准备

创建 Maven web 工程，引入以下依赖：

<!-- pom.xml -->
<?xml version="1.0" encoding="UTF-8"?>
<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>4.0.0</modelVersion>

    <groupId>com.zze.quartz</groupId>
    <artifactId>quartz_spring</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>war</packaging>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.quartz-scheduler</groupId>
            <artifactId>quartz</artifactId>
            <version>2.2.3</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.2</version>
                <configuration>
                    <port>8080</port>
                    <path>/</path>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

加载 Spring 核心配置文件：

<!-- WEB-INF/web.xml -->
<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
</web-app>

使用

XML 方式

1、创建任务类：

// com.zze.quartz.HelloJob
import java.text.SimpleDateFormat;
import java.util.Date;

public class HelloJob {
    public void run() {
        System.out.println("Hello quartz! now ->" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
    }
}

2、Spring 配置：

<!-- applicationContext.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"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
                            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">

    <!-- 定时任务的bean -->
    <bean id="helloJob" class="com.zze.quartz.HelloJob"/>

    <bean id="testQuartzJob_jd"
          class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <property name="targetObject">
            <ref bean="helloJob"/>
        </property>
        <property name="targetMethod" value="run"></property>
    </bean>

    <!-- 调度的配置&job的配置 -->
    <bean id="testQuartzJob_ct" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
        <property name="jobDetail">
            <ref bean="testQuartzJob_jd"/>
        </property>
        <!--每五秒执行-->
        <property name="cronExpression" value="*/5 * * * * ?"></property>
    </bean>

    <!-- 开启定时任务-->
    <bean id="startQuertz" class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
        <property name="triggers">
            <list>
                <ref bean="testQuartzJob_ct"/>
            </list>
        </property>
    </bean>
</beans>

3、启动项目，观察控制台：

注解方式

1、创建任务类并使用注解：

// com.zze.quartz.HelloJob
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.text.SimpleDateFormat;
import java.util.Date;
@Component
public class HelloJob {
    @Scheduled(cron = "*/1 * * * * ?") // 每秒执行
    public void run() {
        System.out.println("Hello quartz! now ->" + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
    }
}

2、配置 Spring 包扫描：

<!-- applicationContext.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: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-3.0.xsd">

    <!-- task任务扫描注解 -->
    <task:annotation-driven/>
    <!-- 扫描位置 -->
    <context:component-scan base-package="com.zze.quartz"/>
</beans>
