quartz整合spring出现的问题

org.springframework.scheduling.support.TaskUtils$LoggingErrorHandler.handleError Unexpected error occurred in scheduled task.
今天使用quartz的时候报了这个错误，废话不多说直接上代码，最后改成如下配置就可以了

一.首先pom里面导入

      <dependency>
          <groupId>org.quartz-scheduler</groupId>
          <artifactId>quartz</artifactId>
          <version>2.2.3</version>
      </dependency>

二.xml配置;

<bean id="complexJobDetail"
          class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <property name="jobClass" value="com.xx.quartz.DelLogTask" />
        <property name="durability" value="true" />
        <property name="jobDataAsMap"><!-- 非常重要，用来向JobDetail传参 -->
            <map>
                <entry key ="logDao" value-ref="logDao"/>
                <entry key="timeout" value="5" />
            </map>
        </property>
    </bean>
    <bean id="cronTrigger"
          class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="complexJobDetail" />
        <!--0 0 1 * * ? 每天凌晨一点执行-->
        <property name="cronExpression" value="0 2 12 * * ?" />
    </bean>
    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="jobDetails">
            <list>
                <ref bean="complexJobDetail" />
            </list>
        </property>
        <property name="triggers">
            <list>
                <ref bean="cronTrigger" />
            </list>
        </property>
    </bean>
    <!-- 工作的bean -->
    <bean id="delLogTask" class="com.tuxun.quartz.DelLogTask" />

三.job类：

public class DelLogTask extends QuartzJobBean {

    @Autowired
    LogDao logDao;

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        LogDao logDao = (LogDao)context.getJobDetail().getJobDataMap().get("logDao");
        int result = logDao.deleteByTime();
    }
}
