Usage Environment: ECLIPSE+MAVEN+SPRING+QUARTZ1
Use purpose: Perform the timer to complete the scan operation.
Puzzle point: Using the QUARTZ2 version will appear inexplicable errors, similar to the interface and class definition of the difference. Look at the document and don't get it straight.
Use steps:
1. Configure the MAVEN profile (configured with the QUARTZ1 version), pom.xml add the code:
| The code is as follows |
Copy Code |
| <!--add Quartz frame-->
<dependency>
<groupId>org.quartz-scheduler</groupId>
<artifactId>quartz</artifactId>
<version>1.8.5</version>
</dependency> <!--components Optional-->
<!--start-->
<dependency>
<groupId>javax.transaction</groupId>
<artifactId>jta</artifactId>
<version>1.1</version>
</dependency> <dependency>
<groupId>commons-digester</groupId>
<artifactId>commons-digester</artifactId>
<version>1.8</version>
</dependency> <dependency>
<groupId>commons-beanutils</groupId>
<artifactId>commons-beanutils</artifactId>
<version>1.8.3</version>
</dependency>
<!--end-->
2. Configure the Spring profile Spring.xml file to load the Quartz. configuration file with the following code:
<!--: Using Methodinvokingjobdetailfactorybean, the task class can specify the calling method by Targetmethod without implementing the job interface-->
<!--define methods in the target bean and bean-->
<bean id= "Springqtzjob"
class= "Com.founder.centerbusiness.controller.basicMgr.RuleMgrController"/>
<bean id= "Springqtzjobmethod"
class= "Org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean" >
<property name= "TargetObject" >
<ref bean= "Springqtzjob"/>
</property>
<property name= "Targetmethod" > <!--the name of the method to be executed-->
<value>execute</value>
</property>
</bean> <!--======================== scheduling trigger ========================-->
<bean id= "Crontriggerbean" class= "Org.springframework.scheduling.quartz.CronTriggerBean" >
<property name= "Jobdetail" ref= "Springqtzjobmethod" ></property>
<!--0/1 * * * *? : Perform a--> scan every second
<property name= "cronexpression" value= "0/1 * * * *?" ></property>
</bean> <!--======================== Dispatch factory ========================-->
<bean id= "Springjobschedulerfactorybean"
class= "Org.springframework.scheduling.quartz.SchedulerFactoryBean" >
<property name= "Triggers" >
<list>
<ref bean= "Crontriggerbean"/>
</list>
</property>
</bean> which
<!--0/2 * * * *? : Perform a--> scan every second
<property name= "cronexpression" value= "0/2 * * * *?" ></property>
That's a scan every 1 seconds.
<!--0/8 * * * *? : Perform a--> scan every 8 seconds
<property name= "cronexpression" value= "0/8 * * * *?" ></property>
That's a scan every 8 seconds.
What is the meaning of the specific *, to ask the degree of the Empress. Id= "Springqtzjob" represents the local file path in which the action is performed.
3. Local execution Java file code is as follows:
/**
* Execution Timer
*/
protected void execute () {
String currenttime = Dateutils.getdatetime ();
System.out.println ("Current Time--->" + currenttime);
} |
