spring+quartz

本文只介绍最简单的spring+quartz
首先先贴需要的依赖（pom.xml）

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0modelVersion>

    <groupId>com.superBF37groupId>
    <artifactId>quartzartifactId>
    <version>0.0.1-SNAPSHOTversion>
    <packaging>jarpackaging>

    <name>quartzname>
    <url>http://maven.apache.orgurl>

    <properties>
        <project.build.sourceEncoding>UTF-8project.build.sourceEncoding>

    <dependencies>

            <version>3.3.2version>
        dependency>

接着是需要的java类（简单的任务）

package com.superBF37.quartz;

import java.util.Date;

import org.apache.commons.lang3.time.DateFormatUtils;



public class MyJob {
    public void printWorkTime() {
        System.out.println("我是定时任务.我的执行时间是："+DateFormatUtils.format(new Date(), "yyyy-MM-dd'T'HH:mm:ss"));
    }
}

接着是spring-quartz.xml

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

    <bean name="myJobScheduleTask" class="com.superBF37.quartz.MyJob">bean>

    <bean id="printWorkTimeShelvesInvokingJob"
        class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject" ref="myJobScheduleTask" />
        <property name="targetMethod" value="printWorkTime" />
    bean>

    <bean id="myJobShelvesTrigger"
        class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail" ref="printWorkTimeShelvesInvokingJob" />
        <property name="cronExpression" value="0/5 * * * * ? " />
    bean>

    <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"
        lazy-init="false" destroy-method="destroy">
        <property name="triggers">
            <list>
                <ref bean="myJobShelvesTrigger" />
            list>
        property>
    bean>
beans>  

applicationContext.xml

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

    <import resource="spring-quartz.xml"/>


beans>

项目启动类：

package com.superBF37.quartz;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class App {

    public static void main(String[] args) {
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
        context.start();
    }
}

启动结果：

到这里就结束了？

上面提到的为什么加入spring-tx依赖，我现在还没弄懂，但是如果不加，启动会报错：

大家知不知道为什么呢？是不是我配置的用到了不该用的东西？希望有人可以给出答案
