Spring4+springmvc+quartz realization of multi-thread dynamic timing scheduling

Scheduler timing Scheduling system is required for most industry projects, the traditional spring-job mode, the personal feeling has been out, because there are a lot of problems, especially the timing of the addition of scheduling, modification, deletion, need to modify the XML, XML configuration in effect is nothing more than a hot deployment of gray-scale publishing scheme or directly stop, restart the server, completely can not do automatic startup, repair mode.

Reminder: The application can be deployed in a cluster, in the timing of scheduling configuration can use cluster mode or unilateral configuration application, today is the use of Spring4+scheduler to implement timing scheduling, gossip less, directly to the steps recorded:

1. In the project's Pom.xml file, introduce the Quartz jar package as follows:

Java code

Lt;dependency>

Org.quartz-scheduler

Quartz

1.8.5

Lt;/dependency>

2. Define the Quartz configuration file Spring-context-quartz.xml:

Java code

xmlns:context= "Http://www.springframework.org/schema/context" xsi:schemalocation= "

Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

Http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd "

Default-lazy-init= "false" >

3. Introduction of the Spring-context-quartz.xml configuration file in the project's Web. xml file

Java code

4. Defining the Job Entity object

Java code

5. Write the Jobservvice class for Quartz:

Java code

6. Writing related job Controller, DAO, Dao.xml I will not write on this side, in fact, the data to delete and change the operation

7. Start the project to verify that the quartz is successful:

Project launches a console:
