Integration of spring and quartz to implement timed task scheduling

There are 2 ways to integrate quartz with spring:

1. Jobdetailbean.

2. Methodinvokejobdetailfactorybean.

The following is a description of the knowledge that is used and understood and mastered.

It is important to note that when using spring integrated quartz, be sure not to forget to introduce spring-support this package:

1. Using Methodinvokejobdetailfactorybean

Second, Jobdetailbean

1. Create a job method that must inherit Quartzjobbean or implement the job method.

 Public class Testjob extends Quartzjobbean {        @Override    protectedvoid  executeinternal ( Jobexecutioncontext arg0) throws jobexecutionexception {        System.  out . println (Timeutils.getcurrenttime ());}    }

2. XML configuration

<?xml version="1.0"encoding="UTF-8"? ><beans xmlns="Http://www.springframework.org/schema/beans"Xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation="Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd "> <bean id="Jobdetail" class="Org.springframework.scheduling.quartz.JobDetailFactoryBean"> <property name="Jobclass"Value="Com.mc.bsframe.job.TestJob"></property> <property name="Durability"Value="true"></property> </bean> <bean id="Simpletrigger" class="Org.springframework.scheduling.quartz.SimpleTriggerFactoryBean"> <property name="Jobdetail" ref="Jobdetail"/> <property name="Startdelay"Value=" the"/> <property name="Repeatinterval"Value=" -"/> </bean> <!--general Management class if the lazy-init='false'Then the container starts executing the scheduler--<bean id="Startquertz"lazy-init="false"Autowire="No" class="Org.springframework.scheduling.quartz.SchedulerFactoryBean"> <!--Management trigger--<property name="triggers"> <list> <refbean="Simpletrigger"/> </list> </property> </bean></beans>

Comprehensive: The basic configuration of the scheduled task is completed.

Description of the three or two methods

With Quartzjobbean, inheritance is required. Using Methodinvokejobdetailfactorybean, you need to specify TargetObject (task instance) and Targetmethod (the method to be executed in the instance)

The latter advantage is no intrusion, business logic is simple, at a glance, the disadvantage is unable to persist (it is not clear this!)

from the experience I use, one of the most important reasons is that when the service is injected into a timed task, the latter can be injected directly, and the former needs to be schedular replaced.
