最近在写定时任务，以前没接触过。查了些相关资料说使用quartz定时框架。
需要配置文件：config-quartz.xml
相关配置如下(红色部分是之后添加的，在后面步骤会说明)：
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.0.xsd">
quartz.properties
#============================================================================
# Configure Main Scheduler Properties
#============================================================================
org.quartz.scheduler.instanceName = WrhFrameScheduler
org.quartz.scheduler.instanceId = AUTO
org.quartz.scheduler.skipUpdateCheck = true
#============================================================================
# Configure ThreadPool
#============================================================================
org.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool
org.quartz.threadPool.threadCount = 12
org.quartz.threadPool.threadPriority = 5
#============================================================================
# Configure JobStore
#============================================================================
org.quartz.jobStore.misfireThreshold = 60000
org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore
#org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
#org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.PostgreSQLDelegate
#org.quartz.jobStore.useProperties = false
#org.quartz.jobStore.dataSource = myDS
#org.quartz.jobStore.tablePrefix = QRTZ_
#org.quartz.jobStore.isClustered = false
#============================================================================
# Configure Datasources
#============================================================================
#org.quartz.dataSource.myDS.driver = org.postgresql.Driver
#org.quartz.dataSource.myDS.URL = jdbc:postgresql://localhost/dev
#org.quartz.dataSource.myDS.user = jhouse
#org.quartz.dataSource.myDS.password =
#org.quartz.dataSource.myDS.maxConnections = 5
最后spring-mvc.xml配置文件中奖quartz.xml文件引入即可：
然后写测试类开始测试定时任务：
package com.wy.care60.job;
import com.wy.care60.dao.MElementMapper;
import com.wy.care60.dao.MInterEnumMapper;
import com.wy.care60.dao.MProjectMapper;
import com.wy.care60.model.MInterEnum;
import com.wy.care60.model.MProject;
import org.apache.tools.ant.Project;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.QuartzJobBean;
import org.springframework.stereotype.Component;
import javax.annotation.Resource;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.List;
/**
* Created by Administrator on 2017/12/20.
*/
@Component
public class HealthPlanJob extends QuartzJobBean {
@Autowired
MProjectMapper mProjectMapper;
@Override
public void executeInternal(JobExecutionContext jobExecutionContext) throws JobExecutionException {
System.out.println(new Date());
}
}
发现时间可以打印出来，证明定时任务成功开启；但是同时也发现了一个问题，就是依赖注入的 mProjectMapper值为null。
开始以为是Spring的原因，导致注解失败，后来查了相关资料发现，不是Spring的原因，而是因为：这个Job是由quartz实例化出来的，不受Spring的管理，所以就导致注入失败。解决办法是自己new一个类，让Spring实例化这个类，代码如下
import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.scheduling.quartz.AdaptableJobFactory;
public class MyJobFactory extends AdaptableJobFactory {
@Autowired
private AutowireCapableBeanFactory capableBeanFactory;
protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
//调用父类的方法
Object jobInstance = super.createJobInstance(bundle);
capableBeanFactory.autowireBean(jobInstance);
return jobInstance;
}
}
然后把这个类配置到Spring中去，(config-quartz.xml中红色部分)
然后在把org.springframework.scheduling.quartz.SchedulerFactoryBean的jobFactory设置成我们自己的。(config-quartz.xml中红色部分)
config-quartz.xml完整版如下：
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.0.xsd">
到这为止，成功！
以上这篇JAVA使用quartz添加定时任务,并依赖注入对象操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
