Spring配置Quartz任务调度、及 ThreadPool 线程池

ONE、除了引入 Spring 相关的 jar 包，还要引入 Quartz 的 jar 包

        <dependency>
            <groupId>org.springframeworkgroupId>
            <artifactId>spring-context-supportartifactId>
            <version>${springversion}version>
        dependency>
        <dependency>
            <groupId>org.quartz-schedulergroupId>
            <artifactId>quartzartifactId>
            <version>2.2.2version>
        dependency>
        <dependency>
            <groupId>org.quartz-schedulergroupId>
            <artifactId>quartz-jobsartifactId>
            <version>2.2.2version>
        dependency>

　　这里用的是 MAVEN，普通工程自行下载 jar 包即可。

TWO、调度任务类 QuartzJob.java

package test;

public class QuartzJob {

    public void work1() {
        System.out.println("Quartz定时器！！！work1 doing…");
    }

    public void work2() {
        System.out.println("Quartz定时器！！！work2 doing…");
    }

}

　　里面定义两个方法，quartz配置文件里也会用两种方式配置 类 和 方法。

THREE、Spring 配置 spring-quartz.xml

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
            http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"
    default-autowire="byName" default-lazy-init="true">
    
    
    <bean id="testJob" class="test.QuartzJob">bean>

    
    <bean id="executor"
        class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
        
        <property name="corePoolSize" value="100" />  
        
        <property name="keepAliveSeconds" value="200" />  
        
        <property name="maxPoolSize" value="100" />  
        
        <property name="queueCapacity" value="2000" /> 
        
        <property name="rejectedExecutionHandler">
            <bean class="java.util.concurrent.ThreadPoolExecutor$CallerRunsPolicy" />
        property> 
    bean>
    

    
    <bean id="testTask"
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        
        <property name="targetObject">
            <ref bean="testJob" />
        property>
        
        <property name="targetMethod">
            <value>work1value>
        property>
    bean>
    <bean id="testTask2"
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        
        <property name="targetObject" ref="testJob" />
        
        <property name="targetMethod" value="work2" />
    bean>

    
    <bean id="jibDoTime"
        class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail">
            <ref bean="testTask" />
        property>
        
        <property name="cronExpression">
            <value>0/1 * * * * ?value>
        property>
    bean>
    <bean id="jibDoTime2"
        class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="testTask2" />
        <property name="cronExpression" value="0/2 * * * * ?" />
    bean>

    
    <bean id="startQuertz" lazy-init="false" autowire="no"
        class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="jibDoTime" />
                <ref bean="jibDoTime2" />
            list>
        property>
        
        <property name="startupDelay" value="5" />
        <property name="taskExecutor" ref="executor" />
    bean>
beans>

FOUR、web.xml 里加载 quartz

       <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>
            classpath:spring-quartz.xml
        param-value>
    context-param>

下面虽然不太重要，但很能说服人~
