 * * * * *")
完整实例

@Component@Configurable@EnableSchedulingpublic class ScheduledTasks {@Scheduled(fixedRate = 1000 * 30)public void printCurrentTime() {System.out.println("current"+dateFormat().format(new Date()));}@Scheduled(cron="0/5 * * * * *")public void printCurrentByCron() {System.out.println("corn" + dateFormat().format(new Date()));}private SimpleDateFormat dateFormat() {return new SimpleDateFormat("HH:mm:ss");}}

方式2：配置

第一步：添加依赖

   <dependency>        <groupId>org.quartz-scheduler</groupId>        <artifactId>quartz</artifactId>        <version>2.2.3</version>    </dependency>        <dependency><!-- 该依赖必加，里面有sping对schedule的支持 -->      <groupId>org.springframework</groupId>      <artifactId>spring-context-support</artifactId>      </dependency>  


第二步：定义配置文件 quartz.xml，名字随意，暂定：spring-mvc（启动时需要注入，见第6步）
<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:mvc="http://www.springframework.org/schema/mvc"           xmlns:aop="http://www.springframework.org/schema/aop"           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-4.2.xsd           http://www.springframework.org/schema/mvc           http://www.springframework.org/schema/mvc/spring-mvc.xsd           http://www.springframework.org/schema/aop           http://www.springframework.org/schema/aop/spring-aop.xsd           http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task.xsd">            <aop:config proxy-target-class="true"/>        <context:annotation-config/>    <!-- 利用import引入定时器的文件 -->        <import resource="spring-quartz.xml"/>        </beans>


第四部：添加定时器文件spring-quartz.xml
<beans xmlns="http://www.springframework.org/schema/beans"           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"           xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">            <!-- 使用MethodInvokingJobDetailFactoryBean，任务类可以不实现Job接口，通过targetMethod指定调用方法-->        <bean id="taskJob" class="com.example.quartz.test.TestTask"/>        <bean id="jobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">            <property name="group" value="job_work"/>            <property name="name" value="job_work_name"/>            <!--false表示等上一个任务执行完后再开启新的任务-->            <property name="concurrent" value="false"/>            <property name="targetObject">                <ref bean="taskJob"/>            </property>            <property name="targetMethod">                <value>run</value>            </property>        </bean>        <!--  调度触发器 -->        <bean id="myTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">            <property name="name" value="work_default_name"/>            <property name="group" value="work_default"/>            <property name="jobDetail">                <ref bean="jobDetail" />            </property>            <property name="cronExpression">                <value>0/10 * * * * ?</value>            </property>        </bean>        <!-- 调度工厂 -->        <bean id="scheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">            <property name="triggers">                <list>                    <ref bean="myTrigger"/>                </list>            </property>        </bean>    </beans>

第五步：创建定时器需要的类 TestTask
package com.example.quartz.test;        import org.slf4j.Logger;    import org.slf4j.LoggerFactory;        public class TestTask {            /** 日志对象 */        private static final Logger LOG = LoggerFactory.getLogger(TestTask.class);        public void run() {            if (LOG.isInfoEnabled()) {                LOG.info("测试任务线程开始执行");            }            System.out.println("quarty run .....");        }    }

第6步：启动时扫描quartz文件
主要是这个注解 @ImportResource(locations={"classpath:spring-mvc.xml"})，这样springboot就可以扫描到我们的配置文件了
package com.example;        import org.junit.runner.RunWith;    import org.springframework.beans.factory.annotation.Autowired;    import org.springframework.boot.SpringApplication;    import org.springframework.boot.autoconfigure.SpringBootApplication;    import org.springframework.context.annotation.ImportResource;    import org.springframework.jms.core.JmsTemplate;    import org.springframework.scheduling.annotation.EnableScheduling;    import org.springframework.test.context.ContextConfiguration;    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;        @RunWith(SpringJUnit4ClassRunner.class)    @SpringBootApplication    @ImportResource(locations={"classpath:spring-mvc.xml"})    @EnableScheduling    public class DemoApplication{           @Autowired       private JmsTemplate jmsTemplate;           public static void main(String[] args) {          SpringApplication.run(DemoApplication.class, args);       }    }
