Quartz與Spring集成(三)(七)

使用Maven進行開發，集成步驟如下：

pom.xml中添加依賴

web.xml中添加SpringMVC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的第一步就是將下面的servlet放入web.xml 
        servlet-name屬性非常重要，默認情況下，DispatchServlet會加載這個名字-servlet.xml的文件，如下，就會加載 dispather-servlet.xml，也是在WEN-INF目錄下。 -->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <!-- 設置dispatchservlet的匹配模式，通過把dispatchservlet映射到/，默認servlet會處理所有的請求，包括靜態資源 -->
    <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>

在dispatcher-servlet.xml中對SpringMVC進行配置，同時對Quartz進行集成

<?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"

            http://www.springframework.org/schema/context/spring-context.xsd"
    default-lazy-init="true">

    <!-- 通過mvc:resources設置靜態資源，這樣servlet就會處理這些靜態資源，而不通過控制器 -->

    <!-- mvc:view-controller可以在不需要Controller處理request的情況，轉向到設置的View -->
    <!-- 像下面這樣設置，如果請求爲/，則不通過controller，而直接解析爲/index.jsp -->
    <mvc:view-controller path="/" view-name="index" />
    <bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass"
            value="org.springframework.web.servlet.view.JstlView"></property>

        <property name="jobDataMap">

                <entry key="anotherBean" value-ref="anotherBean" />

        </property>
        <!-- -->
        <property name="Durability" value="true"/>

    <!-- 距離當前時間1秒之後執行，之後每隔兩秒鐘執行一次 -->
    <bean id="mySimpleTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean">

        <property name="startDelay"  value="1000"/>
        <property name="repeatInterval"  value="2000"/>
    </bean>

    <!-- 每隔5秒鐘執行一次 -->

        <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>
</beans>

上述xml中myBean類如下：

package com.imooc.springquartz.quartz;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.springframework.stereotype.Component;

@Component("myBean")
public class MyBean {
    public void printMessage() {
        // 打印當前的執行時間，格式爲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));
    }
}

anotherBean類如下：

package com.imooc.springquartz.quartz;

import org.springframework.stereotype.Component;

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

FirstScheduledJob類如下：

package com.imooc.springquartz.quartz;

import java.text.SimpleDateFormat;
import java.util.Date;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

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();     
    }
}
