    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"

    <!-- spring配置文件位置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>

        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
    </welcome-file-list>
</web-app>

4.创建applicationContext.xml文件

<?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/context http://www.springframework.org/schema/context/spring-context.xsd ">
     
    <context:component-scan base-package="com.baidu" />
     
    <!-- job -->
    <bean id="helloJob"
        class="org.springframework.scheduling.quartz.JobDetailFactoryBean">　　　　　　　　　　<!--不能使用ref-->
         <property name="jobClass" value="com.baidu.quartz.HelloJob" /> 
    </bean>
     
    <!-- trigger -->
    <bean id="simpleTrigger"
        class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
        <property name="jobDetail" ref="helloJob" />
        <!-- 3秒后第一次执行 -->
        <property name="startDelay" value="3000" />
        <!-- 5秒后重复执行 -->
        <property name="repeatInterval" value="5000" />
    </bean>
     
    <!-- scheduler  -->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="simpleTrigger"/>
            </list>
        </property>
    </bean>
     
</beans>

5.编写代码

创建一个service

@Component
public class HelloService {
    public void sayHello(){
        System.out.println("say hello");
    }
}　

方法一：

创建helloJob

11
@Component
public class HelloJob implements Job {
    @Autowired
    private HelloService helloService;
    public void execute(JobExecutionContext context)
            throws JobExecutionException {
        SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
        helloService.sayHello();
        System.out.println("test01");
    }
}

　　方法二：

创建一个JobFactory类

11
12
@Component
public class JobFactory extends AdaptableJobFactory{
    @Autowired
    private AutowireCapableBeanFactory autowireCapableBeanFactory;
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle)
            throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        autowireCapableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

　　修改applicationContext.xml文件

<!-- scheduler  -->
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    　　　　<property name="jobFactory" ref="jobFactory"></property>
        <property name="triggers">
            <list>
                <ref bean="simpleTrigger"/>
            </list>
        </property>
    </bean>

　产生空指针异常

产生的原因：

quartz交给spring管理时，底层对于jobclass的管理并没有交给spring，这样在使用spring管理时会产生连个对象，
