今天在SPRING上配置一个QUARTZ来做定时任务，
配置好了，启动程序，老是报如下错误：

难道我的DAO里面的程序有问题，表名写错了？
原来是因为applicationContext-quartz.xml配置文件里面的
<beans default-autowire="byName">

<bean id="SmsSendTaskFactory"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="messageTaskScheduledTask" />
</list>
</property>
<property name="configLocation"
value="classpath:quartz.properties" />
</bean>

看看SchedulerFactoryBean里面的源代码，它会用datasource连接数据库，去取数据库里面的任务，然后又找不到表名。所以报错。
看来这个autowire byName不能乱用啊。
把这个default-autowire="byName"去掉，老实的配置SPRING的BEAN就正确了。
