Question

我必须将数据从资源表移动到事件表以删除资源表。考虑一下，Table模式如下， MySQL的＆GT; desc事件

+-----------------+--------------+------+-----+---------+----------------+
| Field           | Type         | Null | Key | Default | Extra          |
+-----------------+--------------+------+-----+---------+----------------+
| event_id        | bigint(20)   | NO   | PRI | NULL    | auto_increment |
| path            | varchar(255) | YES  |     | NULL    |                |
+-----------------+--------------+------+-----+---------+----------------+

的MySQL＆GT; desc资源;

+--------------------+--------------+------+-----+---------+----------------+
| Field              | Type         | Null | Key | Default | Extra          |
+--------------------+--------------+------+-----+---------+----------------+
| resource_id        | bigint(20)   | NO   | PRI | NULL    | auto_increment |
| jcr_id             | varchar(500) | YES  |     | NULL    |                |
+--------------------+--------------+------+-----+---------+----------------+

事件路径包含jcr_id或resource_id，如果它包含jcr_id，则从资源表中输入，然后使用jcr_id更新事件路径值，然后删除。

在迭代每个resource_id时考虑遵循Psuedo代码，

 result = select event_id from event where path=_resource_id;
 if result is empty 
   delete from resource where resource_id= _resource_id;
 else 
   update event set path=jcr_id where event_id= result;
   delete from resource where resource_id= _resource_id;

试试这个。

    <route> 

    <from ref="minaEndpoint" />
        <threads>
            <bean ref="work-to-do" method="work"/>
        </threads>
    </route>
