spring整合quartz定时任务（附demo）（二）

源码下载地址：https://gitee.com/seek412/quartz02.git

在上一章节：Quartz定时任务（附demo）（一）中我们介绍了如何利用quartz创建一个普通的定时任务，本文将介绍spring与quartz的整合，让服务器启动时就运行定时任务

项目结构如下图：

步骤1：引入依赖包

<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://maven.apache.org/POM/4.0.0"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion>
<groupId>com.demo</groupId>
<artifactId>quartz02</artifactId>
<packaging>war</packaging>
<version>1.0-SNAPSHOT</version>
<name>quartz02 Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>3.8.1</version>
<scope>test</scope>
</dependency>

<!-- spring -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>

<!-- spring jdbc-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>

<!-- spring面向切面编程 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-aspects</artifactId>
<version>4.3.7.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>3.2.4.RELEASE</version>
</dependency>
<!-- quartz-->
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>1.8.5</version>
</dependency>

</dependencies>
<build>
<finalName>quartz02</finalName>
<!-- 指定编译版本1.7 -->
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
</configuration>
</plugin>
</plugins>
<!-- 使用的idea,由于idea编译的时候不会把src/main/java中的xml文件编译的class中，需要添加下面语句，eclipse则不用 -->
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
</build>
</project>

注意事项：

spring3.1以下的版本必须使用quartz 2以下的版本，spring 3.1以上的版本必须使用quartz 2以上的版本，否则会报错

如果项目中同时使用了shiro框架，在引入shiro依赖包的时候需要排除quartz包，否则会报错，如下：

<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-quartz</artifactId>
<version>1.2.5</version>
<!-- 解决 shiro和quartz 冲突-->
<exclusions>
<exclusion>
<groupId>org.opensymphony.quartz</groupId>
<artifactId>quartz</artifactId>
</exclusion>
</exclusions>
</dependency>

步骤2：创建定时任务

创建定时任务A

package com.demo.schedule;

/**
* 定时任务A
* @author: admin
* @date: Created in 2017/10/26
*/
public class QuartzJobA {
public void jobA(){
System.out.println("执行定时任务A...");
}
}

创建定时任务B

package com.demo.schedule;

/**
* 定时任务B
* @author : admin
* @date : Created in 2017/10/26
*/
public class QuartzJobB {
public void jobB(){
System.out.println("执行定时任务B...");
}
}

步骤3：添加spring配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 
<!-- 8. quartz配置 -->
<!-- class文件对应定时任务的路径，如果有多个定时任务就配置多个 -->
<bean id="quartzJobA" class="com.demo.schedule.QuartzJobA"/>
<bean id="quartzJobB" class="com.demo.schedule.QuartzJobB"/>

<bean id="jobDetailA" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<!-- 这里的name必须是targetObject和targetMethod -->
<property name="targetObject" ref="quartzJobA"/>
<property name="targetMethod" value="jobA"/>
</bean>

<bean id="jobDetailB" class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="quartzJobB"/>
<property name="targetMethod" value="jobB"/>
</bean>

<!-- 定义触发的条件 -->
<bean id="jobTriggerA" class="org.springframework.scheduling.quartz.CronTriggerBean">
<!-- 这里的name必须是jobDetail和cronExpression -->
<property name="jobDetail" ref="jobDetailA"/>
<!-- 每隔5秒执行一次 -->
<property name="cronExpression" value="0/5 * * * * ?"/>
</bean>
<bean id="jobTriggerB" class="org.springframework.scheduling.quartz.CronTriggerBean">
<property name="jobDetail" ref="jobDetailB"/>
<property name="cronExpression" value="0/5 * * * * ?"/>
</bean>
<!-- 总管理类，如果将lazy-init='false'，那么容器启动就会执行调度程序 -->
<bean id="startQuartz" lazy-init="false" autowire="no"
class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
<property name="triggers">
<list>
<ref bean="jobTriggerA"/>
<ref bean="jobTriggerB"/>
</list>
</property>
</bean>
</beans>

配置文件中对应关系如下

步骤4：配置web.xml文件

<!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>
<display-name>Archetype Created Web Application</display-name>
<!-- 1. 启动spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--配置一个上下文加载的监听器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>

启动tomcat服务器，控制台输入如下结果：
