最近在寫定時任務(wù)，以前沒接觸過。查了些相關(guān)資料說使用quartz定時框架。

需要配置文件：config-quartz.xml

相關(guān)配置如下(紅色部分是之后添加的，在后面步驟會說明)：

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配置文件中獎quartz.xml文件引入即可：

然后寫測試類開始測試定時任務(wù)：

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());

}

}

發(fā)現(xiàn)時間可以打印出來，證明定時任務(wù)成功開啟；但是同時也發(fā)現(xiàn)了一個問題，就是依賴注入的 mProjectMapper值為null。

開始以為是Spring的原因，導(dǎo)致注解失敗，后來查了相關(guān)資料發(fā)現(xiàn)，不是Spring的原因，而是因為：這個Job是由quartz實例化出來的，不受Spring的管理，所以就導(dǎo)致注入失敗。解決辦法是自己new一個類，讓Spring實例化這個類，代碼如下

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 {

//調(diào)用父類的方法

Object jobInstance = super.createJobInstance(bundle);

capableBeanFactory.autowireBean(jobInstance);

return jobInstance;

}

}

然后把這個類配置到Spring中去，(config-quartz.xml中紅色部分)

然后在把org.springframework.scheduling.quartz.SchedulerFactoryBean的jobFactory設(shè)置成我們自己的。(config-quartz.xml中紅色部分)

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">

到這為止，成功！
