spring quartz 定时任务，访问bean空指针异常

Question

做了一个定时任务，但是在运行的时候总是报错：XmlToTableTask 中的IHrmisBiz_为空public class XmlToTableTask {  private IHrmisBiz IHrmisBiz_;  private static boolean isRunning = false;  public void run() {   if (!isRunning) {
isRunning = true;
try {
 List list = this.IHrmisBiz_.parseXml();---空指针异常
 this.IHrmisBiz_.wirteDB(list);
} catch (Exception e) {
} isRunning = false;
  } else {
Log.debug("上一次任务执行还未结束..."); // 上一次任务执行还未结束
  }
 }  /**

Answer 1

<property name="IHrmisBiz_"> 
<ref bean="HrmisBiz" /> 
</property> 
 ref是子元素??好象ref是property的属性来的吧??
试
<property name="IHrmisBiz_" ref="HrmisBiz"/> 

Answer 2

应该是一样的，即便改成<property name="IHrmisBiz_" ref="HrmisBiz"/> 一样是空指针异常。继续等待

Answer 3

<bean name="ImportBDJob" class="org.springframework.scheduling.quartz.JobDetailBean">
   <property name="jobClass" value="com.pracbiz.zuellig.rdc.job.ImportBDJob" />
