Spring和Quartz整合入门

1.导入maven依赖包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>cn.itcast.maven</groupId>
<artifactId>quartz_spring</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<name>quartz_spring</name>

<dependencies>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.1</version>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz-jobs</artifactId>
<version>2.2.1</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.12</version>
</dependency>
<dependency>

<artifactId>spring-context-support</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>4.1.7.RELEASE</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>

<artifactId>tomcat-maven-plugin</artifactId>
<version>1.1</version>
<configuration>
<port>9888</port>
</configuration>
</plugin>
</plugins>
</build>
</project>

2.配置web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    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">
    
    <!-- spring配置文件位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- spring核心监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

3.编写job程序  job--service

package cn.itcast.quartz.job;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;

import cn.itcast.quartz.service.HelloService;

public class HelloJob implements Job{
    @Autowired
    private HelloService helloService;
    public void execute(JobExecutionContext context) throws JobExecutionException {
        
        helloService.sayHello();
        
    }
    
}

package cn.itcast.quartz.service;

import org.springframework.stereotype.Service;

@Service
public class HelloService {

    public void sayHello() {
        System.out.println("hello,quartz spring");
    }
    
}    

由于在job中Spring管理的bean无法注入,需要在Scheduler中自定义jobFactory

package cn.itcast.quartz.service;

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
import org.springframework.stereotype.Service;

@Service("jobFactory")
public class JobFactory extends AdaptableJobFactory {

    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;

    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle)
            throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }

}

4.配置application.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"
    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.xsd ">
<!-- 扫描包 -->
    <context:component-scan base-package="cn.itcast.quartz" />

    <bean id="helloJob" class="org.springframework.scheduling.quartz.JobDetailFactoryBean">  
        <property name="jobClass" value="cn.itcast.quartz.job.HelloJob"/>  
        <property name="jobDataAsMap">  
             <map>  
                <entry key="timeout" value="5"/>
             </map>  
        </property>  
    </bean> 

    <!-- ======================== 调度触发器 ======================== -->
    <bean id="cronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="helloJob"></property>
        <property name="cronExpression" value="0 54 * * * ?"></property>
    </bean>

    <!-- ======================== 调度工厂 ======================== -->
    <!-- 在job中Spring管理的bean无法注入,需要在scheduler中自定义jobFactory -->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="jobFactory" ref="jobFactory" />
        <property name="triggers">
            <list>
                <ref bean="cronTriggerBean" />
            </list>
        </property>
    </bean>

</beans>
