spring3 task namespace

spring framework을 쓴지 어언 몇년인데 아직도
네임스페이스를 못잡아서 헤메냐 - -;;

* namespace 설정

<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/task
        http://www.springframework.org/schema/task/spring-task-3.0.xsd">

* tag 설정 예제

<task:scheduler id="myScheduler"/>
<task:scheduled-tasks scheduler="myScheduler">
   <task:scheduled ref="pushService" method="excute" fixed-delay="5000"/>
</task:scheduled-tasks>
<bean id="pushService" class="com.PushService" autowire="byName"/>
