disconf-基於xml分佈式配置管理cronjob

本文介紹disconf如何管理cronjob的配置

spring的cronjob有2種實現方式：存入哦你job和scheduler

新建cronjob.properties，內容爲：

# cron job
task.pool.size=20
task.getMoney.delay=1000
task.getCar.cronExpression=*/1 * * * * ?

新建cronjob.xml，內容爲：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
  xmlns:task="http://www.springframework.org/schema/task"
  xsi:schemaLocation="http://www.springframework.org/schema/beans
                            http://www.springframework.org/schema/beans/spring-beans.xsd
                            http://www.springframework.org/schema/task
                        http://www.springframework.org/schema/task/spring-task.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context.xsd">

  <!-- 定時get car -->
  <bean id="getCar" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    <property name="targetObject" ref="cronJobService" />
    <property name="targetMethod" value="getCar" />
  </bean>
  <bean id="getCarJob" class="org.springframework.scheduling.quartz.CronTriggerBean">
    <property name="jobDetail" ref="getCar" />
    <property name="cronExpression" value="${task.getCar.cronExpression}">
    </property>
  </bean>

  <!-- task啓動列表 -->
  <bean id="startQuertz" lazy-init="false" autowire="no"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    <property name="triggers">
      <list>
        <ref bean="getCarJob" />
      </list>
    </property>
  </bean>

  <!--處理任務 -->
  <bean id="scheduler" class="org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler">
    <property name="poolSize" value="${task.pool.size}" />
    <property name="waitForTasksToCompleteOnShutdown" value="true" />
  </bean>
  <task:scheduled-tasks scheduler="scheduler">
    <task:scheduled ref="cronJobService" method="getMoney"
      fixed-delay="${task.getMoney.delay}" />
  </task:scheduled-tasks>
</beans>

這個比較簡單
