在上一章節：Quartz定時任務（附demo）（一）中我們介紹瞭如何利用quartz創建一個普通的定時任務，本文將介紹spring與quartz的整合，讓服務器啓動時就運行定時任務
項目結構如下圖：
步驟1：引入依賴包
<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面向切面編程 -->
<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>
<!-- 指定編譯版本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,由於idea編譯的時候不會把src/main/java中的xml文件編譯的class中，需要添加下面語句，eclipse則不用 -->
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.xml</include>
</includes>
</resource>
</resources>
</build>
</project>注意事項：
- spring3.1以下的版本必須使用quartz 2以下的版本，spring 3.1以上的版本必須使用quartz 2以上的版本，否則會報錯
- 如果項目中同時使用了shiro框架，在引入shiro依賴包的時候需要排除quartz包，否則會報錯，如下：
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-quartz</artifactId>
<version>1.2.5</version>
<!-- 解決 shiro和quartz 衝突-->
<exclusions>
<exclusion>
<groupId>org.opensymphony.quartz</groupId>
<artifactId>quartz</artifactId>
</exclusion>
</exclusions>
</dependency>步驟2：創建定時任務
創建定時任務A
package com.demo.schedule;
/**
* 定時任務A
* @author: admin
* @date: Created in 2017/10/26
*/
public class QuartzJobA {
public void jobA(){
System.out.println("執行定時任務A...");
}
}創建定時任務B
package com.demo.schedule;
/**
* 定時任務B
* @author : admin
* @date : Created in 2017/10/26
*/
public class QuartzJobB {
public void jobB(){
System.out.println("執行定時任務B...");
}
}步驟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文件對應定時任務的路徑，如果有多個定時任務就配置多個 -->
<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">
<!-- 這裏的name必須是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>
<!-- 定義觸發的條件 -->
<bean id="jobTriggerA" class="org.springframework.scheduling.quartz.CronTriggerBean">
<!-- 這裏的name必須是jobDetail和cronExpression -->
<property name="jobDetail" ref="jobDetailA"/>
<!-- 每隔5秒執行一次 -->
<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>
<!-- 總管理類，如果將lazy-init='false'，那麼容器啓動就會執行調度程序 -->
<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>配置文件中對應關係如下
步驟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. 啓動spring容器 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<!--配置一個上下文加載的監聽器-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>啓動tomcat服務器，控制檯輸入如下結果：
