spring 整合 Quartz 定时任务

1、Quartz 定时任务功能强大，应用场景也十分广泛。直接上代码

1.0、定义一个要定时执行的方法

package com.fbank.demo.web;

import org.springframework.stereotype.Component;
import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * Quartz定时任务执行的类：被spring管理，注入其他spring对象
 */
@Component
public class QuartzTest {

    @Autowired
    private IRedisService redisService;

    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    //定时执行方法
    public void execute(){
        System.out.println("定时任务执行了："+sdf.format(new Date()));
    }
} 

1.1、maven添加依赖：（spring-context-support-4.3.14.RELEASE.jar）

<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-context-support</artifactId>
  <version>4.3.14.RELEASE</version>
</dependency>

1.2、在spring 能加载到的地方引入配置文件

1.3、applicationContext-quartz.xml 在 resources 目录下

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context"
   xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx"

   xmlns:task="http://www.springframework.org/schema/task" xmlns:jee="http://www.springframework.org/schema/jee"
   xsi:schemaLocation="

         http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd"
   >

   <!--定时执行类 -->
   <bean id="quartzTest" class="com.fbank.demo.web.QuartzTest" />

   <bean name="quartzTestJob"
       class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
       <property name="targetObject" ref="quartzTest" /><!--目标对象-->
       <property name="targetMethod">
          <value>execute</value><!--目标方法-->
       </property>
       <property name="concurrent"><!--配置为false不允许任务并发执行-->
          <value>false</value>
       </property>
   </bean>

   <!--配置定时器-->
  <bean id="quartzTestTrigger" class="org.springframework.scheduling.quartz.CronTriggerFactoryBean">
          <!-- 触发bean配置 -->  
         <property name="jobDetail" ref="quartzTestJob"/>
          <!-- 触发时间配置 -->
          <property name="cronExpression">
           <!--cron表达式：每隔五秒钟触发，也可从配置读取-->
           <value>0/5 * * * * ?</value>
             <!--<value>${quartzTestTrigger}</value>-->
          </property>
      </bean>

      <!-- 调度任务触发器，启动定时任务-->
   <bean autowire="no" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" destroy-method="destroy">
      <property name="triggers">
         <list>
             <ref bean="quartzTestTrigger"/>
         </list>
      </property>
   </bean> 
</beans>

2、项目启动后，被spring 管理的 Quartz 就开始执行了
