定时任务Quartz_spring的配置文件

Quartz定时任务整合spring的配置文件(applicationContext.xml)

web.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"

        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>

        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <!-- spring的核心监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

解决Spring+Quartz无法自动注入bean问题

package com.douyu.quartz.service;

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;
import org.springframework.stereotype.Service;

@Service("jobFactory")
public class JobFactory extends AdaptableJobFactory{

    @Autowired
    private AutowireCapableBeanFactory capableBeanFactory;
    
    @Override
    protected Object createJobInstance(TriggerFiredBundle bundle)
            throws Exception {
        Object jobInstance = super.createJobInstance(bundle);
        capableBeanFactory.autowireBean(jobInstance);
        return jobInstance;
    }
}

另外一种解决方案

在Job类的excute方法下写入

SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);

这样,在job类中使用@autowired 就可以完成jobDetail的注入;这样在applicationContext.xml的scheduler配置中也不用在注入jobFactory
