Quartz和SpringMVC，Spring整合
1.Quartz依赖的包如下：
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-context-support</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-tx</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>2.2.3</version>
</dependency>
使用Quartz配置作业的方式
第一种：MethodInvokingJobDetailFactoryBean，在dispatcher-servlet.xml中配置
<bean id="simpleJobDetail"
class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
<property name="targetObject" ref="myBean" />
<property name="targetMethod" value="printMessage" />
</bean>
SimpleTrigger的相关配置
<!-- 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>
其中myBean的相关代码如下
@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));
}
}
第二种：JobDetailFactoryBean，在dispatcher-servlet.xml中配置
<bean id="firstComplexJobDetail"
class="org.springframework.scheduling.quartz.JobDetailFactoryBean">
<property name="jobClass"
value="com.imooc.springquartz.quartz.FirstScheduledJob" />
<property name="jobDataMap">
<map>
<entry key="anotherBean" value-ref="anotherBean" />
</map>
</property>
<property name="Durability" value="true"/>
</bean>
anotherBean的相关代码如下：
@Component("anotherBean")
public class AnotherBean {
public void printAnotherMessage() {
System.out.println("AnotherMessage");
}
}
FirstScheduledJob类相关代码如下
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();
}
}
myCronTrigger的相关配置如下
<!-- 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>
两种方法的Scheduler的相关配置
<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>
完整项目如下：
