Spring中Quartz任务调度器不能识别注解的问题

Spring中Quartz任务调度器不能识别注解的问题5

原来在项目中使用配置在applicationContext.xml的方式实现了调度器的功能，现在spring升级到3.0.2的版本后想用注解的方式实现发现老出现问题，主要是主动到调度器类中的业务对象不能被识别了。代码如下:

import javax.annotation.Resource;
import javax.annotation.*;

import org.apache.log4j.Logger;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.stereotype.Component;

import com.aisino.heb.cjrqy.cjzdgl.service.CaijizhongduanguanliServiceImple;

@Component
@SuppressWarnings("unchecked")
public class CjzdScann extends QuartzJobBean
{

    @Resource
    private CaijizhongduanguanliServiceImple caijizhongduanguanliServiceImple;//业务对象

    // String filename = pro.getProperty("log4j.appender.E.file");
    private static Logger                    log = Logger
                                                         .getLogger(CjzdScann.class);

    @Override
    protected void executeInternal(JobExecutionContext arg0)
            throws JobExecutionException {
        System.out.println(caijizhongduanguanliServiceImple);
        caijizhongduanguanliServiceImple.cjzdscann();   //调用具体的业务。
    }
}
applicationContext.xml中的配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

<bean id="schedulerFactoryBean"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean" >
<property name="triggers">
<list>
<ref bean="repaymentRulesQuartz" />
</list>
</property>
   </bean>


<bean id="repaymentRulesQuartz" class="org.springframework.scheduling.quartz.SimpleTriggerBean">

<property name="jobDetail">
<ref bean="repaymentRulesTimer"/>
</property>

<property name="startDelay">
<value>6000</value>
</property>

<property name="repeatInterval">
<value>60000</value>
</property>
</bean>



<bean id="repaymentRulesTimer"
class="org.springframework.scheduling.quartz.JobDetailBean">

<property name="jobClass"
value="com.aisino.heb.cjrqy.jobs.CjzdScann">
</property>

</bean>
</beans>

现在项目启动后调度器这个类可以正常被调用，但业务对象却始终为null，也就是没有被注入进来，我从网上查了一下说可以加入lazy-init="true"解决问题，测试后还是不行，报出的错误如下：
2013-05-01 20:33:03.868 Job DEFAULT.repaymentRulesTimer threw an unhandled Exception:

<property name="jobClass"
value="com.aisino.heb.cjrqy.jobs.CjzdScann">
</property>

此处不是由spring创建而是quartz自己反射new 所以不会注入

1、写一个SpringUtils 去获取依赖
可以到 SpringMVC + spring3.1.1 + hibernate4.1.0 集成及常见问题总结下载

2、使用如下代替

    <bean id="cancelOrder" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
          <property name="targetObject" ref="portalOrderCancelEbo" />
          <property name="targetMethod" value="autoCancelOrder" />
          <property name="concurrent" value="false" />
     </bean>
