Simple Example of Spring timer Quartz

The quartz Timer is used in project development. It feels like the Timer class in javaJDK. However, the difference is that the Timer provided by spring can be triggered at a fixed time every day, or at other times. The trigger time is user-friendly.

I wrote a small project and practiced it myself. The development of Spring quartz timer requires spring-context.jar and quartz. jar package, I initially did not import quartz. jar package, resulting in an error.

The maven dependency of quartz is as follows:

[Html]
<Span style = "font-size: 24px;"> <dependency>
<GroupId> org. opensymphony. quartz </groupId>
<ArtifactId> quartz-all </artifactId>
<Version> 1.6.1 </version>
</Dependency> </span>
The timer class does not need to inherit from any class.

[Java]
<Span style = "font-size: 24px;"> package com. jd. service. meeting. worker;
 
Public class MyWorker {
Public void running (){
System. out. println ("hello, world! ");
}
}
</Span>

Configure the timer in the spring configuration file.

<Span style = "font-size: 24px;"> <? Xml version = "1.0" encoding = "GBK"?>
<Beans xmlns = "http://www.springframework.org/schema/beans"
Xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance"

Default-autowire = "byName">

<Bean id = "helloWorker" class = "com. jd. service. meeting. worker. MyWorker"> </bean>
 
<Bean id = "startQuertz" lazy-init = "false" autowire = "no"
Class = "org. springframework. scheduling. quartz. SchedulerFactoryBean">
<Property name = "triggers">
<List>
<Bean class = "org. springframework. scheduling. quartz. CronTriggerBean">
<Property name = "jobDetail">
<Bean
Class = "org. springframework. scheduling. quartz. MethodInvokingJobDetailFactoryBean">
<Property name = "concurrent">
<Value> false </value>
</Property>
<Property name = "targetObject">
<Ref bean = "helloWorker"/>
</Property>
<Property name = "targetMethod">
<Value> running </value>
</Property>
</Bean>
</Property>
<Property name = "cronExpression">
<Value> 0/10 ****? </Value>
</Property>
</Bean>

</List>
</Property>
</Bean>
</Beans>
</Span>
 
This time expression specifies the trigger time rule of this timer. I specify to run every 10 seconds.

<Span style = "font-size: 24px;"> property name = "cronExpression">
<Value> 0/10 ****? </Value>
</Property> </span>
My program runs locally. You can configure the jar package.
