  • spring Quartz基于配置文件和注解的实现

    这里仅仅是做简单的记录怎样实现。

    一、基于配置文件的实现

           ①编写须要调度的类

    package com.study;
    
    import org.springframework.scheduling.annotation.Scheduled;
    import org.springframework.stereotype.Component;
    //@Component
    public class QuartzJob {
    	public QuartzJob(){
    		System.out.println("Quartzjob创建成功");
    	}
    	//@Scheduled(cron = "0/1 * *  * * ? ")
    	public void run(){
    		System.out.println("Quartz运行的任务调度");
    	}
    }

    注:里面的注解是后面的是注解的实现中用到的

           ②设置配置文件spring-quartz.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
    
    <beans>
    	<bean id="quartzJob" class="com.study.QuartzJob"></bean>
    	<!-- 定义调用对象和调用对象的方法 -->
    	<bean id="jobtask"
    		class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
    		<!-- 调用的类 -->
    		<property name="targetObject">
    			<ref bean="quartzJob" />
    		</property>
    		<!-- 调用类中的方法 -->
    		<property name="targetMethod">
    			<value>run</value>
    		</property>
    	</bean>
    	<!-- 定义触发时间 -->
    	<bean id="doTime" class="org.springframework.scheduling.quartz.CronTriggerBean">
    		<property name="jobDetail">
    			<ref bean="jobtask" />
    		</property>
    		<!-- cron表达式 -->
    		<property name="cronExpression">
    			<!--<value>10,15,20,25,30,35,40,45,50,55 * * * * ?</value>-->
    			<value>0/1  * * * * ?</value>
    		</property>
    	</bean>
    	<!-- 总管理类 假设将lazy-init='false'那么容器启动就会运行调度程序  -->
    	<bean id="startQuertz" lazy-init="false" autowire="no"
    		class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
    		<property name="triggers">
    			<list>
    				<ref bean="doTime" />
    			</list>
    		</property>
    	</bean>
    
    </beans>
         注意cron表达式,这里配置的是每隔1s运行。
         

          ③启动spring容器

    package com.study;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class Test {
    	public static void main(String[] args) {
    		System.out.println("启动spring容器");
    		ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring-quartz.xml");
    	}
    }

    二、基于注解的实现

          ①配置须要调度的类,并加入注解

    package com.study;
    
    import org.springframework.scheduling.annotation.Scheduled;
    import org.springframework.stereotype.Component;
    @Component
    public class QuartzJob {
    	public QuartzJob(){
    		System.out.println("Quartzjob创建成功");
    	}
    	@Scheduled(cron = "0/1 * *  * * ? ")
    	public void run(){
    		System.out.println("Quartz运行的任务调度");
    	}
    }
    

         ②加入配置文件

    <?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-3.0.xsd   
        http://www.springframework.org/schema/context   
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/task 
        http://www.springframework.org/schema/task/spring-task-3.0.xsd  " >
        <task:annotation-driven/>  
        <context:component-scan base-package="com.study"/>
        <context:annotation-config/>
    </beans>
    	
    

         ③启动容器,这里通过配置web.xml启动

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" 
    	xmlns="http://java.sun.com/xml/ns/javaee" 
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    	<context-param>
    		<param-name>contextConfigLocation</param-name>
    		<param-value>classpath:spring-quartz2.xml</param-value>
    	</context-param>
    	<listener>
    		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    	</listener>
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
    </web-app>

    这里不知道为何採用ClassPathXMLApplicationContext启动时,报错。看两种方式的配置文件不同,预计是解析xml文件的方式不同。(dom/sax)
