Quartz基本使用（三）

2019独角兽企业重金招聘Python工程师标准>>>

一、创建maven工程：XX_quartz;

二、在pom.xml文件中增加quartz及spring相关架包；

三、增加web组件

四、编写相关任务执行逻辑代码；

MyBean类型

@Component("myBean")
public class MyBean {
	public void printMessage() {
		// 打印当前的执行时间，格式为2017-01-01 00:00:00
		Date date = new Date();
		SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		System.out.println("MyBean Executes!" + sf.format(date));
	}
}

FirstSchedulerJob类型

public class FirstScheduledJob extends QuartzJobBean{
     private AnotherBean anotherBean;
     
     public void setAnotherBean(AnotherBean anotherBean){
    	 this.anotherBean = anotherBean;
     }

	@Override
	protected void executeInternal(JobExecutionContext arg0)
			throws JobExecutionException {
		Date date = new Date();
		SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		System.out.println("FirstScheduledJob Executes!" + sf.format(date));
		this.anotherBean.printAnotherMessage();		
	}
}

 AnotherBean类型

@Component("anotherBean")
public class AnotherBean {
	public void printAnotherMessage() {
		System.out.println("AnotherMessage");
	}
}

增加spring配置xml文件（dispatcher-servlet.xml）;

<!-- 添加注解驱动 -->
	<mvc:annotation-driven />
	<!-- 默认扫描的包路径 -->
	<context:component-scan base-package="com.XX.springquartz" />
    <!-- 程序启动立马执行 -->
	<bean id="simpleJobDetail"
		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
        <!-- 通过扫描得到带有注解@compant("myBean")的java类【目标执行类】 -->
		<property name="targetObject" ref="myBean" />
        <!-- 通过扫描得到带有注解@compant("myBean")的java类【目标类中方法】 -->
		<property name="targetMethod" value="printMessage" />
	</bean>
    <!-- 导入JobDetail配置 -->
	<bean id="firstComplexJobDetail"
		class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
        <!-- 指向继承QuqartzBean父类的java任务执行类 -->
		<property name="jobClass"
			value="com.XX.springquartz.quartz.FirstScheduledJob" />
        <!--通过扫描得到带有注解@compant("anotherBean")的java类通过set传参方式得到其anotherBean
             执行方法
         --> 
		<property name="jobDataMap">
			<map>
				<entry key="anotherBean" value-ref="anotherBean" />
			</map>
		</property>
        <!--   -->
		<property name="Durability" value="true"/>				
	</bean>
	<!-- 距离当前时间1秒之后执行，之后每隔两秒钟执行一次 -->
	<bean id="mySimpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">
	    <property name="jobDetail"  ref="simpleJobDetail"/>
	    <property name="startDelay"  value="1000"/>
	    <property name="repeatInterval"  value="2000"/>
	</bean>
	
	<!-- 每隔5秒钟执行一次 -->
	<bean id="myCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
	    <property name="jobDetail"  ref="firstComplexJobDetail"/>
	    <property name="cronExpression"  value="0/5 * * ? * *"/>
	</bean>
	
	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
	    <property name="jobDetails">
	        <list>
	            <ref bean="simpleJobDetail"/>
	            <ref bean="firstComplexJobDetail"/>
	        </list>
	    </property>
	    <property name="triggers">
	        <list>
	            <ref bean="mySimpleTrigger"/>
	            <ref bean="myCronTrigger"/>
	        </list>
	    </property>
	</bean>

五、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	version="3.0">
	<display-name>Archetype Created Web Application</display-name>
	<!-- spring MVC的核心就是DispatcherServlet，使用springMVC的第一步就是将下面的servlet放入web.xml 
		servlet-name属性非常重要，默认情况下，DispatchServlet会加载这个名字-servlet.xml的文件，如下，就会加载 dispather-servlet.xml，也是在WEN-INF目录下。 -->
	<servlet>
		<servlet-name>dispatcher</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<!-- 设置dispatchservlet的匹配模式，通过把dispatchservlet映射到/，默认servlet会处理所有的请求，包括静态资源 -->
	<servlet-mapping>
		<servlet-name>dispatcher</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>

</web-app>
