Scheduler scheduled scheduling system is required by most industrial projects. The traditional Spring-job mode is out of date, because there are many problems, especially the appending, modification and deletion of scheduled scheduling. XML needs to be modified. The configuration of XML takes effect only through hot deployment of grayscale publishing scheme or directly stopping or restarting the server, which cannot be automatically started or repaired.
Note: The application can be deployed in a cluster, and the application can be configured in a cluster or a single side. Today, we will explain how to use Spring4 + Scheduler to realize scheduling.
1. Add the Quartz JAR package to the project’s POM.xml file as follows:
Java code
lt; dependency>
org.quartz-scheduler
quartz
1.8.5
lt; /dependency>
2. Define the quartz configuration file spring-context-quartz.
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. Add the spring-context-Quartz. XML configuration file to the web
Java code
4. Define the Job entity object
Java code
5. Quartz jobServvice class
Java code
6. I will not write Controller, DAO and dao.xml related to job. In fact, it is the operation of adding, deleting, modifying and checking data
7. Start the project to verify the success of Quartz:
Project startup console:
