红帽全球峰会235.7.5. 调度的轮询示例
此组件支持调度的轮询，因此可用作轮询消费者。例如，要每分钟轮询数据库：
from("mybatis:selectAllAccounts?delay=60000")
.to("activemq:queue:allAccounts");
from("mybatis:selectAllAccounts?delay=60000")
.to("activemq:queue:allAccounts");如需了解更多选项，请参阅 Polling Consumer 上的"ScheduledPollConsumer Options"。
另外，您可以使用另一种机制来触发调度的轮询，如 Timer 或 Quartz 组件。 在以下示例中，我们轮询数据库，每 30 秒使用 Timer 组件并将数据发送到 JMS 队列：
from("timer://pollTheDatabase?delay=30000")
.to("mybatis:selectAllAccounts")
.to("activemq:queue:allAccounts");
from("timer://pollTheDatabase?delay=30000")
.to("mybatis:selectAllAccounts")
.to("activemq:queue:allAccounts");以及使用的 MyBatis SQL 映射文件：
<!-- Select with no parameters using the result map for Account class. -->
<select id="selectAllAccounts" resultMap="AccountResult">
select * from ACCOUNT
</select>
<!-- Select with no parameters using the result map for Account class. -->
<select id="selectAllAccounts" resultMap="AccountResult">
select * from ACCOUNT
</select>
