spring quartz 初級配置

第一種方法通過xml配置的方式來管理定時任務，配置繁瑣，但是統一管理

    <!-- 任務調度器配置 配置任務線性池 pool-size
    指配的一個scheduled-tasks中所有的運行方法的線程總數
    不同的scheduled-tasks配置了相同的task:scheduler會有相同的總數限制，而不是和的限制-->
    <task:scheduler id="scheduler" pool-size="2" />
    <!-- 指定運行的方法和運行時間規則時間
    task:scheduler/@pool-size：調度線程池的大小，調度線程在被調度任務完成前不會空閒
    task:scheduled/@cron：cron表達式，注意，若上次任務未完成，即使到了下一次調度時間，任務也不會重複調度 -->
    <task:scheduled-tasks scheduler="scheduler">
        <!-- 一秒一次 -->
        <task:scheduled ref="jobTest" method="jobPrint" cron="*/1 * * * * ?"/>
        <task:scheduled ref="jobTest" method="jobPrint2" cron="*/1 * * * * ?"/>

第二種方法通過自動讀取註解管理定時任務，這種方法不利於管理，因爲配置都在各個類中，無法統一管理

    <!-- job 的包 加載定時任務實現類-->
    <context:component-scan base-package="com.galaxy.fym.job"></context:component-scan>
    <!-- 第二種方法 start -->
    <!-- Spring定時器註解開關-->
    <task:annotation-driven executor="executor" scheduler="scheduler" proxy-target-class="true"></task:annotation-driven>
    <task:scheduler id="scheduler" pool-size="2" />
    <!--
    task:executor/@pool-size：可以指定執行線程池的初始大小、最大大小
    task:executor/@queue-capacity：等待執行的任務隊列的容量
    task:executor/@rejection-policy：當等待隊列爆了時的策略，分爲丟棄、由任務執行器直接運行等方式
    ABORT 終止； CALLER_RUNS 調用運行； DISCARD丟棄；DISCARD_OLDEST 丟棄最老的-->
    <task:executor id="executor" pool-size="100-200" keep-alive="3600" queue-capacity="500" rejection-policy="CALLER_RUNS"/>
    <!-- 第二種方法 end -->
