spring定时器quartz

为了记录一个完整的定时任务的例子，从零配置到代码。

1.首先，web.xml

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
  <display-name>kongfu testdisplay-name>
  
  <filter>
        <filter-name>spring character encoding filterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>
            <param-name>forceEncodingparam-name>
            <param-value>trueparam-value>
        init-param>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>UTF-8param-value>
        init-param>
    filter>
    <filter-mapping>
        <filter-name>spring character encoding filterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath*:/spring/application-context.xmlparam-value>
    context-param>

    <servlet>
        <servlet-name>spring webservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        <init-param>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath*:/spring/web-context.xmlparam-value>
        init-param>
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>spring webservlet-name>
        <url-pattern>/url-pattern>
    servlet-mapping>
web-app>

2.加入jar包：pom.xml

        
        <dependency>
            <groupId>org.springframeworkgroupId>
            <artifactId>spring-coreartifactId>
            <version>${org.springframework.version}version>
        dependency>
        <dependency>
            <groupId>org.springframeworkgroupId>
            <artifactId>spring-webmvcartifactId>
            <version>${org.springframework.version}version>
        dependency>
        <dependency>
            <groupId>org.springframeworkgroupId>
            <artifactId>spring-txartifactId>
            <version>${org.springframework.version}version>
        dependency>
        
        <dependency>
            <groupId>org.quartz-schedulergroupId>
            <artifactId>quartzartifactId>
            <version>2.2.1version>
        dependency>

3.spring的配置:

（1）web-context.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"
        default-lazy-init="true">
    <mvc:annotation-driven/>
    <context:component-scan base-package="com.kongfu.business"/>
    
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations" value="classpath:properties/*.properties" />
        <property name="fileEncoding" value="UTF-8" />
    bean>
beans>    

（2）application-context.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <context:component-scan base-package="com.kongfu.business"/>
    
    <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations" value="classpath:properties/*.properties" />
        <property name="fileEncoding" value="UTF-8" />
    bean>

    <bean id="messageSource"
        class="org.springframework.context.support.ResourceBundleMessageSource">
        <property name="basenames">
            <list>
                <value>i18n/errorvalue>
                <value>i18n/messagevalue>
            list>
        property>
    bean>

    <import resource="classpath:spring/application-*-context.xml" />

beans>

（3）application-quartz-context.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd" default-lazy-init="false">
    
    <bean id="abstractJobDetail" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" abstract="true">
        <property name="concurrent" value="false" />
        <property name="targetMethod" value="handle" />
    bean>

    
    <bean id="abstractCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean" abstract="true" />
    <bean id="returnInvestTrigger" parent="abstractCronTrigger">
        <property name="jobDetail">
            <bean parent="abstractJobDetail">
                <property name="targetObject" ref="overdueScheduleHandler" />
            bean>
        property>
        <property name="cronExpression" value="0 0/2 * * * ?" />
    bean>

    
    <bean id="scheduler"  class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="returnInvestTrigger"/>
            list>
        property>
    bean> 
beans>

4.定时任务执行类

AbstractScheduleHandler

public abstract class AbstractScheduleHandler {
    protected final Logger logger = LoggerFactory.getLogger(AbstractScheduleHandler.class);

    public void handle() throws IllegalAccessException, Exception {
        if (logger.isDebugEnabled()) {
            logger.debug("start schedule[" + getClass() + "].");
        }
        doHandle();
        if (logger.isDebugEnabled()) {
            logger.debug("end schedule[" + getClass() + "].");
        }
    }

    protected abstract void doHandle() throws IllegalAccessException, Exception;
}

OverdueScheduleHandler

/**
 * 定时任务
 * 
 * @author CNkongfu
 * @date 2017年2月13日
 */
@Component
public class OverdueScheduleHandler extends AbstractScheduleHandler {

    @Override
    protected void doHandle() throws IllegalAccessException, Exception {
        quartz1();
    }

    private void quartz1() {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:SS");
        System.out.println("this is a quartz " + sdf.format(new Date()));
    }

}

执行结果
