SpringMVC scheduled task (task) to open multiple threads of execution

　　spring the task default is single-threaded execution, if too many regular tasks, a task execution time is too long, it may affect the frequency of execution of other tasks, therefore, it is necessary to add multi-threaded parallel execution, can effectively reduce the task is chance of impact. The solution is to modify the configuration xml file, as follows:

<?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/context
          http://www.springframework.org/schema/context/spring-context.xsd
          http://www.springframework.org/schema/task
          http://www.springframework.org/schema/task/spring-task.xsd"
          default-autowire="byName" default-lazy-init="false">

    <!-- 1.扫描指定的包 -->
    <context:component-scan base-package="com.qfx.system.task"/>

    <!-- 2.启用定时任务 -->
    <!-- <task:annotation-driven /> -->
    <task:annotation-driven scheduler="myTask" />

    <!-- 3.配置定时任务的线程池 -->
    <task:scheduler id="myTask" pool-size="5"/>
</beans>
